Speaking fundamental frequency characteristics of institutionalized adults with Down's syndrome.
Mean speaking fundamental frequency was obtained from 16 institutionalized adults with Down's syndrome (8 males, 8 females) and from 16 nonretarded adults of similar age and sex. Both male and female adults with Down's syndrome exhibited a higher mean speaking fundamental frequency than did the nonretarded adults of the same sex. This finding does not support early reports of a characteristically low-pitched voice among Down's syndrome individuals.
