The purpose of this study was to explore the speechreading tendency in children with severe hearing loss.
The subjects were sampled by 50 children with severe hearing loss in day school for the deaf, and 50 normal children in primary public school.
The test materials in Korean language for speechreading test were selected in this study according to the essential and basic criterial which were emphasized by Barley. The test items consisted of 84 monosyllables in two positions (initial and middle).
The speechreading test was performed in the sound proof room of the laboratory of audiology and speech pathology, department of special education, Korean Social Work College employing the canovision 94-56 type. The period of the test was from July 14, 1978 through July 20, 1978.
Main conclusions obtained from the results of speechreading test can be compiled as follows: 1. Total mean scores of 84 monosyllables are shown by 13.01% in the hearing-impaired and 17.87% in the normal hearing.
2. The [a] group and [o] group were generally higher than the other groups in the mean scores of the vowel test. There are shown by 0.1% significant difference statistically between the normal hearing group and the hearing-impaired group in [a] group, [o] group, [i] group.
3. As for consonants by articulatory operations, there are shown by 0.1% significant difference statistically between the normal hearing group and the hearing-impaired group in the mean scores of plosive, nasal, fricative and affricative group.
4. As for consonants by articulatory organs, there are shown by 0.1% significant difference statistically between the hearing-impaired group and the normal hearing group inp the mean scores of palatal and glottal group.
Mean scores-of the hearing-impaired group were high in bilabial group, velar group andalveolar group but low in palatal and glottal group.
5. As for consonants by existence with vibration of the vocal cords, significant difference statisticaay between the hearing impaired group and the normal hearing group are shown by 1% in voice group, and 0. -1,16 in voiceless group.
&. To develop and improve materials for the speechreading test of the hearing-impaired, the more detailed analysis of each sound is demended.
