[Influence of voice onset on the perceptual analysis of dysphonia].
The perceptual analysis of voice for 40 dysphonic and normal subjects was studied according to the GRBAS method and with the consensus of three experts. In order to evaluate the effects of voice onset on the evaluation by the jury, we presented two sample materials for each subject: a sustained /alpha/ and the same sustained /alpha/ for which voice onset was suppressed. In a blind test, the two sample materials were presented in the same session in a random way. The jury did not notice the sustained /alpha/ for which voice onset was suppressed.The influence of voice onset on the jury was based on the percentage of identical answers for each material. Our results show that the influence of voice onset is correlated with the dysphonic level. Voice onset would be of major importance for intermediate dysphonia (G1, G2), whereas it seems not to exert any influence in the case of normal voices (G0) or severe dysphonia (G3).
