Purpose: Stuttering-like disfluencies (SLDs) and typical disfluencies (TDs) are both more likely to occur as utterance length increases. However, longer and shorter utterances differ by more than the number of morphemes: They may also serve different communicative functions or describe different ideas. Decontextualized language, or language that…

The importance of vocabulary when speaking is not only demonstrated in models of second language speech production and speaking proficiency but also reflected in rating criteria and assessment scales. The present study examined and compared micro-level lexical information in a speaking task from two complementary stakeholders' perspectives…

Background: While automatic speech recognition (ASR) is increasingly used for commercial purposes, its influence on the learners' linguistic performance in terms of oral complexity, accuracy and fluency was under-explored. To date, few studies have been conducted to investigate how the dictation ASR technology could be incorporated into language…

In current research into second language (L2) speaking, aspects of fluency are measured as static constructs. Averaged over a complete speaking performance, for instance, syllables per minute is calculated. Similarly, the number of pauses is calculated per minute, averaged over a complete speaking task. This paper argues, however, that we need to…

Second language (L2) learners hold different learning beliefs that influence their interpretation of classroom experiences and their L2 learning process. Developing a thorough understanding of such beliefs is therefore imperative. This article reports the representations of Iranian English-as-a-foreign-language (EFL) learners' beliefs about L2…

Purpose: Although commonly defined as a speech disorder, stuttering interacts with the language production system in important ways. Our purpose is to summarize research findings on linguistic variables that influence stuttering assessment and treatment. Method and Results: Numerous topics are summarized. First, we review research that has…

From 2016 to 2022, the "Journal of Applied Behavior Analysis" published 7 studies that evaluated the effects of habit reversal training on speech disfluencies (filled pauses) during public speaking. This review summarizes the participants, dependent variables, procedures, experimental design, and outcomes from this research including…

Teaching speaking skills to EFL learners remains a significant challenge, often hindered by traditional methods that prioritize rote learning over meaningful communication. This study investigates the impact of communicative language teaching (CLT) on the speaking skills of Grade 12 students, while also exploring their attitudes toward this…

Purpose: Extemporaneous speech tasks provide an ecologically valid sample to examine speech acoustics, but differing methodologies exist in the literature for segmentation. Therefore, the purpose of this study was to examine the utility and reliability of a segmentation approach for extemporaneous speech specified by systemic functional…

Purpose: Previous studies have shown that individuals who stutter exhibit abnormal speech perception in addition to disfluent production as compared with their nonstuttering peers. This study investigated whether adult Chinese-speaking stutterers are still able to use knowledge of statistical regularities embedded in their native language to…

The fluency of second language (L2) speech can be influenced by L2 proficiency, but also by differences in the efficiency of cognitive operations and personal speaking styles. The nature of cognitive fluency is still, however, little understood. Therefore, we studied the cognitive fluency of Finnish advanced students of English (N = 64) to…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

Background: Previous studies on language production in normal ageing have primarily focused on distinct dimensions of older adults' spoken language performance, such as fluency and complexity. However, little attention has been paid to the complex, interconnected relations between these dimensions. Additionally, older adults have been treated as a…

Language learning activities involving time-pressured repetition of similar content have been shown to facilitate improvements in fluency. However, concerns have been voiced about whether these gains might be offset by reduced levels of grammatical accuracy. This descriptive study tracked the oral proficiency of 32 Japanese university students…

Purpose: Verbal fluency tasks assess the ability to quickly and efficiently retrieve words from the mental lexicon by requiring subjects to rapidly generate words within a phonological or semantic category. This study investigated differences between cochlear implant users and normal-hearing peers in the clustering and time course of word…
