Abstract:
PURPOSE:
to compare the vocal profile of professional theater actors and of student actors to check if there are differences between their voice use patterns.
METHODS:
the sample consisted of 25 professional actors and 25 student actors. The study was carried out by recording and analyzing the subjects' voices, using the GRBASI scale (auditory-perceptual analysis) and the software Dr. Speech (acoustic analysis). The computerized analysis assessed fundamental voice frequency, jitter, shimmer, and neutralized noise energy. A questionnaire was applied to measure aspects related to vocal self-image.
RESULTS:
in the auditory-perceptual analysis, a statistically significant difference was found between the groups regarding roughness (p=0,006) and strain (p=0,02), while the acoustic analysis showed no difference between the groups. The vocal self-image report, in both groups, highlighted the perception of being off-key.
CONCLUSION:
when comparing the groups, vocal changes were more common in professional actors, which suggests this group experiences vocal overload, which is a warning for the need for developing voice training for actors.
