Quantitative Assessment of Nasal Emission During Pronunciation for the Hearing Impaired Children and Normally Hearing Children

Summary/Abstract: In this paper, comparison of the results of quantitative assessment of nasal emission produced during pronunciation of sentences with and without nasal consonants was carried out for the group of hearing impaired children (N=11) and the group of normally hearing children (N=12) by using NasalView system. The relationship between nasal emission, phonation characteristics, speech tempo and pure tone average was also observed. Average nasalance percent during pronunciation of sentences without nasal consonants differed significantly between the two groups of children, as well as the average speech rate, but no general relationship was found between nasalance scores, vocal pitch control, speech tempo and pure tone average. The results suggest that the ability of observed children with hearing loss to control velopharingeal activity is limited, but present, and that it does not depend on the level of phonation control or the control of the speech rate, but rather on individual factors (quality of residual hearing and the successfulness in its use). It is also evident that observed children with hearing loss have certain potential to develop or improve the control of velopharingeal activity in the process of speech and hearing rehabilitation.
