The speech intelligibility of 36 hearing-impaired children who fitted hearing aids in early childhood was studied in relation to their hearing levels. The materials used to measure intelligibility were 100 Japanese syllables.
The results were summarized as follows; (1) The speech intelligibility of hearing-impaired children depended strongly on hearing levels. The speech intelligibility of jo-ons (contracted sounds) was affected most seriously by hearing levels. (2) The articulation errors of vowels were numerous in cases of 100dB HL or over. (3) In relation to consonants, the articulation errors of nasals, flappeds and plusives were numerous in cases of 100dB HL or over, and those of fricatives were in cases of 80dB HL or over. The articulation errors of affricates were numerous even in cases of 79dB HL or below.
