[The study on the standardization of adults voice acoustic parameters by objective analysis].

ABSTRACT

OBJECTIVE: To explore the characteristic of normal voice in different age-bracket of Chinese adults and to formulate the normal reference value suited to our country at voice assessment. METHOD: We divided the adults into the youth, the middle-aged and the old groups, and analyzed normal voice samples with Dr. Speech software and computer multimedia technique and compared the following 5 parameters (Jitter, Shimmer, NNE, Fo and SDFo) of different groups divided according to one's age, sex and vowel. RESULT: There is difference among the group of age, sex and vowel in most acoustic parameters in the adults. CONCLUSION: To initiate taking multi-vowels samples and using different normal reference value and multi-parameters analysis according to the difference of age-bracket, sex and vowel in the adults.
