Purpose: This study examines how ultrasound biofeedback and intensive treatment distribution affect speech sound generalization during an evidence-based treatment, Speech Motor Chaining, for children with persisting speech errors associated with childhood apraxia of speech (CAS). Method: In a 2 × 2 factorial randomized controlled trial, children…

Background: Individuals with developmental dysarthria typically demonstrate reduced functioning of one or more of the speech subsystems, which negatively impacts speech intelligibility and communication within social contexts. A few treatment approaches are available for improving speech production and intelligibility among individuals with…

Purpose: This study evaluated whether outcomes from treatment, which includes ultrasound visual feedback (UVF), would be more or less effective when combined with auditory perception training for children with residual /[voiced alveolar approximant]/ errors. Method: Children ages 8-16 years with /[voiced alveolar approximant]/ distortions…

Purpose: This study aimed to identify predictors of response to treatment for residual speech sound disorder (RSSD) affecting English rhotics. Progress was tracked during an initial phase of traditional motor-based treatment and a longer phase of treatment incorporating ultrasound biofeedback. Based on previous literature, we focused on baseline…

Purpose: This study documented the efficacy of visual-acoustic biofeedback intervention for residual rhotic errors, relative to a comparison condition involving traditional articulatory treatment. All participants received both treatments in a single-subject experimental design featuring alternating treatments with blocked randomization of…

An adolescent with a persistent frontal lisp participated in a two-part 11-session intervention case study. The first phase used ultrasound imagery and acoustic, phonetic and voice education to provide information about articulatory setting (AS) and general awareness of the speech production process. The second phase used traditional articulation…

Children with cerebral palsy often have speech, language and communication difficulties that affect their access to social and educational activities. Speech and language therapy to improve the intelligibility of the speech of children with cerebral palsy has long been advocated, but there is a dearth of research investigating therapy…

Twenty-six children and adolescents who were unable to produce /r/ correctly listened to a tape of 200 words containing /r/ spoken, either correctly or incorrectly, by either the subjects themselves or another speaker. Subjects judged both the correctness of the /r/ and the speaker's identity. Results support a relationship between speech…

A TWO-PHASE PROJECT CONCERNED WITH THE EFFECTIVENESS OF SPEECH THERAPY WITH EDUCABLE MENTALLY RETARDED (EMR) CHILDREN IN A PUBLIC SCHOOL SETTING HAD TWO OBJECTIVES--TO ASSEMBLE A REASONABLY COMPLETE PICTURE OF ARTICULATION OF EDUCABLE MENTALLY RETARDED CHILDREN AND TO DETERMINE THE VALUE OF SPEECH THERAPY TO EMR CHILDREN WITH ARTICULATION…

Purpose: This study investigated formant frequencies for their role as acoustic and perceptual correlates to the place of articulation of Cantonese final stops produced by profoundly hearing impaired speakers. Method: Speakers were 10 Cantonese adolescents (mean age = 13;5 [years;months]) who were profoundly hearing impaired (HI). Control speakers…

The present paper comprises an overview of techniques using ultrasound in speech (re)habilitation. Ultrasound treatment techniques have been developed for English lingual stops, vowels, sibilants, and liquids. These techniques come from a series of small "n" studies with adolescents and adults with severe hearing impairment, residual…

THIS BOOK IS DESIGNED PRIMARILY FOR STUDENTS WHO ARE BEING TRAINED TO WORK WITH SPEECH HANDICAPPED SCHOOL CHILDREN, EITHER AS SPEECH CORRECTIONISTS OR AS CLASSROOM TEACHERS. THE BOOK DEALS WITH FOUR MAJOR QUESTIONS--(1) WHAT KINDS OF SPEECH DISORDERS ARE FOUND AMONG SCHOOL CHILDREN, (2) WHAT ARE THE PHYSICAL, PSYCHOLOGICAL AND SOCIAL CONDITIONS,…
