This article reviews research findings involving visual input in speech processing in the form of facial cues and co-speech gestures for second-language (L2) learners, and provides pedagogical implications for the teaching of listening and speaking. It traces the foundations of auditory-visual speech research and explores the role of a speaker's…

We propose a new framework for conceptualizing measures of instructed second language (L2) pronunciation performance according to three sets of parameters: (a) the constructs (focused on global vs. specific aspects of pronunciation), (b) the scoring method (human raters vs. acoustic analyses), and (c) the type of knowledge elicited (controlled vs.…

This study focuses on the development of L2 prosody and, in particular, whether different aspects can affect each other. Finnish-speaking learners of Swedish took part in a pronunciation and oral skills course and were recorded for various speaking tasks before and after the experimental intervention. Read-aloud declarative sentences (statements)…

Rhetorical word stress has been identified as a feature of public, presentational, and didactic speech styles in Spanish through theoretical descriptions, intuitive accounts, and laboratory-based empirical research. Most scholars agree that non-primary stress is acoustically marked by pitch and primary stress is marked by segment lengthening. The…

We examine the ability of supervised text classification models to identify several discourse properties from teachers' speech with an eye for providing teachers with meaningful automated feedback about the quality of their classroom discourse. We collected audio recordings from 28 teachers from 10 schools in 164 authentic classroom sessions,…

Though research has shown that rhythmic training is beneficial for phonological speech processing, little empirical work has been carried out to assess whether rhythmic training in the classroom can help to improve pronunciation in a second language. This study tests the potential benefits of hand-clapping to the rhythm of newly learned French…

Purpose: Research has shown that observing hand gestures mimicking pitch movements or rhythmic patterns can improve the learning of second language (L2) suprasegmental features. However, less is known about the effects of hand gestures on the learning of novel phonemic contrasts. This study examines (a) whether hand gestures mimicking phonetic…

The current study examined in depth the effects of suprasegmental-based instruction on the global (comprehensibility) and suprasegmental (word stress, rhythm, and intonation) development of Japanese learners of English as a foreign language (EFL). Students in the experimental group (n = 10) received a total of three hours of instruction over six…
