Dialects vary in their allophonic patterns, which can affect listeners' phonological and lexical representations. I explore how different exposure to dialect-specific allophonic patterns for two vowels in American English, /ae ai/, affects listeners' lexical processing behaviors across three perception tasks: perceptual similarity, priming, and…

During spoken word processing, native (L1) listeners use allophonic variation to predictively rule out word competitors and speed up word recognition. There is some evidence that second language (L2) learners develop an awareness of allophonic distributions in their L2, but whether they use their knowledge to facilitate word recognition online,…

Adult learners acquire second language (L2) allophones with experience. We examine two mechanisms which may support the acquisition of allophonic variants in second language acquisition. One of the mechanisms is based on the distribution of phones with respect to their phonological context (i.e. phonological distribution). The other is based on…

Listeners use more than just acoustic information when processing speech. Social information, such as a speaker's race/ethnicity, can also affect listeners' understanding of the speech signal. In some cases, these social primes can facilitate perception, while in others they may inhibit perception. Indeed, a picture of an East Asian face has been…

Successful word recognition requires that listeners attend to differences that are phonemic in the language while also remaining flexible to the variation introduced by different voices and accents. Previous work has demonstrated that American-English-learning 19-month-olds are able to balance these demands: although one-off one-feature…

In this paper, the researcher aims at investigating and revisiting the impact of Krashen's input hypothesis on L2 output. Based on Krashen's theories, the researcher proposes the homogeneity hypothesis as an extension to the input hypothesis. Homogeneity hypothesis states that the linguistic input given to L2 learners should be not only…

During conversation, talkers may adapt their speech in a variety of ways. One form of speech adaptation is clear speech, in which a talker selectively hyperarticulates segments when faced with specific communication challenges. The present speech production experiment investigated how talkers adapt a common feature of American English dialects:…

Infants struggle to understand familiar words spoken in unfamiliar accents. Here, we examine whether accent exposure facilitates accent-specific adaptation. Two types of pre-exposure were examined: video-based (i.e., listening to pre-recorded stories; Experiment 1) and live interaction (reading books with an experimenter; Experiments 2 and 3).…

This study examined Americans' attitudes toward standard American English (SAE) and nine, non-Anglo foreign accents: Arabic, Farsi, French, German, Hindi, Hispanic, Mandarin, Russian, and Vietnamese. Compared to SAE speakers, all foreign-accented speakers were rated as harder to understand, more likely to be categorised as foreign (rather than…

This study investigated the developmental trajectories of three perceptual domains related to regional dialect competence: the linguistic domain, tested through an intelligibility in noise task; the objective indexical domain, tested through locality judgments and a free classification task; and the subjective indexical domain, tested through…

Syntactic priming studies in second language (L2) have contributed to understanding how L2 speakers' syntactic knowledge is represented and processed. However, little is known about social influences on L2 speakers' syntactic processing and learning. The present study investigated whether L2 speakers' syntactic priming is influenced by social…

Purpose: The language processing of Mandarin-accented English (MAE) by older hearing-impaired (OHI), older normally hearing (NH), and younger NH listeners was explored. We examined whether OHI adults have more difficulty than NH listeners in recognizing and adapting to MAE speech productions after receiving brief training with the accent. Method:…

Language exposure plays a large role in language acquisition, and bilingual children must acquire both of their languages in environments that typically include abundant speech variability. The specific goals of this dissertation were to examine how speech exposure affected phonological retuning and lexical access in bilingual children's second…

This study explores the most perceivable phonological features of Hong Kong (HK) L2 English speakers and how they affect the perception of HK L2 English speech from the perspective of both native and non-native English listeners. Conversational interviews were conducted to collect speech data from 20 HK speakers of English and 10 native speakers…

This article proposes a model for integrating text-to-speech software (TTS) in students' interpreting training and practice. It shows the aims of the model, the definition of TTS, the advantages of using TTS, how to search for TTS, instructional stages with TTS, and the interpreting instructor's role. The students can use TTS software online;…
