9. Computer Technology in Teaching and Researching Pronunciation

Pronunciation, long on the periphery of applied linguistics research and pedagogy, continues to grow in importance because of its central roles in speech recognition, speech perception, and speaker identity. Pronunciation-related issues such as comprehensibility, accent, and the mutual intelligibility of varieties of world Englishes are central to many questions in applied linguistics. This calls for a sophisticated understanding of how technological tools that have long been used to shed light on phonological categories can be applied to teaching. Research into computer-assisted pronunciation teaching (CAPT) suggests that both researchers and pronunciation teachers increasingly make use of technology to answer key questions, to ensure that claims are defensible, and to develop theories and practices that more closely match acoustic reality. This article reviews three key areas where computer technology and pronunciation intersect: (1) appropriate pedagogical goals and the measurement of improvement; (2) the ability of CAPT to give useful, automatic feedback; and (3) the use of technology in diagnosing pronunciation errors. This article concludes with recommendations for key technological competencies needed by any researcher or teacher who examines pronunciation-related issues.
