Objective: To investigate the auditory perception of dysphonic women regarding the parameters of roughness and breathiness in vocal quality. Methods: 22 dysphonic women attended at the Integrated Laboratory of Voice Studies (LIEV) of the Speech Therapy Department of the Federal University of Paraíba - UFPB participated in this research. The volunteers filled out the vocal screening form, the ESV vocal self-assessment protocol (vocal symptom scale), recorded the voice during the emission of the vowel / Ɛ /, whose degree of deviation was examined through the auditory-perceptual and acoustic evaluation; all participants performed audiometry. For the perception tests, five tasks were performed. The first experiment consisted of presenting 32 stimuli in isolation, at random, with eight healthy voices and 24 with different degrees of deviation, so that each participant could classify it as normal or altered. In the second experiment, the participants heard only breathy voices and healthy voices, and must discriminate the presence or absence of breathiness. The third experiment was similar to the second, but with rough voices. In the fourth experiment, 12 breathy voices were presented, in 6 pairs with adjacent degrees of deviation, presented three times each, randomized by PRAAT, so that the participants could discriminate which of the two voices (A or B) had a higher degree of breathiness. The fifth experiment was similar to the fourth, but with rough voices. Results: There was a difference between the ideal correctness and the number of correct answers by dysphonic women in relation to the presence judgment (42.80%), absence (57.38%) of vocal deviation, presence of slight degree of roughness (31.81 %), moderate (65.90%), intense (73.86%) and presence of mild breathiness (46.59%), moderate (55.68%), intense (93.18%). There was a difference between the ideal hit and the number of hits by dysphonic women in relation to the judgment of the presence of normality (57.38%) and breathiness (63.13%). There was a difference between the ideal correct answer and the number of correct answers by dysphonic women regarding the degree of mild breathiness (55.05%), moderate (49.49%) and intense (84.84%). There was a difference between the ideal hit and the number of hits by dysphonic women in relation to the judgment of the presence of normality (87.08%) and roughness (65.31%). There was a difference between the ideal correctness and the number of correct answers by dysphonic women regarding the degree of light roughness (27.07%), moderate (68.06%) and intense (99.04%). Conclusions: It was possible to verify that there are differences regarding the auditory perception of dysphonic women in the identification of healthy and deviated voices. Most deviated voices were identified as normal. The correlation between the degree of vocal deviation and the auditory perception of dysphonic women was demonstrated. The voices with the highest degree of vocal deviation obtained a higher number of correct answers. It was confirmed that there are differences regarding the auditory perception of dysphonic women in the identification of healthy and breathy voices and between the different degrees of breathiness. Dysphonic women demonstrate less ability to perceive breathiness in mild and moderate degrees. There are differences regarding the auditory perception of dysphonic women in the identification of healthy and rough voices and between the different degrees of roughness. Dysphonic women have less ability to perceive roughness in mild degree. The presence of vocal deviation in rough voices is more noticeable than in breathy voices. Dysphonic women experienced difficulties in discriminating adjacent degrees of roughness.
