A paper entitled “Coarticulation and coordination in phonological development: Insights from children’s and adults’ production of complex–simplex stop contrasts in Gã” (Kpogo & Chang, 2025) has been published in the Journal of Phonetics.
Abstract: Achieving adult-like coarticulation, which relies on precise gestural coordination, is known to be a challenging aspect of phonological development. Unique coordination challenges are posed by doubly articulated stops, typologically uncommon complex consonants that show crosslinguistic variation in their acoustic contrast with simplex (singly articulated) consonants. We examined the acoustics and development of complex–simplex stop contrasts between labio-velars (/k͡p/, /ɡ͡b/) and bilabials (/p/, /b/) in Gã (Niger-Congo, Kwa), with special attention to coarticulation with adjacent sonorants. We found that Gã adults mostly produced differences in voice onset time and closure duration to implement these contrasts, and Gã five-year-olds also produced differences in these dimensions. Crucially, however, five-year-olds also produced significant differences in onset formants, which adults did not. These findings provide evidence of age-graded variation in the implementation of complex–simplex stop contrasts in Gã, suggesting that over the course of development there may be a shift away from production of carryover coarticulatory differences toward greater reliance on durational differences. We argue that children’s initial reliance on carryover coarticulation capitalizes on a tendency toward greater consonant–vowel coarticulation as compared to adults, discussing implications for our understanding of how coarticulation develops.

de Leeuw & Chang in CUP Handbook
Published:
A chapter entitled “Phonetic and phonological L1 attrition and drift in bilingual speech” (de Leeuw & Chang, 2024) has been published by Cambridge University Press in The Cambridge Handbook of Bilingual Phonetics and Phonology, edited by Mark Amengual.
Abstract: This chapter presents an overview of what is currently known about phonetic and phonological first language (L1) attrition and drift in bilingual speech and introduces a new theory of bilingual speech, Attrition & Drift in Access, Production, and Perception Theory (ADAPPT). Attrition and drift are defined and differentiated along several dimensions, including duration of change, source in second language (L2) experience, consciousness, agency, and scope. We address why findings of attrition and drift are important for our overall understanding of bilingual speech and draw links between ADAPPT and well-known theories of L2 speech, such as the revised Speech Learning Model (SLM-r), the Perceptual Assimilation Model-L2 (PAM-L2), and the Second Language Linguistic Perception model (L2LP). The significance of findings revealing attrition and drift is discussed in relation to different linguistic subfields. The chapter raises the question of how attrition and drift potentially interact to influence speech production and perception in the bilingual’s L1 over the life span; additional directions for future research are pointed out as well.

Kpogo, Kohut & Chang in LSP volume

A paper entitled “Expressing diminutive meaning in heritage Twi: The role of complexity and language-specific preferences” (Kpogo, Kohut, & Chang, 2024) has been published by Language Science Press in the edited volume Formal Approaches to Complexity in Heritage Language Grammars.
Abstract: Twi (Akan) and English can both express diminutive meaning using a morphological strategy (diminutive suffix) or a syntactic strategy (adjectival construction), but they differ with respect to native-speaker preferences -- morphological in Twi, syntactic in English. Each strategy in Twi, moreover, is associated with different types of complexity (morphological, phonological, lexical, discourse-pragmatic, and/or inhibitory). In this study, we examined whether English-dominant, second-generation (G2) speakers of Twi in the US would express diminutive meaning in Twi differently from first-generation (G1) speakers. Results from elicited production suggest that G2 does indeed differ from G1 in this respect: whereas G1 relies on the morphological strategy, G2 relies on the syntactic strategy, producing adjectives post-nominally in accordance with Twi syntax. These results are discussed in light of variation in G2 speakers' morphological awareness and verbal fluency in Twi. Overall, our findings suggest that both the incremental complexity of linguistic options within a bilingual language repertoire and cross-linguistic influence at the level of preferences play a role in explaining G2's diminutive production.

Chang & Yao in CUP volume
Published:
A paper entitled “An individual-differences perspective on variation in heritage Mandarin speakers” (Chang & Yao, 2024) has been published by Cambridge University Press in the book The Phonetics and Phonology of Heritage Languages (edited by Rajiv Rao).
Abstract: This chapter takes an individual-differences perspective on the dual sound systems of American heritage speakers (HSs) of Mandarin Chinese. Based on detailed sociodemographic data and production data on segmentals and suprasegmentals, we build holistic demographic and phonetic profiles for HSs, as well as native speakers and late learners, to explore how different aspects of their two languages (Mandarin, English) may develop in relation to each other and how individual variation in production may be related to socio-demographic factors. Using multiple factor analysis (MFA), we describe the range of these profiles, identify clusters of variation defined by different sociodemographic factors, and argue that some factors (e.g., age of arrival, language(s) spoken at home) have more predictive power for phonetic profiles than others. Overall, our results suggest a significant, if limited, link between socio-demographic factors and production, but only in Mandarin. We conclude by discussing the advantages and disadvantages of group-based and individual-centered approaches.

