摘要

BACKGROUND; Most professional vocalists undergo vocal and respiratoty training during their careers. The current study investigated their voice duality, especially acous-tic signal stability, by utilizing quantitative indices often used to assess the condition and function of patients’ vocal cords and to follow up the effects of ovice therapy. The aim was to evaluate the effects of vocal training, and to see how the voice quality was influ-enced by the duration of vocal training.
METHOD;Two groups of female students underwent sustained vowel, reading, and conversation tests. One grouphad undergone vocal training(T, N=76)and the other had not(UT, N=33). The mean ages of the two groups were not significantly different(T=17.86years old; UT=17.57 years old; t(100.784)=217,p＞.05 Voice data were recorded and acoustic parameters analyzed, including pitch perturbation(jitter),amplitude perture-bation(shimmer), harmonic to noise ratio(HNR), glottal noise (NNE),fundamentalfrequency(F0),maximum phonation time (MPT), and the s/z ration. Tow tailed indepen-dent t-tests, paired t-tests, and a Pearson correlation coefficient were used to identify significant differences.
BESULTS;the results indicated that the aciusic parameters of the Tgroup were bettet
Than those of the UTgroup with the exception of the s/z ration and HNR. When the vocal training duration was factored in, we found that jitter,HNR, and NNE were negatively correlated with training duration MPT and the F0 of sustained vowels and conversation were positively correlated with training duration. The results demonstrated that voice quality was positiyely correlated with vocal training duration.
CONCLUSION; The results results suggest that vocal training and its duration improved voice quality. Yocal training apparently increased the ability vocalists to control musclrs and respiratorory airstreams, as shown by their performance with reated parameters. Voc al training should therefore prove useful in improving a patient’s voice stability, and quanti-tative acoustic parameters can be used to evaluate and mon itor a patient’s voice stability.
