Purpose: Speech disfluencies are common in individuals who do not stutter, with estimates suggesting a typical rate of six per 100 words. Factors such as language ability, processing load, planning difficulty, and communication strategy influence disfluency. Recent work has indicated that bilinguals may produce more disfluencies than monolinguals,…

Second language (L2) utterance fluency is crucial for speaking proficiency assessment. The measurement of L2 utterance fluency relies heavily on silent pause identification. However, empirical studies establishing specific silent pause thresholds for L2 monologic speaking are scarce, and even fewer exist for L2 dialogic speaking. This study thus…

Purpose: Bilingual children's speech often contains high percentages of disfluencies in both their languages; however, the distribution of disfluency types and the difference across bilinguals' two languages have received insufficient and inconsistent empirical support. The present research aims to profile "typical" bilingual disfluency…

This cross-sectional study examines the sociopragmatic use of pitch and fluency features in requests among second language (L2) Chinese learners at two proficiency levels alongside native Chinese speakers. Twenty-eight L2 learners completed a 40-item oral discourse task with two types of request-making situations: (a) a high-imposition request to…

The relationship between foreign language anxiety (FLA) and foreign language enjoyment (FLE) experienced during a creative collaborative oral English-as-a-foreign-language task, and the relationships between FLE/FLA and task speech fluency were investigated. The task was performed by mid-intermediate/high-intermediate English learners (N = 43) in…

English is especially challenging for English second language (ESL) learners because of its significant cultural and societal implications. For example, idioms--multiworded expressions with multiple meanings--are problematic for ESL learners because of ambiguity in literal translation and reliance on the societal context. This quantitative…

Current L2 utterance fluency literature tends to operationalize disfluency as isolated, individual features. However, disfluency features often co-occur at one location or across multiple locations in one utterance. This study explores the co-occurrence of L2 disfluency features in a speech corpus from 71 L1 and L2 speakers of English across…

Background/purpose: Despite its informal setting, it is astonishing that the members of online English-speaking club (ESC) are adept at speaking. Employing a mixed-methods approach, more specifically a descriptive case study, this study aimed to evaluate the ESC contribution to its members' speaking competence development, to examine their…

This quasi-experimental study investigated the impacts of two instructional conditions on the fluency of learners' performance. In the first condition (strategy training), learners were provided with explicit fluency strategy training for a portion of each lesson before rehearsing versions of the speaking task for the remainder of the lesson. In…

In semantic fluency tasks, participants employ semantic search strategies (clustering and switching) to facilitate word retrieval. Clustering involves producing sequences of related words, while switching refers to shifting between different semantic categories. Analyzing these strategies provides insights into the structure of the mental lexicon…

Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency. While many studies have established links between these lexical…

This study investigates the impact of Filipina domestic workers (FilDWs), a marginalized group in Hong Kong (HK), on HK children's language development. It focusses on FilDWs' influence on the second language (L2) English of bilingual HK primary school children attending an English Medium of Instruction school. The elements investigated are L2…

This research was conducted to investigate AI integration in the development and evaluation of English oral communication skills, within both academic and professional practices. This study used a mixed-methods design, combining data from a quasi-experiment with qualitative data collected through interviews with students and instructors. Results…

Human-Machine Interaction (HMI) technology has revolutionized the landscape of oral English education, offering new possibilities for improving learning efficiency and experiences. This paper presents an innovative teaching system that integrates real-time speech recognition and feedback capabilities with advanced natural language processing (NLP)…

Amid globalization, the demand for English oral proficiency continues to grow. This study employs a quasi-experimental design to investigate the integration of an AI chatbot into the mobile-assisted blended learning (MABL) framework. It examines the impact of this approach on the spoken English abilities of Chinese non-English major university…