Brown-Bousfield & Chang in JBP book
Published:
A paper entitled “Regressive cross-linguistic influence in multilingual speech rhythm: The role of language similarity” (Brown-Bousfield & Chang, 2023) has been published by John Benjamins Publishing in the edited volume L3 Development After the Initial State.
Abstract: While previous work on multilingual speech rhythm has found evidence of progressive cross-linguistic influence of a first or second language (L1, L2) on a third language (L3), regressive cross-linguistic influence (rCLI) in rhythm remains understudied. In the current study, we tested the roles of order of acquisition and of language similarity in shaping rCLI from syllable-timed Spanish as L3 to stress-timed English and German as L1/L2. In a picture narration task, adult sequential trilinguals (L1 English-L2 German-L3 Spanish, L1 German-L2 English-L3 Spanish) and sequential bilingual controls (L1 English-L2 German, L1 German-L2 English) produced semi-spontaneous speech in each of their languages, which was analyzed in terms of the rhythm metric VarcoV. Results showed evidence of rCLI in English (the typologically more similar language to Spanish) but no evidence of rCLI in German; however, rCLI in English was found only when English was the L1. On the basis of these findings, we propose the Similarity Convergence Hypothesis (SCH), which claims that previously acquired languages that are more similar to a later-acquired language are relatively more vulnerable to rCLI from this language.

Chang & Fraser in LSA Proceedings
Published:
A paper entitled “On the auditory identifiability of Asian American identity in speech: The role of listener background, sociolinguistic awareness, and language ideologies” (Chang & Fraser, 2023) has been published in the Proceedings of the Linguistic Society of America.
Abstract: The current study examined the auditory identifiability of Asian American ethnoracial identity, including the role of listener characteristics and ideologies. Results of an identification experiment showed that the overall accuracy of ethnoracial identification on (East and Southeast) Asian talkers was low, but not the lowest among talker groups and not significantly different from accuracy on Black talkers. There were also significant effects of listeners' ethnoracial identity, gender, and linguistic chauvinism (i.e., disfavoring linguistic diversity in the US). In particular, being Asian or a woman was associated with a higher likelihood of accuracy, whereas greater linguistic chauvinism was, to an extent, associated with a lower likelihood of accuracy. Results of a discrimination experiment additionally showed an effect of listeners' awareness of ethnoracially-based language variation: having this awareness was associated with a higher likelihood of accuracy on discrimination trials with one or more Asian talkers. Taken together, these findings converge with previous results showing an effect of the listener's background on ethnoracial perception and further implicate the listener's sociolinguistic awareness and ideologies.

Kellogg & Chang in Languages
Published:
A paper entitled “Exploring the onset of phonetic drift in voice onset time perception” (Kellogg & Chang, 2023) has been published in the open-access journal Languages.
Abstract: Recent exposure to a second or foreign language (FL) can influence production and/or perception in the first language (L1), a phenomenon referred to as phonetic drift. The smallest amount of FL exposure shown to effect drift in perception is 1.5 hours (Gong et al. 2016). The present study examined L1 perception at earlier timepoints of FL exposure, to determine whether the phonetic system is able to resist FL influence at an incipient stage. In a longitudinal pre-test/post-test design, L1 English listeners were exposed to Tagalog under different conditions varying in attention directed to the voice onset time (VOT) plosive contrast in the FL; they then completed an identification task on L1 tokens from VOT continua. In every condition, the likelihood of “voiceless” identifications decreased. This change indicates a shift towards a longer VOT crossover point between “voiced” and “voiceless”, consistent with dissimilatory drift in perception. Listeners in a control condition, however, displayed a similar, albeit less lasting, change in L1 judgments, suggesting that the change arose partly from a task effect. We conclude by discussing directions for future research on phonetic drift in perception.

