Series: Innovations in Language Learning and Assessment at ETS

Automated Speaking Assessment: Using Language Technologies to Score Spontaneous Speech provides a thorough overview of state-of-the-art automated speech scoring technology as it is currently used at Educational Testing Service (ETS). Its main focus is related to the automated scoring of spontaneous speech elicited by TOEFL iBT Speaking section items, but other applications of speech scoring, such as for more predictable spoken responses or responses provided in a dialogic setting, are also discussed. The book begins with an in-depth overview of the nascent field of automated speech scoring—its history, applications, and challenges—followed by a discussion of psychometric considerations for automated speech scoring. The second and third parts discuss the integral main components of an automated speech scoring system as well as the different types of automatically generated measures extracted by the system features related to evaluate the speaking construct of communicative competence as measured defined by the TOEFL iBT Speaking assessment. Finally, the last part of the book touches on more recent developments, such as providing more detailed feedback on test takers’ spoken responses using speech features and scoring of dialogic speech. It concludes with a discussion, summary, and outlook on future developments in this area. Written with minimal technical details for the benefit of non-experts, this book is an ideal resource for graduate students in courses on Language Testing and Assessment as well as teachers and researchers in applied linguistics.

This book is a landmark volume that provide a comprehensive synthesis of work on automated speech assessment over the past 20 years at Educational Testing Services. The book compiles vital viewpoints, theories, applications, and knowledge from assessment specialists, linguists, computer scientists, and statisticians to provide an engaging and approachable introduction to a dense and innovative field of study that has direct and important implications for language assessment and natural language processing. The book will find a warm welcome in university classrooms, researchers' bookshelves, and libraries for years to come by providing essential knowledge that will help new and experienced readers immerse themselves in automated speech assessment. The individual chapters provide important methodological advances, data analysis approaches, best-practice, and clear interpretations that will help move speech assessment into the next generation. The book fills an important gap by connecting automated speech technology, natural language processing, and statistical learning with applied speech assessment.
