PURPOSE: to characterize, by means of phonetography, the profile of voice extension in individuals with post changes, dentofacial balanced voice. METHOD: fifteen male individuals participated in this study, in vocal postmutation, aged between 14 and 35 years old. They answered a specific self-response questionnaire, and they were also submitted to an anthropometric assessment of the face, dento-occlusal evaluation, phonetography examination and to an analysis of the usual fundamental frequency of the voice. RESULTS: minimum Fundamental Frequency: =89Hz±3Hz or =29st±14st, Maximum Fundamental Frequency: X=665Hz±179Hz or X=63st±5, Voice Extension: X=34st±6st, Minimum Intensity: X=66dB±3dB, Maximum Intensity: X=114dB±5dB, Maximum Dynamic Extension: X=42dB±4dB, Phonetogram Area: X=936,4dB.st±258,8dB.st or X=42,1cm²±11,6cm², Usual Fundamental Frequency of the "a" vowel: X=111,26Hz±15,24Hz. CONCLUSION: although national and international studies presented in this work do not consider the dentofacial condition of the subjects, the results were very similar.