Chang & Ahn in Languages
Published:
A paper entitled “Examining the role of phoneme frequency in first language perceptual attrition” (Chang & Ahn, 2023) has been published in the open-access journal Languages.
Abstract: In this paper, we follow up on previous findings concerning first language (L1) perceptual attrition to examine the role of phoneme frequency in influencing variation across L1 contrasts. We hypothesized that maintenance of L1 Korean contrasts (i.e., resistance to attrition) in L1 Korean-L2 English bilinguals would be correlated with frequency, such that better-maintained contrasts would also be more frequent in the L1. To explore this hypothesis, we collected frequency data on three Korean contrasts (/n/-/l/, /t/-/t*/, /s/-/s*/) and compared these data to perceptual attrition data from a speeded sequence recall task testing the perception and phonological encoding of the target contrasts. Results only partially supported the hypothesis. On the one hand, /n/-/l/, the best-maintained contrast, was the most frequent contrast overall. On the other hand, /n/-/l/ also evinced the greatest frequency asymmetry between the two members of the contrast (meaning that it was the least important to perceive accurately); furthermore, /s/-/s*/, which was less well maintained than /t/-/t*/, was actually more frequent than /t/-/t*/. These results suggest that disparities in perceptual attrition across contrasts cannot be attributed entirely to frequency differences. We discuss the implications of the findings for future research examining frequency effects in L1 perceptual change.

Paper in POMA
Published:
A paper entitled “Unity and diversity in Asian American language variation: Data from Chinese, Filipino, Korean, and Vietnamese Americans” (Chang & Dionne, 2022) has been published in the open-access journal Proceedings of Meetings on Acoustics.
Abstract: The present study examined sociophonetic variation in a small sample of Asian Americans in Boston, Massachusetts representing four ethnic groups: Chinese, Filipino, Korean, and Vietnamese. Analyzing these speakers’ English production in tasks eliciting both casual and careful speech, we focused on four linguistic features comprising features observed in Eastern New England and in certain Asian American groups. Three features (R-DELETION, L-VOCALIZATION, L/R-CONFLATION) were coded auditorily and one (LOW BACK RAISING of /ɑ/ to /ɔ/) acoustically. Overall, results showed low use of Eastern New England features (R-DELETION, LOW BACK RAISING), high use of L-VOCALIZATION, and no use of L/R-CONFLATION, but also significant differences in specific patterns of use according to ethnicity and speech style. Ethnicity was a significant predictor of the occurrence of R-DELETION and L-VOCALIZATION, and also a significant predictor of first formant (F1) values in the low back vowels, although no clear vowel merger was found. Careful speech showed lower rates of R-DELETION and L-VOCALIZATION and less overlap of the low back vowels as compared to casual speech. These findings reveal similarities and differences in speech production among ethnically diverse Asian Americans and highlight the need for further investigation of phonetic variation within this community.

Paper in JASA-EL
Published:
A paper entitled “Intoxication and pitch control in tonal and non-tonal language speakers” (Tang, Chang, Green, Bao, Hindley, Kim, & Nevins, 2022) has been published in the open-access journal JASA Express Letters.
Abstract: Alcohol intoxication is known to affect pitch variability in non-tonal languages. In this study, intoxication's effects on pitch were examined in tonal and non-tonal language speakers, in both their native language (L1; German, Korean, Mandarin) and nonnative language (L2; English). Intoxication significantly increased pitch variability in the German group (in L1 and L2), but not in the Korean or Mandarin groups (in L1 or L2), although there were individual differences. These results support the view that pitch control is related to the functional load of pitch and is an aspect of speech production that can be advantageously transferred across languages, overriding the expected effects of alcohol.

Paper in PLoS ONE (Lopiccolo & Chang)
Published:
A paper entitled “Cultural factors weaken but do not reverse left-to-right spatial biases in numerosity processing: Data from Arabic and English monoliterates and Arabic-English biliterates” (Lopiccolo & Chang, 2021) has been published in the open-access journal PLoS ONE.
Abstract: Directional response biases due to a conceptual link between space and number, such as a left-to-right hand bias for increasing numerical magnitude, are known as the SNARC (Spatial-Numerical Association of Response Codes) effect. We investigated how the SNARC effect for numerosities would be influenced by reading-writing direction, task instructions, and ambient visual environment in four literate populations exemplifying opposite reading-writing cultures—namely, Arabic (right-to-left script) and English (left-to-right script). Monoliterates and biliterates in Jordan and the U.S. completed a speeded numerosity comparison task to assess the directionality and magnitude of a SNARC effect in their numerosity processing. Monoliterates’ results replicated previously documented effects of reading-writing direction and task instructions: the SNARC effect found in left-to-right readers was weakened in right-to-left readers, and the left-to-right group exhibited a task-dependency effect (SNARC effect in the smaller condition, reverse SNARC effect in the larger condition). Biliterates’ results did not show a clear effect of environment; instead, both biliterate groups resembled English monoliterates in showing a left-to-right, task-dependent SNARC effect, albeit weaker than English monoliterates’. The absence of significant biases in all Arabic-reading groups (biliterates and Arabic monoliterates) points to a potential conflict between distinct spatial-numerical mapping codes. This view is explained in terms of the proposed Multiple Competing Codes Theory (MCCT), which posits three distinct spatial-numerical mapping codes (innate, cardinal, ordinal) during numerical processing—each involved at varying levels depending on individual and task factors.

