Purpose: This meta-analysis study aimed to determine the optimal level of talker variability in training to maximize second-language speech learning. Method: We conducted a systematic search for studies comparing different levels of talker variability in nonnative speech training, published through July 2024. Two independent reviewers screened…

Many secondary school students' second language (L2) speaking skills suffer from deficiencies; the effects thereof are detrimental to their academic and career opportunities in a globalized world that highlights the importance of oral communication skills. Debate has been considered a potentially effective speaking pedagogical tool that can…

Without data on speech accuracy of Vietnamese-English speakers, speech-language pathologists (SLPs) are unable to assess accurately this population for speech sound disorders. This study explored the heretofore uninvestigated speech accuracy and use of Vietnamese-English bilingual individuals residing in the USA. Participants included six…

Purpose: Bilingual children often demonstrate a high rate of disfluencies, which might impact the diagnostic evaluation of fluency disorders; however, research on the rates and types of disfluencies in bilinguals' two languages is limited. The purpose of this research is to profile disfluencies of two types, stuttering-like disfluencies (SLDs) and…

Research on the factors influencing the acceptance of GenAI in language learning has expanded widely; however, few studies have focused on the role of language learning emotions. To enhance the effectiveness of GenAI-powered English-speaking instruction and the learning experience, this study expands on the Integrated Model of Technology…

Recent years have witnessed the growing presence of artificial intelligence in language learning apps. Against this backdrop, this technology review provides an overview of the affordances of Speeko and discusses its potential in developing English-as-a-foreign-language students' public speaking skills.

Automatic Speech Scoring (ASS) has increasingly become a useful tool in oral proficiency testing for Second Language (L2) learners. However, limited studies investigate the alignment of ASS indices with the Complexity, Accuracy, and Fluency (CAF)--the three dimensions in evaluating L2 speakers' oral proficiency, and the subsequent impact indices…

This study aims to investigate the VOT values of English wordinitial plosive consonants produced by young Thai learners to understand current trends in English pronunciation among Thai speakers and its future direction. The study analyzes how phonological mismatches between Thai and English affect the pronunciation of Thai learners, using a speech…

The goal of this dissertation is to better understand the targets of vowels in speech production. Three experiments investigate vowel production in non-native speech, probing how new vowel categories, and thus targets, are formed. Three research questions are addressed: (1) Do vowels have articulatory targets (as predicted by Browman &…

The significance of producing socially appropriate utterances, not just linguistically correct ones, has given rise to a plethora of studies on speech acts. In this regard, the performance of second and foreign language learners against the norms of the target language and the factors affecting them have yet to be thoroughly investigated. To…

Drawing on recent scholarship integrating usage-based linguistics (UBL) and conversation analysis (CA) in the investigation of second language development, this paper reports on a microanalysis tracing one adult learner's recurring, increasingly frequent, and diverse use of the multiword expression "det er sant" (it/that is true) (DES)…

Although the ability to speak is often considered a determining factor of learners ability in the target language, research has given scant attention to strategies that can be used to improve this skill. This study aimed to shed light on the speaking strategies that learners use to deal with problems they encounter when using the target language…

Educational speaking technology is a digital expertise used to enhance speaking performance. This research examined the effects of using educational speaking technology tools: FORVO, YouGlish, and OALD 8th ed. to enhance students' speaking performance. A quasi-experimental pretest-posttest two groups design was used. Test, questionnaire,…

The recent world pandemic has highlighted the need for effective procedures to teach language in Computer Assisted Language Learning (CALL) environments. Fully online and asynchronous classrooms are especially challenged when addressing learning to speak a foreign language toward greater communicative competence. Current CALL research is…

The purpose of the study is to investigate the types of corrective feedback used by a Thai teacher with adult learners of different proficiency levels in speaking classes in order to facilitate students' language development, as it is an aspect language teachers need to be aware of when teaching speaking. Three different levels of speaking classes…
