Abstract
Three hearing‐impaired children were recorded as they attempted to produce monophthongal vowels of American English. Children were matched for age, hearing, and speech and language ability, yet differed in prosthetic devices (a cochlear implant, a tactile aid, or a conventional hearing aid). Children produced vowels with their respective prosthetic aid on and off during four recording sessions over a period of 15 months. Four repetitions of each vowel, in each aid condition, at each recording date were digitized at 20 kHz with 16‐bit precision, analyzed using ILS, and formant tracks obtained_ Geometric means of F1 and F2 were used to represent each utterance in Koenig space. Mean Euclidean distance from the Peterson and Barney equivalent vowel for children [J. Acoust. Soc. Am. 24, 1562–1567 (1952)] was computed, along with the standard deviation, for each vowel set. It was predicted that, if a child's productions improved, either longitudinally or as a function of prosthetic device feedback, these distanc...
