Objective: To analyze the effects of prolonged use of the voice of men who do not use their voices professionally. Method: Descriptive study, approved by the ethics and research committee (CAEE:79911817.2.0000.5546) The study included five nonprofessional voice men, aged between 25 and 55 years, submitted to a continuous speech test for 90 minutes in intensity and usual frequency. The following procedures were performed: extraction of acoustic measurements, spectrographic tracing, perceptual-auditory judgment, Self-Perception of Vocal Fatigue (VAF) protocol before and after prolonged use of the voice and the Screening Index for Voice Disorder. Results: The self-reported symptoms of vocal fatigue after prolonged use of the voice were low pitch, need for laryngeal cleaning, laryngopharyngeal dryness and burning sensation when speaking, prolonged use of the voice caused changes in the vocal quality of some of the participants. Acoustic measures of fundamental frequency (F0), high frequency (Fhi), low frequency (Flo), percentage jitter and harmonic-to-noise ratio (NHR) increased after prolonged use of the voice, and shimmer decreased after ninety minutes of use. continuous use of voice. In the analysis of the spectrographic tracing, the presence of irregularity in the tracing was found, presence of harmonic with little brightness, increase in energy between 1000 and 3000 Hz and presence of irregular harmonics. Conclusion: after 90 minutes of prolonged use of the voice, there was an increase in the perception of vocal symptoms, and these symptoms may be related to the lack of laryngeal hydration, as well as changes in acoustic measures, vocal quality and spectrographic tracing.
