As factors affecting the voice problems of hearing-impaired children, the level of hearing loss, educational setting, training methods and amplification have been considered. The present experiment was undertaken to explore the relationship between the voice problems of the hearing-impaired and their preschool educational settings. Sixty children with severe hearing impairments (80-120 dB) who attended part-time special classes for the hearing-impaired in Tokyo were selected for the observation. Half of them had received preschool education at schools for the deaf, while the remainder had been trained at clinics, attending regular kindergartens. Speech samples used for the present study were continuous monologues recorded on magnetic tape and analyzed in terms of pitch (the average value of fundamental frequency), variation of pitch and rate of utterances using a phonolaryngograph. The results obtained demonstrated that the preschool educational setting affects the severity of voice problems, that is, the speech intelligibility of hearing-impaired children who attended regular kindergartens was better than that of those who were sent to special schools for the deaf.