Paper in Applied Linguistics (Ahn & Chang)
Published:
A paper entitled “Emotion word development in bilingual children living in majority and minority contexts” (Ahn & Chang, 2022) has been published in Applied Linguistics.
Abstract: The lexicon of emotion words is fundamental to interpersonal communication. To examine how emotion word acquisition interacts with societal context, the present study investigated emotion word development in three groups of child Korean users aged 4–13 years: those who use Korean primarily outside the home as a majority language (MajKCs) or inside the home as a minority language (MinKCs), and those who use Korean both inside and outside the home (KCs). These groups, along with a group of L1 Korean adults, rated the emotional valence of 61 Korean emotion words varying in frequency, valence, and age of acquisition. Results showed KCs, MajKCs, and MinKCs all converging toward adult-like valence ratings by ages 11–13 years; unlike KCs and MajKCs, however, MinKCs did not show age-graded development and continued to diverge from adults in emotion word knowledge by these later ages. These findings support the view that societal context plays a major role in emotion word development, offering one reason for the intergenerational communication difficulties reported by immigrant families.

Kpogo in JALL
Published:
PhD student Felix Kpogo just published an article entitled “Acquisition of doubly articulated stops among Ga-speaking children” (Kpogo, Gathercole, & Tetteh, 2021) in the Journal of African Languages and Linguistics!
Abstract: This study investigates the acquisition of labio-velar stops by Ga-speaking children in Ghana. Such stops were elicited in initial, intervocalic, and pre-lateral positions through a picture naming task. Sixty Ga-dominant and Ga-English children at 5-, 6 1/2-, and 8-years of age were tested. All age groups showed some difficulty with the doubly articulated stops, but this was relative to voicing, phonological environment, age, and input. Performance on the voiceless labio-velar stop was better than on the voiced labio-velar stop, and better in intervocalic position than in word-initial and pre-lateral positions. Older children performed better than younger children and Ga-dominant children better than Ga-English children. Performance was better when children did not receive a prompt than when they did. Analysis of modifications reveals frequent processes of simplification to labial singleton stops, some voicing changes, and the occurrence of processes of vowel insertion between the stops and /l/. These findings are discussed in terms of universals of speech sound acquisition, the role of input, and the influence of language-specific factors on children’s performance.

Published:
A review chapter entitled “Phonetics and phonology of heritage languages” (Chang, 2021) has been published in The Cambridge Handbook of Heritage Languages and Linguistics, edited by Profs. Silvina Montrul and Maria Polinsky.
Abstract: This chapter provides an overview of research on heritage language (HL) sound systems, with a focus on areas of convergence and divergence among heritage speakers (HSs), native speakers (NSs) who continue to be dominant in the language, and second language learners (L2ers) who acquired the language later in life. Drawing on data from a wide range of HLs, the chapter addresses both phonetic (articulatory, acoustic, perceptual) and phonological (phonemic, distributional, phonotactic) aspects of the HL sound system, as well as that of the majority language, in light of theories of bilingual speech and variables previously studied as predictors of HSs' linguistic behavior. Despite the diversity of results reviewed, several recurring themes emerge, including intermediate patterning between NSs and L2ers, a higher level of performance in perception than production, and individual variability. In particular, the depth and the accessibility of HSs' knowledge of the HL sound system show considerable variation related to structural linguistic factors, demographic and sociolinguistic factors, input and usage-based factors, and methodological factors. In addition to summarizing the areas in which there is an emerging consensus, the chapter points out a number of remaining questions that pave the way for future research on HL sound systems.

