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)
This paper addresses voice disorder assessment. It proposes an original back-and-forth methodology involving an automatic classification system as well as knowledge of the human experts (machine learning experts, phoneticians, and pathologists). The goal of this methodology is to bring a better understanding of acoustic phenomena related to dysphonia. The(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)
OBJECTIVES/HYPOTHESIS Voice imitation of a famous personality results in detection and reproduction of some vocal features, including spectral characteristics but also prosody, speech flow, or articulatory patterns. The objective of this study was to describe vocal flexibility in one of the best French impersonators and determine his strategies. STUDY(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)
HYPOTHESIS Objective analysis of the outcome of phonosurgery is needed to allow comparison of different surgical techniques or indications, or both. We tried to demonstrate that measurement of mean oral airflow during the production of a sustained vowel could be used in combination with acoustic measurements such as jitter or shimmer for assessment of voice(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 dysphonic patients) whose voice quality was evaluated in parallel by a perceptual judgment and objective measurements on acoustic and aerodynamic data. Results showed that a nonlinear(More)
INTRODUCTION In this study, we proposed and tested the effectiveness of a training procedure on perceptual evaluation of dysphonia. Participants were naive listeners who learned to judge the severity of vocal disorders. MATERIALS AND METHODS The corpus consisted of 142 female voices ranging from normal to severely dysphonic voices. A total of 38 naive(More)
The objective of the study was to analyze temperament and character in females with vocal nodules (VN) compared to a vocally healthy control population. 61 females were examined over a 17-month period for dysphonia with VN (mean age 46 years, duration of vocal complaints from 2 months to 6 years). 71 control females were recruited in their environment (mean(More)
