conclusions the findings of this study indicate that the frequency of disfluencies was increased in difficult syllable structures in comparison to simple syllable structures. according to the results, it seems that certain linguistic features, such as syllable structure can affect speech-motor output in people who stutter through affecting phonological encoding. background stuttering is one of ...

PURPOSE The goals of the present study were to investigate whether (1) the speech disfluencies of preschool-age children are normally distributed; (2) preschool-age children who do (CWS) and do not stutter (CWNS) differ in terms of non-stuttered disfluencies; (3) age, gender, and speech-language ability affect the number and type of disfluencies children produce; and (4) parents' expressed conc...

A general ageing of the organism, including hormonal, psychological, and cognitive changes, affects the person’s speech production, too. The slowdown of mental operations and of the speech organs may affect the fluency of speech, but relatively few papers are specifically devoted to disfluencies in old people’s speech, and the various authors disagree concerning frequency data. In the present p...

In early lexical development, children must learn to map spoken words onto their respective referents. Since multiple objects are typically present when any word is used, a child is charged with the difficult task of inferring the speaker’s intended referent. Previous research has uncovered various cues children may use in this task, including contextual and social cues. We investigate a previo...

The age-dependent changes of one’s speech production from childhood up to old age are relatively well known. However, there has been less research conducted concerning the possible alterations of the disfluency phenomena in speakers’ spontaneous speech determined by age. Our hypothesis is that permanent changes are going on in the operation of speech production processes from early childhood up...

Williams syndrome (WS) is a neurodevelopmental genetic disorder, often referred as being characterized by dissociation between verbal and non-verbal abilities, although the number of studies disputing this proposal is emerging. Indeed, although they have been traditionally reported as displaying increased speech fluency, this topic has not been fully addressed in research. In previous studies c...

Purpose The aim of this study was to investigate how different types background noise that differ in their level linguistic content affect speech acoustics, fluency, and language production for young adult speakers when performing a monologue discourse task. Method Forty adults monologued by responding open-ended questions silent baseline five conditions (debate, movie dialogue, contemporary mu...

Frequency shifted feedback (FSF) induces fluency when presented to speakers who stutter. This study examined whether FSF was more effective at removing disfluencies on easy or on difficult stretches of speech (where difficulty was defined with respect to utterance and word length). There were more disfluencies on the difficult stretches than on the easy stretches. There were significantly fewer...

Stuttering also known as stammering is fluency disorder in which it affects the flow of speech, an involuntary repetitions, prolongation of sounds, syllables, phrase or words, and involuntary silent pause or blocks in communication. This involuntary speech disorder involves frequent and significant problems with the normal fluency and flow of speech. The number of disfluencies present in a spee...

OBJECTIVE The purpose of the present study was to analyze the frequency and type of speech disfluencies in a relatively large group of individuals with Tourette's syndrome (TS) and to compare their results with similar speech data from a control group of unselected individuals. METHOD Self-report data, as well as conversation and reading samples, were obtained from 69 children diagnosed with ...
