Children with cochlear implants may have difficulties in recognizing information based on pitch and expression of suprasegmental features. This study is to investigate the relationship between the affective prosodic characteristics in children with cochlear implants and listener’s perception. In order to investigate affective prosody productivity, this study is composed of 3 affective types like happiness, anger, sadness with 5 pseudo sentences. Moreover, this study is to see if there are any differences in recognition(affective type, focus word) of experts group or any relationships between affective prosody characteristic and listener’s perception(affective type, focus word). The subject of the research consisted of normal hearing children group who have the same age and sex to those of cochlear implanted children group. All groups are aged between 7 and 12. The research is analysed with the auditory-perceptual evaluation of experts group and acoustic evaluation using Praat program. The results are as follows: First, according to the result of acoustic analysis, children with cochlear implants and normal hearing children group had meaningful differences statistically in senPitchMedian, senPitchDev, sen_meanPitchAbs_slope, senIntMedian, s_rate, a_rate and in affective types[sadness < happiness < anger]. However, there is no big difference between the main effects on groups and interactive effects on groups and affective types. This result shows that cochlear implants children and normal hearing children have a similar ability of expressing affective prosody. Second, after auditory-perceptually analyzing the perception characteristics of listeners with affective types of group, it was proven that listeners showed higher degree of relation with affective types caused by normal hearing children than those by cochlear implants groups. The results revealed that listeners had more difficulties on perceiving affective types of cochlear implants children than on those of normal hearing children. Statistically, whereas listeners meaningfully perceived affective types produced by cochlear implants children regardless of any purposes[happiness < anger < sadness], they did not meaningfully perceived those produced by normal hearing children. It was shown that listeners perceived that normal hearing children expressed happiness, anger, and sadness by appropriately using affective prosody, but perceived that cochlear implants children felt uncomfortable to express affective prosody. The result of auditory-perceptual analysis on focus perception characteristics of listeners with groups revealed that both two groups showed meaningful differences by choosing the last syllable within a sentence as a focus. This result also showed with auditory-perceptual evaluation that both groups assign the information to the last syllable within a sentence to express affective purposes. Third, the result of the relationship between auditory-perceptual evaulation of affective types and variable of acoustics revealed that cochlear implants children showed high correlation with senNorPitchMax, senPitchRange, senPitchDev, sen_meanPitchAbs_slope. This result also showed that listeners perceived affective types of cochlear implants children by using variables relevant to unnatural pitch parameters. Listeners perceived that cochlear implants children used focus word as wordDur, wordNorPitchMax, wordNorIntMax and normal hearing children used wordDur, wordNorIntMax, wordIntRange, wordIntDev, word_meanIntAbs_slope for choosing focus word. These results imply that listeners make use of more detailed intensity parameters(wordIntRange, wordIntDev, word_meanIntAbs_slope) on perceiving the focus of normal hearing children than on that of cochlear implants children. These results imply that listeners have difficultly perception because of detailed technical deficits despite the fact that cochlear implants’s intention exists to production affective types. When communicating, it is assumed that the lack of application ability of suprasegmental feature which is necessary for faithfully expressing the effectivity of a communication counterpart can be a hindrance. An appropriate instruction is necessary for prosody extension focusing on the affective expression ability of a hearing-impaired child in clinical setting of speech-language rehabilitation. ，韩语毕业论文，韩语论文范文 |
