Research on the Influence of the Hearing impaired in Acquisition of the Intonation Information on Mother Tongue

关于口语的语调信息应该以声音的基本要素为特征，如响度、音调和长度。这些信息不是直观的书面形式。本研究由两部分组成。第一部分考虑了口音或语调的听力辨别能力与听力水平的相关性。很明显，70岁或70岁以下的候选人孩子在口音上被故意歧视。此外，在语调上被故意歧视的候选儿童的dBHL约为100或更少。对于听力障碍儿童，语调比重音更容易辨别，句尾发音时间被用作参数。并分析了陈述句和疑问句的辩解策略。通过延长疑问句句尾的发声时间，表现为陈述句和疑问句的说与分。第二部分，以听力正常儿童为对象，对听障儿童方言的操作频率进行了测量。结果表明：1)与听力正常儿童相比，听障儿童方言的使用率和理解率都较低；2)即使有听力障碍的儿童，也有高频使用该方言的儿童；3)但是，听力水平或听力辨别能力与语言的使用率和对方言的理解率之间没有显著的相关性；4)推测语言环境的影响除了听力水平外，还有很大的影响。

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 accentThe 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 low2)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 dialect4)It was guessed that the influence of language environment was large other than hearing level.
