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)
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)

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)
