Changes in the fundamental frequency and intensity were measured for utterances of the five Japanese vowels and a sentence of greeting and a song by 42 deaf and hard of hearing children (aged 6 to 11), and their characteristics were studied in comparison with those of 9 normal children (aged 7 to 12). Characteristic differences between defective speech and normal speech were found in the relationships between the following : variation among fundamental frequency of each of the five vowels for each subject and his hearing loss, average fundamental frequency in greeting for each subject and his age, the total duration and the duration of voiced portions in greeting, and accuracies of rhythm and note in singing. Correlation between these physical characteristics. physiological characteristics and the evaluations of the speech of deaf and hard 00 hearing children was examined by means of principal component analysis.
