| Research Abstract |
The intonation information on a spoken language should be characterized with the basic element of sound, such as loudness, pitch, and length. These information is not written visually in written form.
This research consists of two parts. Part I considered correlation with the listening discrimination capability of an accent or intonation, and a hearing level. It became clear to be intentionally discriminated in the candidate child of about 70 or less dBHL in an accent. Moreover, being intentionally discriminated in the candidate child of about 100 or less dBHL in intonation was shown. For the hearing handicapped child, it became clear that intonation can discriminate more easily compared with the accent
The time for utterance of the sentence end was used as a parameter. And strategy of the excuse of a declarative sentence and an interrogative sentence was analyzed. By extending the utterance time of the sentence end of an interrogative sentence showed saying and dividing the declarative sentence and the interrogative sentence.
In part II, the operating frequency of a hearing handicapped children's dialect was usually measured with normal hearing children. And the relation with hearing ability was considered.
As a result, the following things were shown.
1) As compared with normal hearing children, the rate of use of hearing handicapped children's dialect and an understanding are low
2)Even if there was a hearing impaired, there were also those who are using the dialect for high frequency.
3)But, there was no significant correlation between a hearing ability level, or listening discrimination capability, and the rate of use and the rate of an understanding of a dialect
4)It was guessed that the influence of language environment was large other than hearing level.
