PurposeTo compare and to correlate the performance of women with behavioral dysphonia and without voice disorders in auditory processing tests and in the Voice Tone Reproduction Test (VTRT).MethodsForty women aged from 18 to 44 years participated and were divided in two groups: dysphonic (DG) and non-dysphonic (NDG). The participants underwent interview, hearing, otorhinolaryngology and voice assessments (voice record, VTRT through phonetography), and auditory processing assessment—using the Pitch Pattern Sequence (PPS) test and the Duration Pattern Sequence (DPS) test. The statistical analysis compared both groups, and there was a correlation test (P < 0.05).ResultsThe NDG had a better performance in the PPS test (P = 0.000), in the VTRT test in the first attempt (P = 0.025), and in the total of correct answers (P = 0.017). There was a positive correlation between the PPS and both the first attempt of the VTRT and the total number of attempts. Regarding the DPS, there was a positive correlation for the left ear with the total number of VTRT attempts.ConclusionsDysphonic women presented disorders in temporal auditory processing skills, revealing an important relation between vocal production and impairment of some central auditory functions. There was a positive correlation between the performance in the auditory processing assessment and the performance in voice tone reproduction in both groups. The VTRT may assist speech therapists and voice trainers in verifying difficulties of auditory perception of dysphonic women when the cause is due to behavioral tdysphonia.
