Survey Talk: Recognition of Foreign-Accented Speech: Challenges and Opportunities for Human and Computer Speech Communication

Ann R. Bradlow


This presentation will consider the causes, characteristics, and consequences of second-language (L2) speech production through the lens of a talker-listener alignment model. Rather than focusing on L2 speech as deviant from the L1 target, this model views speech communication as a cooperative activity in which interlocutors adjust their speech production and perception in a bi-directional, dynamic manner. Three lines of support will be presented. First, principled accounts of salient acoustic-phonetic markers of L2 speech will be developed with reference to language-general challenges of L2 speech production and to language-specific L1-L2 structural interactions. Next, we will examine recognition of L2 speech by listeners from various language backgrounds, noting in particular that for L2 listeners, L2 speech can be equally (or sometimes, more) intelligible than L1 speech. Finally, we will examine perceptual adaptation to L2 speech by L1 listeners, highlighting studies that focused on interactive, dialogue-based test settings where we can observe the dynamics of talker adaptation to the listener and vice versa. Throughout this survey, I will refer to current methodological and technical developments in corpus-based phonetics and interactive testing paradigms that open new windows on the dynamics of speech communication across a language barrier.
