• A preliminary study of the speech discrimination test using highly familiar syllabic words

抄録

Seven Subjects with normal hearing level (NORM) and five with moderate sensorineural deafness (DEAF) were subjected to a speech discrimination test using both 4-mora highly familiar syllabic words and meaningless monosyllabic words in a sound-free field with artificial speech noise (SNR-27dB, -18dB, -9dB).<br>The following results were obtained in relation to the discrimination scores:<br>The NORM group showed a high discrimination score for both 4-mora syllabic words and monosyllabic words when the artificial noise level was efficient (phonemic restoration).<br>A perceptual synthesis for the missing speech sounds was observed in both the NORM and DEAF groups.<br>We concluded that the top-down mechanism for speech recognition in the human brain will affect the discrimination score when the word familiarity is high enough in both NORM and DEAF subjects. However, two cases of DEAF showed a poor discrimination score due to the auditory deprivation.
