Assessment in Second Language Pronunciation. By O. Kang and A. Ginther (Eds.), London and New York: Routledge, 2018, 190 pp., $39.91 (paperback). ISBN: 978-1-138-85687-5 (pbk)

The pendulum of L2 pronunciation research has swung back to a time when there is a revitalization in research into assessment of second language pronunciation, with two edited volumes published within two years, Isaacs and Trofimovich (2016) and Kang and Ginther (2018), the book reviewed here. Assessment in Second Language Pronunciation takes pronunciation as a crucial aspect of oral production and delves into important constructs like accentedness, intelligibility and comprehensibility and the assessment of these constructs and sub-constructs in international communication and the related validity issues. The volume also discusses application of speech technology in pronunciation assessment, making it a highly-welcomed addition to the literature.