Paper in Languages (Chang & Kwon)
Published:
A paper entitled “The contributions of crosslinguistic influence and individual differences to nonnative speech perception” (Chang & Kwon, 2020) has been published in the “Exploring Cross-linguistic Effects and Phonetic Interactions in the Context of Bilingualism” special issue of Languages, guest-edited by Dr. Mark Amengual.
Abstract: Perception of a nonnative language (L2) is known to be affected by crosslinguistic transfer from a listener’s native language (L1), but the relative importance of L1 transfer vis-a-vis individual learner differences remains unclear. This study explored the hypothesis that the nature of L1 transfer changes as learners gain experience with the L2, such that individual differences are more influential at earlier stages of learning and L1 transfer is more influential at later stages of learning. To test this hypothesis, novice L2 learners of Korean from diverse L1 backgrounds were examined in a pretest-posttest design with respect to their perceptual acquisition of novel L2 consonant contrasts (the three-way Korean laryngeal contrast among lenis, fortis, and aspirated plosives) and vowel contrasts (/o/-/ʌ/, /u/-/ɨ/). Whereas pretest performance showed little evidence of L1 effects, posttest performance showed significant L1 transfer. Furthermore, pretest performance did not predict posttest performance. These findings support the view that L1 knowledge influences L2 perception dynamically, according to the amount of L2 knowledge available to learners at that time. That is, both individual differences and L1 knowledge play a role in L2 perception, but to different degrees over the course of L2 development.

- Michael Fang & Charles B. Chang: “Testing the role of the L1 in L2 connected speech production”
Given previous evidence of crosslinguistic influence (CLI) of the L1 in L2 speech, this study tested the explanatory power of the L1 in accounting for L2 connected speech. Comparing late L2 learners of English from an L1 Mandarin background with L1 English speakers, we examined production of three types of word boundaries in spontaneous connected English speech (nasal-to-vowel, lateral-to-vowel, vowel-to-vowel), perceptually coding each boundary for connectedness and following prominence. Results showed no clear CLI from Mandarin in learners’ connected speech, suggesting that, at least at more advanced stages of L2 development, the L1 plays little to no role in L2 connected speech: disparities between L1 and L2 speakers that would follow from CLI do not occur, while disparities that do occur cannot be explained by CLI. These findings thus highlight the limitations of an L1-based approach and, consequently, the need to engage other explanations for L2 connected speech production.

Chapter in Oxford Handbook of Language Attrition
Published:
A review chapter entitled “Phonetic drift” (Chang, 2019) has been published in The Oxford Handbook of Language Attrition, edited by Profs. Monika Schmid and Barbara Köpke.
Abstract: This chapter provides an overview of research on the phonetic changes that occur in one's native language (L1) due to recent experience in another language (L2), a phenomenon known as phonetic drift. Through a survey of empirical findings on segmental and suprasegmental acoustic properties, the chapter examines the features of the L1 that are subject to phonetic drift, the cognitive mechanism(s) behind phonetic drift, and the various factors that influence the likelihood of phonetic drift. In short, virtually all aspects of L1 speech are subject to drift, but different aspects do not drift in the same manner, possibly due to multiple routes of L2 influence coexisting at different levels of L1 phonological structure. In addition to the timescale of these changes, the chapter discusses the relationship between phonetic drift and attrition as well as some of the enduring questions in this area.
Paper on L3 tone perception in JASA
Published:
A paper entitled “Perception of nonnative tonal contrasts by Mandarin-English and English-Mandarin sequential bilinguals” (Chan & Chang, 2019) has been published in the August issue of the Journal of the Acoustical Society of America. This paper describes the L3 tone perception study presented at BUCLD 42, which was completed as part of the requirements for I Lei (Vicky) Chan’s MA in Applied Linguistics. Congratulations to Vicky on publishing her first peer-reviewed journal article!
Abstract: This study examined the role of acquisition order and crosslinguistic similarity in influencing transfer at the initial stage of perceptually acquiring a tonal third language (L3). Perception of tones in Yoruba and Thai was tested in adult sequential bilinguals representing three different first (L1) and second language (L2) backgrounds: L1 Mandarin-L2 English (MEBs), L1 English-L2 Mandarin (EMBs), and L1 English-L2 intonational/non-tonal (EIBs). MEBs outperformed EMBs and EIBs in discriminating L3 tonal contrasts in both languages, while EMBs showed a small advantage over EIBs on Yoruba. All groups showed better overall discrimination in Thai than Yoruba, but group differences were more robust in Yoruba. MEBs' and EMBs' poor discrimination of certain L3 contrasts was further reflected in the L3 tones being perceived as similar to the same Mandarin tone; however, EIBs, with no knowledge of Mandarin, showed many of the same similarity judgments. These findings thus suggest that L1 tonal experience has a particularly facilitative effect in L3 tone perception, but there is also a facilitative effect of L2 tonal experience. Further, crosslinguistic perceptual similarity between L1/L2 and L3 tones, as well as acoustic similarity between different L3 tones, play a significant role at this early stage of L3 tone acquisition.

