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…

Developing L2 learners' productive mastery of vocabulary is a challenging task. Recent research has called for greater attention to understanding how receptive vocabulary may be transformed for productive use (Schmitt, 2019). Using a design-based research methodology, this study investigated adult ESL learners' productive oral vocabulary…

Our study proposes the use of a free classification task for investigating the dimensions used by listeners in their perception of nonnative sounds and for predicting the perceptual discriminability of nonnative contrasts. In a free classification task, participants freely group auditory stimuli based on their perceived similarity. The results can…

This research was aimed at investigating L1 Thai learners' English word stress production in two aspects of English words -- 1) English words with different suffixes: suffixes affecting stress shift, i.e. '-ic' (e.g. 'fantástic'), '-ity' (e.g. 'idéntity') and '-tion / -sion' (e.g. 'eléction') and suffixes demanding stress, i.e. '-oon' (e.g.…

Language ideologies are a powerful way of perpetuating inequalities, as peripheralized speakers who have internalized the lack of legitimacy attributed to them often end up reproducing censure rather than resisting it. Foregrounding the affective dimension, this paper explores the role of shame as a fulcrum articulating the individual with the…

Korean learners of English are known to repair consonant clusters, which are not allowed in their native language, with an epenthetic vowel [close central unrounded vowel]. The purpose of the present study is to examine whether the perception-production link of such an illusory vowel in a second language (L2) is only within and not across…

Pairing affect theory with raciolinguistic perspectives, this study examines the racialized and embodied identities of second-generation Chinese American heritage language learners. Drawing on the data collected through in-depth interviews, the study observes that second-generation Chinese Americans' affective experiences, such as their racialized…

Upon hearing someone's speech, a listener can access information such as the speaker's age, gender identity, socioeconomic status, and their linguistic background. However, an open question is whether living in different locales modulates how listeners use these factors to assess speakers' speech. Here, an audio-visual test was used to measure…

Pronunciation instruction has historically been notorious for its intense reliance on repetition practice and mechanical drilling across most foreign and second language settings. However, research indicates that form-focused instruction can be substantially beneficial to the development of phonological skills (Saito, 2012). The current…

Purpose: Speech production deficits and reduced intelligibility are frequently noted in individuals with Down syndrome (DS) and are attributed to a combination of several factors. This study reports acoustic data on vowel production in young adults with DS and relates these findings to perceptual analysis of speech intelligibility. Method:…

Availability of orthography during word learning has been found to facilitate learning the word's spelling and pronunciation and has been proposed to facilitate learning its meaning. This has not been studied in second language (L2) learning yet, in which word learning often corresponds to translation learning. Therefore, an L2 word learning…

In this article, we examine the hierarchization of international students by bringing together perspectives of linguistic legitimacy and language ideologies. Our data stems from 26 accent reduction or accent modification course descriptions and websites from U.S. universities. Based on their analysis, we discuss the sociopolitical implications of…

A phoneme-detection task shows that listeners of Sepedi use semantic information in processing but not prosody (Experiment 1). Sepedi is a language with no grammaticalised prosodic expression of focus. Sepedi listeners detected phoneme targets faster when the phoneme-bearing words were focussed (as opposed to unfocussed) but not when occurring in…

This article employs a language ideological framework to explore how particular language attitudes and beliefs shaped one group of U.S. students' choices to avoid producing a dialectal variant, Castilian Spanish [theta], in the context of an undergraduate Spanish pronunciation class. An analysis of ethnographic data points to the significance of…

Speech is extremely variable along many different dimensions. One source of variability listeners often encounter is accented speech, in which phonological units can systematically differ from the listener's native categories. This dissertation presents five experiments testing how listeners adapt to accent-based phonological variability,…
