The present study was designed to investigate the perceptual and spectrographic features of vocal effort in the speech of severely to profoundly hearing-impaired children and their normal hearing agemates. Recorded vowel and speech samples were obtained from ten normal hearing children, ten severely to profoundly hearing-impaired children attending Oral/Aural educational programs, and eight severely to profoundly hearing-impaired children attending Total Communication programs. The degree of perceived vocal effort for vowels and speech was evaluated, using a nine point equal-appearing-interval scale. In order to obtain a physical measurement for vocal effort, a digital wave analyzer was used to produce vowel spectra, and the amount of in-harmonic (noise) components in each spectrum was indexed as spectral noise level.
