The results indicated that the visual feedback was used very effectively by five of the 12 Ss in reducing their excessively nasal voice quality, and somewhat effectively by four others. (Author/DLS)

The speech of four phonologically disordered children (ages four and five) with place and voice errors affecting initial stop consonants was described through phonological and acoustic analyses. The presence of productive phonological knowledge, as inferred from acoustic data, facilitated rapid generalization of correct production of the treated…

This investigation compared five parameters of phonatory function in an examination of the use of acoustic measures in differential diagnosis in 39 subjects in 3 neuropathological groups (Parkinson, Huntington, cerebellar ataxia) and a normal control group. Results indicated higher variability in perturbation in all the neuropathological groups.…

This study evaluated the voiced/voiceless phonation time for /s/ and /z/ for 11 children (ages 5-10) with vocal pathology and 11 normal speaking children. Results showed no difference in /s/ durations between groups, but /z/ durations and s/z ratios were significantly different. Results are discussed in relation to task construction, instructional…

This study investigated two aspects of non-symbolic phonological knowledge (knowledge of the acoustic/perceptual space and of the articulatory/production space) in six preschool-age children with phonological disorders and six typically developing age peers. Results suggest that phonological knowledge is multifaceted, and that seemingly…

Preadolescents with hyperfunctional voice disorders may respond readily to behavioral voice therapy based on education, voice conservation strategies, direct vocal function exercises, family and peer support, and relaxation. Treatment should focus on integration of health respiration, phonation, and vocal tract resonance to achieve improved…

A study investigated voice onset time in voiced stop consonants under varying constraints. Under variation of rate, lexical stress location and location of key words beginning with voiced stops, the three adult stutterers realized voiced stops by voicing before release, whereas controls realized voiced stops by voicing following the release.…

This study presents detailed distributional analyses of voice onset times (VOTs) from seven 5-year-old children and 14 adults. Distributional non-normality was common in both data sets with children showing greater skew. Results suggest that theories of VOT development should not be based solely on means and standard deviations but need to address…

This research note describes the design and testing of a device for unobtrusive, long-term ambulatory monitoring of voice use, named the Portable Vocal Accumulator (PVA). The PVA contains a digital signal processor for analyzing input from a neck-placed miniature accelerometer. During its development, accelerometer recordings were obtained from 99…

The proceedings of the conference/short course on the role of the family as supportive personnel in speech and hearing remediation focus upon the family and its relationship and interaction with the speech, language, or hearing handicapped individual. The purpose of the course was to emphasize the importance of utilizing the family as a manpower…
