[The receiving process of speech sounds by a hard-of-hearing child with Down's syndrome (author's transl)].
In four experiments, difficulties in receiving speech sounds and the effect of hearing loss on discrimination between them, were analyzed for a hard-of-hearing boy with Down's Syndrome (11-yr-old). Results showed that (a) when the task consisted of pairs of speech sounds containing the different vowel-combinations, for example [hana]-(article, see text), he could learn to discriminate between them easily through the training to match them with the corresponding picture cards, but (b) when the task consisted of pairs of speech sounds containing the same vowel-combination, such as (article, see text), he could not discriminate between them, and (c) although it was difficult for him to acquire the acoustic cues to discriminate among consonants, he could learn to discriminate between some of the difficult pairs by repeated practice.
