Listeners' perceptions of nonspeech characteristics of normal and dysarthric children.
The purpose of this investigation was to compare listeners' evaluations of nonspeech characteristics of dysarthric and normal speakers. A total of 16 speakers, eight cerebral-palsied and eight normal children ranging in age from 6 to 11 years, recorded six three-word phrases. The cerebral-palsied speakers were judged to have disorders in at least two of the three areas of articulation, phonation, and resonance, and all were judged to have an articulation disorder as one of the two disordered areas. All normal speakers were found to have normal speech characteristics. A master tape containing the 16 speakers' recordings was presented to 25 listeners, who were asked to rate each of the speakers on a 24-item semantic differential scale that contained polarized adjective pairs concerned with personality and physical-appearance traits. Results of their ratings indicated that for all but two of the 24 adjective pairs, the normal speakers were judged more favorably than the dysarthric speakers, and for all but one of the 24 adjective pairs there were significant differences in judges' ratings between the normal and dysarthric speakers. It appears, therefore, that dysarthric speech adversely affected listeners' perceptions of the dysarthric speakers' personality and physical-appearance characteristics.
