The purpose was to determine the clinical value of a multiparametric objective voice evaluation protocol including acoustic and aerodynamic parameters measured mainly on a sustained /a/. This was done by comparison with perceptual analysis of continuous speech by a jury composed of 6 experienced listeners. Voice samples (continuous speech) from 63 male(More)
Choice of voice sample material can influence perceptual judgments by a jury. The twofold purpose of this study was first to validate the pertinence of a sustained vowel for perceptual voice analysis in French speakers and second to test the hypothesis that use of only the stabilized portion of the vowel would lead to underestimation of dysphonia. Voice(More)
Various rating scales have been used for perceptual voice analysis including ordinal (ORD) scales and visual analog (VA) scales. The purpose of this study was to determine the most suitable scale for studies using perceptual voice analysis as a gold standard for validation of objective analysis protocols. The study was carried out on 74 female voice samples(More)
This paper describes two comparative studies of voice quality assessment based on complementary approaches. The first study was undertaken on 449 speakers (including 391 dys-phonic patients) whose voice quality was evaluated in parallel by a perceptual judgment and objective measurements on acoustic and aerodynamic data. Results showed that a non-linear(More)
The purpose of this study was to develop and test a training protocol for the perceptual evaluation of dysphonia. A group of 38 inexperienced listeners participated in a three-phase experiment: a pretest to evaluate their initial performance on categorization of dysphonic voices, a training phase, and a posttest to detect training-related changes in(More)
In our society, based on communication, dysphonia becomes a handicap that could be responsible of work discrimination. Actually, several commercial services are provided by phone only, and voice quality is mandatory for the employees. This work aim was to determine the social picture relayed by dysphonia. Our hypothesis was that dysphonia sounds pejorative(More)
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(More)
The aim of this study was to define a new temporal measurement of voice onset. If in fact it has been established that voice onset contains perceptive information which the listening panel uses to evaluate dysphonia, up till now there has been no objective measurement of this. In order to be able to use instrumental measurement of voice onset, it was first(More)