Paper on sustained phonetic drift in JPhon
Published:
A research article entitled “Language change and linguistic inquiry in a world of multicompetence: Sustained phonetic drift and its implications for behavioral linguistic research” (Chang, 2019) has been published in the “Plasticity of Native Phonetic and Phonological Domains in the Context of Bilingualism” special issue of Journal of Phonetics, guest-edited by Drs. Esther de Leeuw and Chiara Celata.
Abstract: Linguistic studies focusing on monolinguals have often examined individuals with considerable experience using another language. Results of a methodological review suggest that conflating ostensibly 'multicompetent' individuals with monolinguals is still common practice. A year-long longitudinal study of speech production demonstrates why this practice is problematic. Adult native English speakers recently arrived in Korea showed significant changes in their production of English stops and vowels (in terms of voice onset time, fundamental frequency, and formant frequencies) during Korean classes and continued to show altered English production a year later, months after their last Korean class. Consistent with an Incidental Processing Hypothesis (IPH) concerning the processing of ambient linguistic input, some changes persisted even in speakers who reported limited active use of Korean in their daily life. These patterns thus suggest that the linguistic experience obtained in a foreign language environment induces and then prolongs restructuring of the native language, making the multicompetent native speaker in a foreign language environment unrepresentative of a monolingual in a native language environment. Such restructuring supports the view that one's native language continues to evolve in adulthood, highlighting the need for researchers to be explicit about a population under study and to accordingly control (and describe) language background in a study sample.

Chapter in Routledge Handbook of Phonetics
Published:
A review chapter entitled “The phonetics of second language learning and bilingualism” (Chang, 2019) has been published in The Routledge Handbook of Phonetics, edited by Profs. William Katz and Peter Assmann.
Abstract: This chapter provides an overview of major theories and findings in the field of second language (L2) phonetics and phonology. Four main conceptual frameworks are discussed and compared: the Perceptual Assimilation Model-L2, the Native Language Magnet Theory, the Automatic Selective Perception Model, and the Speech Learning Model. These frameworks differ in terms of their empirical focus, including the type of learner (e.g., beginner vs. advanced) and target modality (e.g., perception vs. production), and in terms of their theoretical assumptions, such as the basic unit or window of analysis that is relevant (e.g., articulatory gestures, position-specific allophones). Despite the divergences among these theories, three recurring themes emerge from the literature reviewed. First, the learning of a target L2 structure (segment, prosodic pattern, etc.) is influenced by phonetic and/or phonological similarity to structures in the native language (L1). In particular, L1-L2 similarity exists at multiple levels and does not necessarily benefit L2 outcomes. Second, the role played by certain factors, such as acoustic phonetic similarity between close L1 and L2 sounds, changes over the course of learning, such that advanced learners may differ from novice learners with respect to the effect of a specific variable on observed L2 behavior. Third, the connection between L2 perception and production (insofar as the two are hypothesized to be linked) differs significantly from the perception-production links observed in L1 acquisition. In service of elucidating the predictive differences among these theories, this contribution discusses studies that have investigated L2 perception and/or production primarily at a segmental level. In addition to summarizing the areas in which there is broad consensus, the chapter points out a number of questions which remain a source of debate in the field today.

Paper on Chinese LexTALE in BUCLD 42 Proceedings
Published:
A paper entitled “LEXTALE_CH: A quick, character-based proficiency test for Mandarin Chinese” (Chan & Chang, 2018) has been published in the Proceedings of the 42nd Annual Boston University Conference on Language Development. This paper describes the development of the Mandarin proficiency test that was used for control purposes in the tone perception study presented at BUCLD 42.
Abstract: Research in second language acquisition suggests that objective performance-based assessments may provide more reliable and valid measures of second language proficiency than subjective self-ratings. To measure proficiency in English as a second language, a quick, vocabulary-based test called LexTALE (Lexical Test for Advanced Learners of English) was developed and shown to be able to differentiate between various levels of English proficiency. Following in the line of adaptations of this test for other languages, we created a character-based adaptation for Mandarin Chinese: LEXTALE_CH. In this paper, we discuss the development and validation of LEXTALE_CH in detail. In short, LEXTALE_CH can discriminate between high and low levels of Mandarin proficiency and is sensitive to the significant differences in vocabulary size between native speakers and second language learners of Mandarin; further, it takes only a few minutes to administer and is simple to score, making it a practical tool for low-stakes estimation of Mandarin proficiency.

