The objective of this study was to investigate the perceptual relevance of acoustic differences in vowels produced by 6 children between the ages of 9-13 years old with unilateral cochlear implants. Formant frequencies were estimated for 12 repetitions of vowels /hid/, /hed/, /haed/, /hud/, /hUd/, and /hAd/ produced by the children. The estimated…

With modern improvements to hearing aids and cochlear implant (CI) technology, and consequently improved access to speech, there has been greater emphasis on listening-based therapies for children with hearing loss, such as auditory-verbal therapy (AVT). Speech and language, speech perception in noise, and reading were evaluated before and after…

This study compared how one typical 8-year old and two 8-year olds with profound deafness conveyed contrastive stress in their speech in simple declarative sentences. For the students with deafness, intensity measurements showed little variation across sentences and no intensity peaks corresponding to the syllables that should be contrastive.…

The vocalizations and speech production of 20 infants with hearing impairments were examined at three age levels: between 5-13 months, 2-5 years, and 5-10 years. Degree of hearing loss had a significant and moderately strong relationship with speech outcome at the second and third age levels. (Contains extensive references.) (Author/CR)
