BACKGROUND: vocal acoustic characteristics of the filter and the male measures of the vocal source. PURPOSE: to accomplish a literature review describing and discussing the aspects that involve the vocal acoustic characteristic in men with normal laryngeal related to measures of the source and the vocal filter. CONCLUSION: the measures related to Jita, ShdB and NRH tend to be bigger in men, when f0, PHR/HNR and ATRI tend to be smaller. Spectrographies tend to show deep formants with darker variation and less regular than in women.
