Criterion-Referred Making For Prephonation Period Voice Assessment And Their Clinic Applications Research

Voice assessment Comprehensively is the basis of voice treatment. With the development of computer technology and voice medicine, more and more objective or subjective voice measurements are applied in voice clinic and researchs, especially objective voice measurement playing a very important role in the diagnosis and treatment for voice disorders.This PH.D dissertation research on the voice function measurement of prephonation period first time, selecting F0,Jitter,OQ,SQ,STF and AQ as research parameters, using a new voice measurement instrument (Phonation) which can analyze the wave on the prephonation period and the stabilization period. The research contents include:the lab research of voice parameters contrast between the prephonation period and the stabilization period; The lab research about voice mesuring material selecting for prephonation period; The lab research about contrasts between normal and pathonogic voice in adult and preeducation-age children; The lab researchs about prephonation period parameters analysis for normal adult and preeducation children voice; The experiments of establishing reference standards of prephonation period parameters and the application of which in the voice clinic.Through a series of experiments about the prephonation period voice parameters, some results have achieved:(1) The voice parameters of the prephonation period are significantly different from the stabilization period; (2) Selecting the best material for the prephonation period assessment;(3)There are obviously differences between male and female at prephonation period voice parameters while no differences in preeducation children at age and gender. (4) Establishing the reference standards of the prephonation period for adults and preeducation children, which provide a new approach for voice clinic. (5) There are differences at the prephonation period voice parameters among different types of voice disorder. (6) Validating the useful of prephonation period voice parameters and the effect of their reference standards through experiments and one case study.This paper proved that the research on prephonation period is very significant for voice disorders diagnosis and the monitor for voice treatment. In subsequent study, we'll add the specimen number in researchs and expend the types of voice diseases, further research the characters of the prephonation period voice parameters on normal and pathonogic voice. On the other hand, we should expend the application of these parameters in voice clinic and research.
