Listeners selectively tune in to the most relevant cues for contrasting sounds, and this process impacts their perceptual sensitivity to these cues (Nosofsky, 1986; Pisoni, 1991). For bilingual listeners, recent work suggests a shared L1/L2 phonology system with the phonetic properties of each sound established in a language-specific way…

This article discusses the implications of phonological representation for the study of L2 speech acquisition. It is argued, on the basis of empirical findings from diverse phenomena in L2 phonology, that refined representations in which 'segments' have internal prosodic structure offer a more insightful view of cross-linguistic phonetic…

Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

This dissertation investigated the acoustic and articulatory correlates of lexical stress in Mandarin second language (L2) learners of English, as well as in first language (L1) speakers. The present study used a minimal pair respective to stress location (e.g., OBject versus obJECT) obtained from a publicly available Mandarin Accented English…

While much research has examined second language (L2) phonetic acquisition, less research has examined first language (L1) attrition in terms of the voice onset time (VOT) of voiceless stops. The current study examined L2 acquisition and L1 attrition in the VOT of word-initial voiceless stops among late English-Arabic and Arabic-English bilinguals…

Mandarin speakers tend to adapt intervocalic nasals as either an onset of the following syllable (e.g. Bruno [right arrow] "bù.lu.nuò"), as a nasal geminate (e.g. Daniel [right arrow] "dan.ní.er"), or as one of the above forms (e.g. Tiffany [right arrow] "dì.fú.ní" or "dì.fen.ní"). Huang and Lin (2013, 2016)…

The study investigates the relationship between lexical encoding and production in order to establish whether learners are able to produce a difficult contrast in words that they merged in their mental lexicon. Forty American English learners of Russian were tested on their production and lexical encoding of familiar and highly-frequent words with…

Successful listening in a second language (L2) involves learning to identify the relevant acoustic-phonetic dimensions that differentiate between words in the L2, and then use these cues to access lexical representations during real-time comprehension. This is a particularly challenging goal to achieve when the relevant acoustic-phonetic…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Lexical tone is a linguistic feature which can present difficulties for second language learners wanting to revitalize their heritage language. This is true not only from the standpoint of understanding and pronunciation, but also because tone is often under-documented and resources are limited or too technical to be useful to community members.…

In two artificial grammar learning experiments, we tested the learnability of tonal phonotactics forbidding non-domain-final rising tones (*NonFinalR) against the phonotactics banning non-domain-final high-level tones (*NonFinalH). We propose that a firm phonetic ground drives a presumably innate inductive bias favoring *NonFinalR and against…

This dissertation documents a collection of sociolinguistic and sociophonetic studies of the speech of bilingual Korean Americans in California. Korean Americans are an ethnic minority in the United States whose speech patterns in Korean and English remain understudied. The goal of the studies is to begin sketching out the acoustic traits that…

This study investigates the acoustic characteristics of Thai tones produced by Chinese students learning Thai through the "Tone Application", and conducts an attitude test towards the use of the Tone Application. A comparison of Thai tones pronounced by the participants with 40 native Thai speakers was also conducted. The acoustic…

This paper examines whether a web-based training on English discourse intonation leads to better spontaneous speech quality for Mandarin Chinese speakers who reside in the U.S. and in China. The four-week fully online training consisted of meta-instruction videos as well as listening and speaking activities, including instant visual pitch contour…

This paper creates a novel link between research on linguistics and education by discussing what we know about the sound system of heritage language users of Spanish and how these findings can inform practices implemented in heritage Spanish courses in the USA. First, we provide an overview of terminology associated with heritage language…
