This book is open access under a CC BY licence. It spans the areas of assessment, second language acquisition (SLA) and pronunciation and examines topical issues and challenges that relate to formal and informal assessments of second language (L2) speech in classroom, research and real-world contexts. It showcases insights from assessing other skills (e.g. listening and writing) and highlights perspectives from research in speech sciences, SLA, psycholinguistics and sociolinguistics, including lingua franca communication, with concrete implications for pronunciation assessment. This collection will help to establish commonalities across research areas and facilitate greater consensus about key issues, terminology and best practice in L2 pronunciation research and assessment. Due to its interdisciplinary nature, this book will appeal to a mixed audience of researchers, graduate students, teacher-educators and exam board staff with varying levels of expertise in pronunciation and assessment and wide-ranging interests in applied linguistics.

Intelligibility has been widely regarded as an appropriate goal for second language pronunciation teaching. Yet there is no universal definition of intelligibility, nor a field-wide consensus on how to best measure it. Further, there is little empirical evidence to suggest which pronunciation features are most critical for intelligibility. This mixed methods study investigates whether intelligibility is an appropriate criterion for assessing pronunciation proficiency in the academic domain. Speech samples of 19 non-native speaking graduate students were elicited using the TSE, a standardized spoken proficiency test often used to screen international teaching assistants. Results of a fined-grained analysis of the speech data coupled with intelligibility ratings of 18 undergraduate students suggest that intelligibility, though an adequate assessment criterion, is a necessary but not a sufficient condition for graduate students to instruct undergraduate courses. The insights offered by this empirical study and state-of-the art introduction on intelligibility are pertinent to anyone with an interest in spoken language assessment, pronunciation pedagogy, or mixed methods research.