Paper on crosslinguistic speech perception in JPhon
Published:
A research article entitled “Perceptual attention as the locus of transfer to nonnative speech perception” (Chang, 2018) has been published in the May issue of Journal of Phonetics.
Abstract: One's native language (L1) is known to influence the development of a nonnative language (L2) at multiple levels, but the nature of L1 transfer to L2 perception remains unclear. This study explored the hypothesis that transfer effects in perception come from L1-specific processing strategies, which direct attention to phonetic cues according to their estimated relative functional load (RFL). Using target languages that were either familiar (English) or unfamiliar (Korean), perception of unreleased final stops was tested in L1 English listeners and four groups of L2 English learners whose L1s differ in stop phonotactics and the estimated RFL of a crucial cue to unreleased stops (i.e., vowel-to-consonant formant transitions). Results were, overall, consistent with the hypothesis, with L1 Japanese listeners showing the poorest perception, followed by L1 Mandarin, Russian, English, and Korean listeners. Two exceptions occurred with Russian listeners, who underperformed Mandarin listeners in identification of English stops and outperformed English listeners in identification of Korean stops. Taken together, these findings support a cue-centric view of transfer based on perceptual attention over a direct phonotactic view based on structural conformity. However, transfer interacts with prior L2 knowledge, which may result in significantly different perceptual consequences for a familiar and an unfamiliar L2.

Paper on perceptual attrition in Language Learning
Published:
A research article entitled “Age effects in first language attrition: Speech perception by Korean-English bilinguals” (Ahn, Chang, DeKeyser, & Lee-Ellis, 2017) has been published in the September issue of Language Learning.
Abstract: This study investigated how bilinguals’ perception of their first language (L1) differs according to age of reduced contact with L1 after immersion in a second language (L2). Twenty-one L1 Korean-L2 English bilinguals in the United States, ranging in age of reduced contact from 3 to 15 years, and 17 control participants in Korea were tested perceptually on three L1 contrasts differing in similarity to L2 contrasts. Compared to control participants, bilinguals were less accurate on L1-specific contrasts, and their accuracy was significantly correlated with age of reduced contact, an effect most pronounced for the contrast most dissimilar to L2. These findings suggest that the earlier bilinguals are extensively exposed to L2, the less likely they are to perceive L1 sounds accurately. However, this relationship is modulated by crosslinguistic similarity, and a turning point in L2 acquisition and L1 attrition of phonology appears to occur at around age 12.

Paper on tone learning aptitude in Language Learning
Published:
A research article entitled “Pitch ability as an aptitude for tone learning” (Bowles, Chang & Karuzis, 2016) has been published in the December issue of Language Learning.
Abstract: Tone languages such as Mandarin use voice pitch to signal lexical contrasts, presenting a challenge for second/foreign language (L2) learners whose native languages do not use pitch in this manner. The present study examined components of an aptitude for mastering L2 lexical tone. Native English speakers with no previous tone language experience completed a Mandarin word learning task, as well as tests of pitch ability, musicality, L2 aptitude, and general cognitive ability. Pitch ability measures improved predictions of learning performance beyond musicality, L2 aptitude, and general cognitive ability and also predicted transfer of learning to new talkers. In sum, although certain nontonal measures help predict successful tone learning, the central components of tonal aptitude are pitch-specific perceptual measures.

