This digest reviews the current status of pronunciation instruction in adult English-as-a-Second-Language (ESL) classes. The current focus on communicative approaches to ESL instruction and the concern for building teamwork and communication skills in an increasingly diverse workplace are renewing interest in the role that pronunciation plays in adults' overall communicative competence. As a result, pronunciation is emerging from its often marginalized place in adult ESL instruction. Separate sections of the Digest highlight the history of pronunciation instruction, factors influencing pronunciation mastery, language features involved in pronunciation, incorporating pronunciation in the curriculum, and incorporating pronunciation in instruction.
