Abstract

<p>　　We investigated the gender categorization ability and the cues used to judge a speaker's gender by children with cochlear implants (CIs) and children with normal hearing (NH). Ten children with CIs and 34 children with NH were administered a gender categorization task, in which the fundamental frequency and formant frequency of a female voice were manipulated as the clues for gender discrimination.</p><p>　　The results showed that the children with NH could correctly categorize the gender of the unambiguous typical voice, but the more the test voice was manipulated ambiguously, the less accurate the gender recognition performance of these children became. Children with CIs could partially categorize the gender of the unambiguous typical voice, however, they could not easily recognize the gender from ambiguously manipulated voices, and their performance was significantly worse than that of the children with NH.</p><p>　　The findings indicate that the children with NH relied on both F0 and formant frequency cues to discriminate the gender from the voice, while those with CIs mainly relied on F0 cues, with limited use of formant frequency cues.</p><p>　　 These findings suggest that we must understand these audiological characteristics of children with CIs in order to provide appropriate support for them in educational settings.</p>