Paper on Mandarin tone in Heritage Language Journal
Published:
A research article entitled “Toward an understanding of heritage prosody: Acoustic and perceptual properties of tone produced by heritage, native, and second language speakers of Mandarin” (Chang & Yao, 2016) has been published in the August issue of the Heritage Language Journal.
Abstract: In previous work examining heritage language phonology, heritage speakers have often patterned differently from native speakers and late-onset second language (L2) learners with respect to overall accent and segmentals. The current study extended this line of inquiry to suprasegmentals, comparing the properties of lexical tones produced by heritage, native, and L2 speakers of Mandarin living in the U.S. We hypothesized that heritage speakers would approximate native norms for Mandarin tones more closely than L2 speakers, yet diverge from these norms in one or more ways. We further hypothesized that, due to their unique linguistic experience, heritage speakers would sound the most ambiguous in terms of demographic background. Acoustic data showed that heritage speakers approximated native-like production more closely than L2 speakers with respect to the pitch contour of Tone 3, durational shortening in connected speech, and rates of Tone 3 reduction in non-phrase-final contexts, while showing the highest levels of tonal variability among all groups. Perceptual data indicated that heritage speakers’ tones differed from native and L2 speakers’ in terms of both intelligibility and perceived goodness. Consistent with the variability results, heritage speakers were the most difficult group to classify demographically. Taken together, these findings suggest that, with respect to tone, early heritage language experience can, but does not necessarily, result in a phonological advantage over L2 learners. Further, they add support to the view that heritage speakers are language users distinct from both native and L2 speakers.
This study is a follow-up to Chang, Yao, Haynes, and Rhodes (2011).
Paper on bilingual perception in Bilingualism
Published:
A research article entitled “Bilingual perceptual benefits of experience with a heritage language” (Chang, 2016) has been published in the August issue of Bilingualism: Language and Cognition.
Abstract: Research on the linguistic knowledge of heritage speakers has been concerned primarily with the advantages conferred by heritage language experience in production, perception, and (re)learning of the heritage language. Meanwhile, second-language speech research has begun to investigate potential benefits of first-language transfer in second-language performance. Bridging these two bodies of work, the current study examined the perceptual benefits of heritage language experience for heritage speakers of Korean in both the heritage language (Korean) and the dominant language (American English). It was hypothesized that, due to their early bilingual experience and the different nature of unreleased stops in Korean and American English, heritage speakers of Korean would show not only native-like perception of Korean unreleased stops, but also better-than-native perception of American English unreleased stops. Results of three perception experiments were consistent with this hypothesis, suggesting that benefits of early heritage language experience can extend well beyond the heritage language.
Paper on bilingualism and sound change in Language
Published:
A research article entitled “On the cognitive basis of contact-induced sound change: Vowel merger reversal in Shanghainese” (Yao & Chang, 2016) has been published in the June issue of Language, the journal of the Linguistic Society of America.
Abstract: This study investigates the source and status of a recent sound change in Shanghainese (Wu, Sinitic) that has been attributed to language contact with Mandarin. The change involves two vowels, /e/ and /ɛ/, reported to be merged three decades ago but produced distinctly in contemporary Shanghainese. Results of two production experiments show that speaker age, language mode (monolingual Shanghainese vs. bilingual Shanghainese-Mandarin), and crosslinguistic phonological similarity all influence the production of these vowels. These findings provide evidence for language contact as a linguistic means of merger reversal and are consistent with the view that contact phenomena originate from cross-language interaction within the bilingual mind.

Congrats to Spring 2016 UROP grant recipients
Published:
Congratulations to Jimmy Sbordone and Dallas Walter, who were awarded Undergraduate Research Opportunities Program (UROP) grants to work on research projects in Spring 2016! Below are brief descriptions of the projects they will be working on:
- James Sbordone: "Phonetic description of Southeastern Pomo, an endangered language of California"
Jimmy will be working on an acoustic analysis of recordings of Southeastern Pomo, a severely endangered language historically spoken in northern California. These data will ultimately contribute to a phonetic description of the idiolect of the last living fluent speaker as well as a diachronic comparison between her speech and the speech of the preceding generation (captured on archival recordings).
Paper on tone learning in JASA
Published:
A research article entitled “Context effects on second-language learning of tonal contrasts” (Chang & Bowles, 2015) has been published in the December issue of the Journal of the Acoustical Society of America.
Abstract: Studies of lexical tone learning generally focus on monosyllabic contexts, while reports of phonetic learning benefits associated with input variability are based largely on experienced learners. This study trained inexperienced learners on Mandarin tonal contrasts to test two hypotheses regarding the influence of context and variability on tone learning. The first hypothesis was that increased phonetic variability of tones in disyllabic contexts makes initial tone learning more challenging in disyllabic than monosyllabic words. The second hypothesis was that the learnability of a given tone varies across contexts due to differences in tonal variability. Results of a word learning experiment supported both hypotheses: tones were acquired less successfully in disyllables than in monosyllables, and the relative difficulty of disyllables was closely related to contextual tonal variability. These results indicate limited relevance of monosyllable-based data on Mandarin learning for the disyllabic majority of the Mandarin lexicon. Furthermore, in the short term, variability can diminish learning; its effects are not necessarily beneficial but dependent on acquisition stage and other learner characteristics. These findings thus highlight the importance of considering contextual variability and the interaction between variability and type of learner in the design, interpretation, and application of research on phonetic learning.
