Use of Acoustic Cues by Children with Cochlear Implants
Giezen, Marcel R.; Escudero, Paola; Baker, Anne
Journal of Speech, Language, and Hearing Research, v53 n6 p1440-1457 Dec 2010
Purpose: This study examined the use of different acoustic cues in auditory perception of consonant and vowel contrasts by profoundly deaf children with a cochlear implant (CI) in comparison to age-matched children and young adults with normal hearing. Method: A speech sound categorization task in an XAB format was administered to 15 children ages 5-6 with a CI (mean age at implant: 1;8 [years;months]), 20 normal-hearing age-matched children, and 21 normal-hearing adults. Four contrasts were examined: /alpha/-/a/, /I/-/i/, /bu/-/pu/, and /fu/-/su/. Measures included phoneme endpoint identification, individual cue reliance, cue weighting, and classification slope. Results: The children with a CI used the spectral cues in the /fu/-/su/ contrast less effectively than the children with normal hearing, resulting in poorer phoneme endpoint identification and a shallower classification slope. Performance on the other 3 contrasts did not differ significantly. Adults consistently showed steeper classification slopes than the children, but similar cue-weighting patterns were observed in all 3 groups. Conclusions: Despite their different auditory input, children with a CI appear to be able to use many acoustic cues effectively in speech perception. Most importantly, children with a CI and normal-hearing children were observed to use similar cue-weighting patterns.
