Two speech perception experiments were conducted with 12 normally hearing adults using a modified speech tracking procedure to determine the effects of controlling connected discourse materials and the effects of specific prompting techniques on tracking rate and subjects' responses. Results showed higher tracking rates for controlled materials.…

This preliminary study examined effects of word visibility and prime association factors on visual spoken word recognition in lipreading, using a related/unrelated prime-target paradigm with 20 hearing adults. In related prime-target pairings, more targets with a high than low prime association were identified. In unrelated prime-target pairings,…

Small-set segmental identification experiments were conducted with three deaf-blind subjects who were highly experienced users of the Tadoma method. Systematic variations in the positioning of the hand on the speaker's face for Tadoma produced systematic effects on percent-correct scores, information transfer, and perception of individual…

Models of stuttering and delayed auditory feedback propose that, in these conditions, the rhythmic structure of fluent speech prespecifing the intervals between vowels of stressed syllables is lacking and that auditory perception of vowels of stressed syllables is predicted incorrectly. A model regarding onset of stuttering in children is also…

This study investigated the multidimensional information underlying accurate speech perception as processed by children with mild to severe hearing impairments. Results suggested that the auditory dimension has a normal strength-of-processing level (thus normally distracting) but that the linguistic dimension has an underdeveloped…

This study used a contrasting word task to evaluate the relationship between specific acoustic features of speech and perceptual judgments of word intelligibility of 16 adults with cerebral palsy-dysarthria. The scaled intelligibility was predicted with 62.6 percent accuracy by acoustic measures related to one consonant contrast and three vowel…

Four groups of 12 young adult deaf subjects evaluated 2 aspects of lipreading training: source of video feedback (self or trainer) and timing of feedback (during or after speech production). Results substantiate the beneficial effects of multisensory feedback by practicing lipreading of one's own speech production. (Author/JDD)

Forty stutterers and forty nonstutterers in Japan were tested for susceptibility to delayed auditory feedback while reading passages under amplified delay conditions. Susceptibility was higher for stutterers than nonstutterers and for nonstuttering men than nonstuttering women. Stutterers appeared to rely on auditory feedback for speech control…

The articulator positions of a man with deafness who had a cochlear implant were measured with an electromagnetic midsagittal articulometer system with and without auditory feedback via his implant. Findings suggest that the cochlear implant was providing important auditory cues that can be used to monitor speech and maintain phonemic contrasts.…

Acoustic and video data tracing the development of intrasyllabic coarticulation suggest that young children (n=30; ages three, five, and eight) and adults (n=10) produce similar patterns of anticipatory coarticulation, and perceptual data indicate that coarticulatory cues in the speech of three year olds are less perceptible than those of the…

Adult stutterers (n=75) and nonstutterers (n=81) rated themselves on communication attitudes involving behavioral, affective, and cognitive components. The findings raise issues regarding stutterers' avoidances, attitude multidimensionality in the perceptions of speaking situations, differences in stutterers and nonstutterers' belief systems, and…
