Ten children (mean age = 6 years, 7 months) who misarticulated /r/ participated in a task designed to survey inconsistent misarticulatory behavior, repeating 51 sentences during each of three trials. (Author/IM)

Pressure buildup patterns preceding the onset of phonation were studied in 573 fluent utterances of 10 stutterers and in 552 utterances of 7 controls. Stutterers evidenced deviant patterns of subglottal pressure buildup and abrupt voice onsets more often than did controls; occurrence of jitter and shimmer did not differ significantly. (Author/JDD)

The relationships between speech parameters and speech intelligibility of 40 severely to profoundly hearing-impaired adults were studied. Regression analysis revealed that speech intelligibility was predicted by a cognate-pair voice-onset-time difference measure and a measure of the stability of the volume-velocity rise time.

Examines the potential usefulness of various procedures employed to measure the adaptation in frequency rate of fluency failure, adaptation in temporal rate of speech, and automated analysis of on-off speech patterns in differentiating stuttering from cluttering. (SCC)

Fifty-four audiologists were asked to predict future speech intelligibility in hearing-impaired children based on four pure-tone audiograms. Predictions varied significantly with degree of loss and status of high-frequency hearing. Audiologists with greater clinical experience had less faith in audiograms as predictors of speech skills than had…

Measurement of voice onset time productions associated with three bilabial, three alveolar, and two velar stops in 3- to 7-year-olds and adults indicated that, by five years of age, children have acquired all voicing contrasts; however, not all sounds are produced in an adult-like manner.

Research is reported that showed phonetic and phonological training to be given peripheral attention or neglected in second language instruction in one geographic area. It is suggested this neglect stems from (1) low teacher and student expectation of success in attaining a native-like accent, and (2) assumptions that a non-native-like accent will…

A study of four children with deafness who had cochlear implants investigated the use of negative intraoral air pressure in articulation, from both the physiological and phonological perspectives. The study showed that the children used speech-production strategies that were different from hearing children and that deviant speech behaviors should…

A study of 16 children (ages 4 and 7 years) and 8 young adults used an "Optotrak" system to study patterning and stability of speech movements in developing speech motor systems. Results indicate that nonlinear and nonuniform changes occur in components of the speech motor system during development. (Author/CR)

Seventeen children (ages 6-11) with developmental apraxia of speech were administered tests of identification and discrimination of resynthesized and synthesized monosyllabic words differing in place of articulation of the initial voiced stop consonants and intensity of the third formant. Results indicated no phonetic processing deficit in…

Presented are rating scales designed to assess severity in communication problems of elementary and secondary students and described is a training program connected with the scales. The scales are explained to provide a 5-point rating for language, voice, articulation, and fluency. The training program section includes sample historical…

Research reports on the nature of speech, instrumentation for the investigation of speech, and practical applications of research are included in this status report for the April 1-June 30, 1980, period. The reports deal with the following topics: (1) the perceptual equivalent of two acoustic cues for a speech contrast is specific to phonetic…
