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…

Background: Multiple sclerosis (MS) is an autoimmune disease that attacks the central nervous system and has several subtypes. The disease pathophysiology includes damage to the myelin in the brain and spinal cord, manifesting in a wide range of neurological symptoms and impacting patients' physical, psychological, social, and communication…

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…

This study examined the relationship between complexity, accuracy and fluency (CAF), using longitudinal data. Conducted from the perspective of complex dynamic systems theory (CDST), this research adopted four CAF general measures to track the development of five Chinese undergraduates' English speech over a 15-week period. LOWESS graphs supported…

This study investigates the speech rate of Cypriot Greek-speaking children with developmental language disorder (DLD) as well as the effect of age and gender. The participants were 16 children with DLD ages 4 years 11 months to 8 years 1 month and 22 children with typical language development (TLD) ages 4 years 5 months to 8 years 7 months. Both…

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…

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: 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…

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…
