Articulatory Behaviors of Nonnative Speakers: Role of L2 Proficiency and Accent Modification

Abstract

To sound native-like, nonnative speakers need to approximate the articulatory patterns of native speakers. When nonnative speakers deviate from native speakers' production patterns, it gives rise to a nonnative accent. This study examines how proficiency in a second language (L2) is related to processing skills in L2, as measured by the accuracy of consonant production. 10 monolingual speakers of American English, 10 Bengali-English bilinguals with high proficiency in English, and 10 Bengali-English bilinguals with low proficiency in English participated. The participants spoke 16 nonwords of four different syllable lengths. Productions were phonetically transcribed. Results suggested that nonnative speakers' L2 proficiency differentially interacted with overall phonemic accuracy, usage of appropriate place, manner and voicing features, position of consonants within target words, and syllable length. Implications of these findings are discussed in light of customized strategies for modification of nonnative accents.
