Purpose: Evidence increasingly indicates that people with developmental stuttering have auditory perception deficits. Our previous research has indicated similar but slower performance in categorical perception of the speech sounds under the quiet condition in children who stutter and adults who stutter (AWS) compared with their typically fluent…

Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…

We investigated how native and fluent users of English segment continuous speech and to what extent they use sound-related and structure-related cues. As suggested by the notion of multi-competence, L1 users are not seen as ideal models with perfect command of English, and L2 users not as lacking in competence. We wanted to see how language…

This study explores the effects of embodied prosodic training on the production of non-native French front rounded vowels (i.e. /y, ø, oe/) and the overall pronunciation proficiency. Fifty-seven Catalan learners of French practiced pronunciation in one of two conditions: one group observed hand gestures embodying prosodic features of the sentences…

Pronunciation is challenging for many international students, but particularly important for those going onto college and university level studies where they need to do professional presentations. According to the Institute of International Education [IIE] (2020), California hosted 160,592 students in 2019/2020, and is one of the top destinations…

The use of linking or glottalization contributes to the characteristic sound pattern of a language, and the use of one in place of the other may affect a speaker's comprehensibility and fluency in certain contexts. In this study, native speakers of Czech, a language that is associated with a frequent use of glottalization in vowel-initial word…

This study critically examined the previously reported partial independence between second language (L2) accentedness (degree to which L2 speech differs from the target variety) and comprehensibility (ease of understanding). In prior work, comprehensibility was linked to multiple linguistic dimensions of L2 speech (phonology, fuency, lexis,…

This study examined the differences in perceptions of the value of feedback for improving English speaking performance between students who received video feedback and those who received written feedback and their preferences for written or video feedback. A total of 43 English as a foreign language students participated in this study to produce a…

High-stakes tasks may prevent language learners from performing successfully due to factors of "communicative stress" (Skehan, 1996, p. 52). Little research, however, has directly examined phonological patterns in learners' performances on low-stakes, medium-stakes, and high-stakes classroom tasks. The current study investigated the oral…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

The current study investigated first language (L1) effects on listener judgment of comprehensibility and accentedness in second language (L2) speech. The participants were 45 university-level adult speakers of English from three L1 backgrounds (Chinese, Hindi, Farsi), performing a picture narrative task. Ten native English listeners used…

Temporal control has often been suspected to be a critical factor in intonation production. In particular, disturbance in the production of fundamental frequency (F0) associated with intonation in patients with aphasia has been attributed to a primary underlying deficit in speech timing. The present study examined the speech timing abilities of…

If the non-native teacher of English as a foreign language hopes to approach a high standard of oral competence in the language, he must cultivate some conscious perception and control of intonation. He can achieve this objective in various ways. Situations in which natural speech occurs would be ideal but few teachers have the opportunity for…
