Open Access Presidential Scholars Thesis
Velopharyngeal insufficiency; Speech disorders in children;
Analysis of the durational data of the hypernasal subjects revealed that these subjects produced significantly longer primary stressed syllables. This result may indicate a type of laryngeal compenstation on the part of these speakers. Since they did not rely on an increase in frequency when producing stress, they may have used an increase in duration to compensate. Therefore, a deviance in the upper vocal tract may be causing differences in the physiology of the lower vocal tract for this population.
Further research is needed in this area to substantiate the present study. More information should be obtained in the area of stress production and suprasegmentals in both normal children and children with velopharyngeal incompetence. With the advent further research, coupled with this investigation, speech-language pathologists may be better able to serve this population and aid them in acquiring more normal speech patterns.
