Background: Although speech and voice disorders are common in Parkinson's disease (PD), there is insufficient evidence to support the effectiveness of behavioural speech therapies in these patients. Aims: This study aimed to examine the effects of a new tele-rehabilitation program, a combining of conventional speech therapy and singing…

Purpose: Almost 90% of people with Parkinson's disease (PD) develop voice and speech disorders during the course of the disease. Ventilatory dysfunction is one of the main causes. We aimed to evaluate relationships between respiratory impairments and speech/voice changes in PD. Method: At Day 15 from admission, in consecutive clinically stable PD…

Purpose: The purpose of this study is to familiarize speech-language-pathologists with the current state of the science regarding medialization laryngoplasty in the treatment of voice disorders, with emphasis on current evidence-based practice, voice outcomes, and future directions for research. Method: A literature review was performed in PubMed…

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…

Background: Articulatory excursion and vocal intensity are reduced in many children with dysarthria due to cerebral palsy (CP), contributing to the children's intelligibility deficits and negatively affecting their social participation. However, the effects of speech-treatment strategies for improving intelligibility in this population are…

Background: Speech disorders are a feature of Parkinson's disease, typically worsening as the disease progresses. The Lee Silverman Voice Treatment (LSVT) was developed to address these difficulties. It targets vocal loudness as a means of increasing vocal effort and improving coordination across the subsystems of speech. Aims: Currently LSVT is…

Glottal stops are conveyed by an abrupt constriction at the level of the glottis. Tracheoesophageal (TE) speakers are known to have poor control over the new voice source (neoglottis), and this might influence the production of "glottal" stops. This study investigated how TE speakers realized "glottal" stops in abutting words…

Intraoral air pressure was recorded during the production of consonant cognate pairs by 8 esophageal speakers (mean age 67 years) under 2 experimental conditions: after the insufflation of air and without air insufflation. Results revealed that peak intraoral air pressure magnitudes were significantly greater following the insufflation of air than…

This study examined the interaction of ambient frequency and feature complexity in the diphthong errors produced by 13 Cantonese-speaking children with phonological disorders. Perceptual analysis of 611 diphthongs identified those most frequently and least frequently in error. Suggested treatment guidelines include consideration of three factors:…

This tutorial in nonlinear phonology introduces the basic concepts and assumptions of this new theoretical approach and then demonstrates clinical applications of the theory for assessment and intervention. Data from a child with a severe phonological disorder are used to illustrate aspects of nonlinear theory. (Author/DB)

Various speech and voice disorders affect 70% to 85% of individuals with Parkinson's disease (PD). Speech treatment is generally conducted on an individual basis, with family member involvement. Clinical experience indicates that many patients do not practice treatments at home or apply the learned techniques in everyday situations. An…

This article describes an approach to the treatment of young children whose speech problems are classified in the category of "persistent sound system disorder." The approach fosters development of stimulability skills through broadening of the phonetic inventory early in the treatment process. A case study illustrates treatment…

Treatment of articulation/phonological disorders with electropalatography (in which speech learners wear a custom-made appliance called a pseudopalate in order to view their tongue-to-palate contacts on a computer monitor) is described. Studies of the treatment's effectiveness with children having articulation or phonological disorders are…

A cooperative service delivery model was successfully developed between a university clinic and a public school system to evaluate and treat a child (age seven) with phoneme-specific nasal emission, enabling the child to establish correct production in the clinic setting and transfer production in a school treatment program. (Author/DB)

Verifies observations made of the American Indian population, who appear to demonstrate a high incidence of chronic hoarseness. Examines hoarseness in the general population, American Indian communication styles, causes of Indian voice disorders, study methods, and study results. Speculates that one possibility for the hoarseness is the…
