| Research Abstract |
We found following result for the children who educated by the total communication mode from infancy and have profound loss. 1, Expansion of semantic network for their acquired words is not sufficient even if they use manual communication system. 2, Clearness of speech (intonation, quality of voice, use of dialect, and emphasis) in children using cochlear implant was improved significantly than in children using hearing aid. We try to learn acoustic cue through cochlear implant during one year and control use of cue sign to a child using cued speech who can't improve speech production after initial cochlear implant usage. His speech is so clear as development of auditory feedback. The clearness of speech is not effect by communication mode if we try to use residual hearing intently even if use the manual mode. 3, Hearing ability in threshold, recognition of environmental sounds and identification of word etc, was improved in spite of communication mode if we try to use residual hearing intently. But, speech production and auditory skill was poor if we try to use residual hearing intently. Therefore, we conclude effect of communication mode to auditory skill development as follows; 1, From the point of speech production and audition, communication mode (especially manual mode) compete auditory skill development if we try to use hearing intently 2, Both ability for visual and auditory is improved each together if we try to use hearing intently.
