ABSTRACT
Qualitative descriptions of the consonant inventories of 12 children who have used cochlear implants for at least 5 years are provided, together with description of sound correspondences between children's systems and the ambient language (English). Productions of English words were elicited in a picture-naming task, and a consonant inventory for each child was determined. Results showed that the consonant inventories of children who use cochlear implants are not simply subsets of the inventory of the ambient language, but rather unique sets of segments that may include consonants not in the ambient inventory. Comparison of the inventories of oral communication users and total communication users revealed qualitative differences between the 2 groups, based on the presence or absence of both English and non-English sound segments. Inventories of oral communication users tended to contain more English segments (e.g., alveolar fricatives, velar stops, velar nasals) than did the inventories of total communication users. Conversely, specific non-English segments, such as uvular stops, tended to occur in the inventories of total communication users more than in inventories of oral communication users. Therefore, a complete understanding of the phonological systems of children who use cochlear implants depends on full accounts of their segment inventories. Such understanding may affect decisions regarding habilitation procedures, insofar as successful acquisition of a linguistic system involves not only the inclusion of all ambient sound segments, but also the exclusion of all nonambient ones.
