Case studies are presented of four children, age four to six, with severe phonological disorders, demonstrating three generations of family members with speech/language problems. An autosomal dominant mode, a multifactorial-polygenic model, and a sex-specific threshold model for expression are discussed. (Author/JDD)

The consonant intelligibility of three esophageal talkers, three tracheoesophageal talkers, and one dual-mode talker was analyzed for overall intelligibility, voicing and manner features, consonant omissions, and speech proficiency. The intelligibility of the tracheoesophageal speech was significantly better than that of the esophageal speech.…

Ten adults with dysarthria of various etiologies, type, and severity were compared to age-matched and gender-matched nondysarthric speakers on 40 short sentences. Results indicated reduced intonation values for the dysarthric group and varying rates as a function of subject group and sentence type. Results suggest that dysarthria is a deficit in…

Vowels produced by four deaf women were analyzed spectrographically to study acoustic correlates of vocal tract deformation. Formant structure evaluated on isovowel lines disclosed consistent neutralization of vowels, which is attributed to observed restricted horizontal movements of the tongue within the oral and pharyngeal cavities.

This study analyzed production of a long vowel sound within Finnish words by normal or dysphonic voices, using the Self-Organizing Map, the artificial neural network algorithm of T. Kohonen which produces two-dimensional representations of speech. The method was found to be both sensitive and specific in the detection of dysphonia. (Author/JDD)

Two voice therapy approaches, vocal hygiene instruction and vocal function exercises, were compared for their functional effects with 58 teachers with voice disorders. Only the exercise group reported a significant reduction in perceived vocal handicap and this group also reported more overall voice improvement and greater ease and clarity in…

The treatment of adolescent clients with hyperfunctional voice disorders is discussed from a developmental perspective. Facilitating techniques, treatment strategies, and materials is suggested. The recommended treatment approach focuses on enhanced awareness of the relationship between voice use and interpersonal skills in addition to behavioral…

This article examines possible causes or intensifications of vocal fatigue in adolescent singers. Factors considered include the adequacy of the singing technique, the strenuousness of the musical task, the physical singing environment, the singer's general condition, and the expectations imposed by the musical leader. Possible management…

The purpose of this study was to explore the biopsychosocial consequences of spasmodic dysphonia (SD) as experienced by people with SD. Qualitative research methods were used to investigate the insider's perspective of living with SD. Six adults with SD participated in face-to-face phenomenological interviews. The results are summarized in a model…

Purpose: The purpose of this study was to examine the attitudes of monolingual English, bilingual Cantonese-English, and bilingual Russian-English speakers toward individuals with voice disorders. METHOD: In a mixed experimental design, a total of 30 older and 29 younger female listeners from the 3 language groups rated the voices of 10 females,…

Discussed are the types, content, physical layout, and use of communication boards, which assist physically handicapped children who cannot communicate orally. (DLS)

Spectrographic measures of voice onset time (VOT) were made for three phonologically disordered children with an emerging voicing contrast. These measures were related to adult listeners' perception of voicing of the initial stop consonant. Results showed that VOT's utility for predicting perceived voicing was not high. (Author/JDD)

Presented is a study of a 20-year-old girl with mild, breathy dysphonia, previously diagnosed as psychogenic. In actuality, her voice change was a sign of early myasthenia gravis. It is pointed out that voice changes can be a first and only sign of early neurologic disease. (Author/KW)
