Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

This study aimed to investigate the role that phonetic convergence plays in the acquisition of L2 segments. In particular, it examined whether phonetic convergence towards native speakers could help Arabic-speaking second-language (L2) learners of English improve their pronunciation of four problematic English segments (/p, v, [open-mid front…

Factors that affect comprehension of accented English (e.g., Harding, 2011) have been well studied, but little research examines how listeners' proficiency affects their sensitivity to second language (L2) accent. The current study investigated the effect of test takers' English proficiency on their comprehension ratings and ability to correctly…

This study investigates how second language (L2) listeners' perception is affected by two factors: the listeners' experience with the target dialect -- North American English (NAE) vs. Standard Southern British English (SSBE) -- and talkers' language background: native vs. non-native talkers; i.e. interlanguage speech intelligibility benefit…

Over the past few decades, there has been considerable effort to find the mechanisms through which adult listeners can accommodate the rampant phonetic variation in natural speech. My dissertation concerns one source of variability: phonetic variation in speech produced by individuals with foreign accents. Mounting evidence shows that listeners…

English has assumed a new role in international communication in recent decades, that is, as a Lingua Franca (ELF) among speakers with different first languages. This study attempts to investigate and analyze Chinese university students' perception and production of paired English fricatives from the perspective of ELF. By using a listening…
