This study examines the effects of task complexity on second language (L2) pronunciation accuracy and global pronunciation measures in pronunciation-unfocused tasks and assesses the relationship between acoustic and listener-based pronunciation measures. Eighty-two Catalan/Spanish learners of English performed simple and complex versions of a…

Purpose: This study examined spontaneous, spoken-to-a-model, and two sung modes in speakers with Parkinson's disease (PD), speakers with cerebellar disease (CD), and healthy controls. Vocal performance was measured by intelligibility scores and listeners' perceptual ratings. Method: Participants included speakers with hypokinetic dysarthria…

Learners' anxiety has drawn widespread attention in the field of second language/foreign language (L2/FL) teaching and learning (e.g. classroom anxiety, communication (with foreigners) anxiety, and anxiety associated with the four macro-skills, namely listening, reading, speaking, and writing). However, this topic is under-explored in L2/FL public…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

This study examined how mode of input affects the learning of pronunciation and form-meaning connection of second language (L2) words. Seventy-five Japanese learners of English were randomly assigned to 1 of 3 conditions (reading while listening, reading only, listening only), studied 40 low-frequency words while viewing their corresponding…

This study investigates how second language (L2) listeners' perception is affected by two factors: the listeners' experience with the target dialect -- North American English (NAE) vs. Standard Southern British English (SSBE) -- and talkers' language background: native vs. non-native talkers; i.e. interlanguage speech intelligibility benefit…

The current study compared five free Text-To-Speech (TTS) systems, selected based on characteristics such as availability and capabilities. Tasks were completed by 37 English learners to evaluate these systems in terms of their comprehensibility, naturalness, and intelligibility. Our findings indicate that IBM Watson and Google Translate are the…
