Previous work has shown that phonetic difficulty affects older, but not younger, speakers who stutter and that older speakers experience more difficulty on content words than function words. The relationship between stuttering rate and a recently-developed index of phonetic complexity (IPC, Jakielski) was examined in this study separately for function and(More)
INTRODUCTION Stuttering is a speech disorder in which the flow of speech is disrupted by repetitions, prolongation, and blocks of sounds, syllables, or words. No pharmacological treatments are approved for use in stuttering, and the most common form of treatment is speech therapy. This study was designed to assess the safety, tolerability, and effectiveness(More)
UNLABELLED Diadochokinetic (DDK) rates are commonly assessed in children with speech-language disorders, even though the implications of fast or slow DDK rates are not clear. This study explored the possibility that the accuracy and fluency of DDK productions may provide a meaningful supplement to traditional measures of DDK rate. Participants were 15 boys,(More)
UNLABELLED This paper describes several treatment strategies that clinicians can use to address negative affective, behavioral, and cognitive reactions that school-age children who stutter may experience as part of their disorder. Specific strategies include desensitization to stuttering, cognitive restructuring, self-acceptance, purposeful self-disclosure,(More)
In this paper, we present an annotation scheme for disfluencies. Unlike previous schemes, this scheme allows complex disfluen-cies with multiple backtracking points to be annotated, which are common in stuttered speech. The scheme specifies each disfluency in terms of word-level annotations, thus making the scheme useful for building sophisticated language(More)
We present computer tools to help speech-language pathologists (SLP) in counting disfluencies, for both real-time and transcript-based counts. The latter tend to be more precise and show which words are involved in each disfluency. Our approach allows real-time counts to be used as the basis for transcript-based counts. We employ automatic speech(More)
In determining the disfluencies in a speech sample, the emphasis is on the number of disfluencies. Little attention has been paid to the structure of them. Even the approach of Systematic Disfluency Analysis (Campbell, Hill, and Driscoll, 1991), which is probably one of the most detailed analyses, does not precisely indicate which words are involved in the(More)
This study investigated phonological memory in 5- and 6-year old children who stutter. Participants were 11 children who stutter matched on general language abilities, maternal education level, and sex to 11 typically fluent children. Participants completed norm-referenced nonword repetition and digit span tasks, as well as measures of expressive and(More)
Idiopathic stuttering is a fluency disorder characterized by impairments during speech production. Deficits in the motor control circuits of the basal ganglia have been implicated in idiopathic stuttering but it is unclear how these impairments relate to the disorder. Previous work has indicated a possible deficiency in motor inhibition in children who(More)
