Spectrographic analysis of male actors鈥?voices showed a cluster, the 鈥渁ctor鈥檚 formant鈥?(AF), which is related to the perception of good and projected voice quality. To date, similar phenomena have not been described in the voices of actresses. Therefore, the objective of the current investigation was to compare actresses鈥?and nonactresses鈥?voices through acoustic analysis to verify the existence of the 鈥淎F鈥?cluster or the strategies used to produce the performing voice. Thirty actresses and 30 nonactresses volunteered as subjects in the present study. All subjects read a 40-second text at both habitual and loud levels. Praat (v.5.1) was then used to analyze equivalent sound pressure level (Leq), speaking fundamental frequency (SFF), and in the long-term average spectrum window, the difference between the amplitude level of the fundamental frequency and first formant (L1 鈭?#xA0;L0), the spectral tilt (alpha ratio), and the amplitude and frequency of the 鈥淎F鈥?region. Significant differences between the groups, in both levels, were observed for SFF and L1 鈭?#xA0;L0, with actresses presenting lower values. There were no significant differences between groups for聽Leq or alpha ratio at either level. There was no evidence of an 鈥淎F鈥?cluster in the actresses鈥?voices. Voice projection for this group of actresses seemed to be mainly a result of a laryngeal setting instead of vocal tract resonances.
