Purpose: The purpose of this investigation was to examine the impact of instruction order on the speech production response when adopting higher effort speaking styles, specifically loud and clear speech. Method: Speech intensity, lip aperture range, and speech rate data were collected from 24 talkers who repeated the utterance "Buy Bobby a…

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: The purpose of this study was to quantify changes in acoustic distinctiveness in two groups of talkers with Parkinson's disease as they modify across a wide range of speaking rates. Method: People with Parkinson's disease with and without deep brain stimulation and older healthy controls read 24 carrier phrases at different speech rates.…

Aims: Although IDS is typically described as slower than adult-directed speech (ADS), potential impacts of slower speech on language development have not been examined. We explored whether IDS speech rates in 42 mother-infant dyads at four time periods predicted children's language outcomes at two years. Method: We correlated IDS speech rate with…

Purpose: Talkers typically use a slow speaking rate when producing clear speech, a speaking style that has been widely shown to improve intelligibility over conversational speech in difficult communication environments. With training, however, talkers can learn to produce a form of clear speech at normal speaking rates that provides young…

Purpose: Conversational entrainment is the tendency for individuals to modify their behavior to more closely converge with the behavior of their communication partner and is an important aspect of successful interaction. Evidence of entrainment in adults is robust, yet research regarding its development in children is sparse. Here, we investigate…

This study evaluated the effectiveness of simplified habit reversal in reducing filled pauses that occur during public speaking. Filled pauses consist of "uh," "um," or "er"; clicking sounds; and misuse of the word "like." After baseline, participants received habit reversal training that consisted of…

The purpose of this paper is to highlight current U.S. Supreme Court precedents regarding public employee speech on matters of public concern, and how those precedents are being applied by lower federal courts to public school administrators. Surveying the current legal landscape reveals a heightened vulnerability for school administrators…

The main purpose of learning a foreign language is to use it for meaningful and effective communication both inside and outside the classroom. This paper is devoted to identifying the main communication difficulties faced by EFL students at King Khalid University (KKU) and exploring the reasons that lie behind these difficulties. The paper…

Generally, the speaking aspect is not properly debated when discussing the positive and negative effects of television (TV), especially on children. So, to highlight this point, this study was first initialized by asking the question: "What are the effects of TV on speech?" and secondly, to transform the effects that TV has on speech in…

Articulation rate, speaking rate, as well as the duration and location of pauses, were analysed in 10 children with specific language impairment (SLI) and a comparison group of seven younger children producing utterances of similar lengths. Children with SLI were significantly slower in articulation rate, but not speaking rate or pausing time,…

Cooperative conversation has been shown to foster interpersonal postural coordination. The authors investigated whether such coordination is mediated by the influence of articulation on postural sway. In Experiment 1, talkers produced words in synchrony or in alternation, as the authors varied speaking rate and word similarity. Greater shared…

Male and female, black and white political interviewees (M. Albright, B. Clinton, H. Clinton, B. Obama, C. Powell, and C. Rice) of Larry King on CNN TV are used to ascertain whether ethnicity and gender affect the way politicians actually speak. Qualitative comparisons are made of Obama's hesitations and rate with and without a threatening…

Lung volumes and ventilatory patterns used by 10 healthy and 14 asthmatic subjects during conversation, monologue, and counting at two loudness levels were studied. Asthmatics were found to favor respiratory over communications needs. They used a greater percentage of their reduced vital capacity, with slower inspiratory and faster expiratory flow…

Stuttering frequency in 10 adult stutterers (ages 22-48 years) was measured when speaking spontaneously alone, then with an adult male conversationalist, and finally speaking alone again. Percent stuttering increased in the conversational situation compared with the first alone situation and decreased again during the second alone situation.…
