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…

An increasing number of studies are exploring the benefits of automatic speech recognition (ASR)-based dictation programs for second language (L2) pronunciation learning (e.g. Chen, Inceoglu & Lim, 2020; Liakin, Cardoso & Liakina, 2015; McCrocklin, 2019), but how ASR recognizes accented speech and the nature of the feedback it provides to…

Published in "Language Learning" in 1995, Munro and Derwing's* investigation of foreign accent, comprehensibility, and intelligibility in second language (L2) speech instigated significant change in L2 pronunciation research (Levis, 2020). A key finding was that despite the presence of a foreign accent, listeners could indeed comprehend…

Comprehensibility, or ease of understanding, has emerged as an important construct in second language (L2) speech research. Many studies have examined the linguistic features that underlie this construct, but there has been limited work on behavioral and affective predictors. The goal of this study was therefore to examine the extent to which…

This report examines the potential impacts of task and proficiency on listener judgments of intelligibility, comprehensibility, and accentedness in L2 Spanish. This study extends Huensch and Nagle ["Language Learning," 71, 626-668, (2021)], who explored the partial independence among the global speech dimensions for speech samples taken…

Although current approaches to second language (L2) pronunciation underscore that instruction should concentrate on pronunciation features that help learners be more intelligible (and not necessarily more native like), there is little empirical evidence as to what those features are, especially in languages other than English. To address this gap,…

This dissertation deals with the perception of the aspirated coda /s/ by Spanish L2 learners. Second language research, with some exceptions, focuses on whether L1English-L2 Spanish learners can perceive the aspirated variant, showing that only advanced learners with time spent in s-weakening regions succeed at the task. L2 studies about…

To examine speaker role models (SRMs) in second language acquisition (SLA), this study explored the sociolinguistic "English as a lingua franca" (ELF) perspective targeting international intelligibility. Thus, it examined the way ELF learners align with self-selected English speakers and anonymous (audio-recorded) English speakers as…

This study aimed to answer an ongoing validity question related to the use of nonstandard English accents in international tests of English proficiency and associated issues of test fairness. More specifically, we examined (1) the extent to which different or shared English accents had an impact on listeners' performances on the Duolingo listening…

This controlled experimental study investigated the interaction of variables associated with rating the pronunciation component of high-stakes English-language-speaking tests such as IELTS and TOEFL iBT. One hundred experienced raters who were all either familiar or unfamiliar with Brazilian-accented English or Papua New Guinean Tok Pisin-accented…

As there is a growing population of non-native speakers worldwide, facilitating communication involving native and non-native speakers has become increasingly important. While one way to help communication involving native and non-native speakers is to help non-native speakers improve proficiency in their target language, another way is to help…

The purpose of this study was to explore the effect of the listener's education and occupation on intelligibility, comprehensibility (ease of understanding), and accentedness in speakers of Russian-accented American English (RA), Southern-accented American English (SA), and General American English (GAE). Native English listeners (N=126) rated…

Research on intelligibility in international encounters has long focused on issues of pronunciation to the detriment of factors such as linguistic co-text and extralinguistic context, which are comparatively well-studied variables in intelligibility research concerning L1 listeners. This paper seeks to expand the scope of international…

This paper provides a research synthesis of intelligent personal assistants (IPAs) -- that is, cloud-based virtual assistants such as Alexa, Google Assistant, and Siri -- for second language (L2) learning. The article also offers a theoretical justification for the use of IPAs in language learning and outlines the affordances and constraints of…

This study examines L2 speakers' accent attitudes in relation to their linguistic profile and current practices, recruiting 107 multilingual postgraduate students of 34 different nationalities enrolled in leading research universities in Japan. The participants completed a survey regarding their perceptions of different English varieties in…
