title: A perceptual study of the voicing feature of stop consonants after type II and III laser cordectomies.
abstract: This article deals with the intelligibility of stop consonants in onset position (initial and intervocalic) as pronounced by 10 French speakers treated by a type II or III cordectomy. These surgeries cause a less efficient glottal closure and a vibratory asymmetry. The voicing contrast in consonants may be altered. The patients' vocal samples were made up of non-words of the CVCVCVC type, where C = /p, t, k, b, d, g/ and V = /a, i, u/(n = 360), and were given to 22 French listeners for evaluation. Two identification tests were created and the listeners were asked to choose the consonants they thought they recognized (n = 7920). The results were presented in the form of a confusion matrix highlighting possible confusions of voicing and/or places of articulation. We showed high identification rates of consonants, which revealed an intact voicing contrast in this dysphonic population.
