Description
Summary:Semi-occluded vocal tract exercises (SOVTE) have shown to lead to more effective and efficient vocal production for individuals with voice disorders and for singers. The aim of the present study is to investigate the effects of a 10-minute SOVTE warm-up protocol on the actors’ voice. Twenty-seven professional theater actors (16 females) without voice complaints were audio-recorded while reading aloud, with their acting voice, a short dramatic passage at four time points. Recordings were made: the day before the show, just before and soon after the warm-up protocol which was performed prior to the show and soon after the show. The voice quality was acoustically and auditory-perceptually evaluated and quantified at each time point by blinded raters. Self-assessment parameters anonymously collected pre and post exercising were also analyzed. No statistically significant differences on perceptual ratings and acoustic parameters were found between pre/post exercise sessions and males/females. A statistically significant improvement was detected in the self-assessment parameters concerning comfort of production, sonorousness, vocal clarity and power. Vocal warm-up with the described SOVTE protocol was effective in determining a self-perceived improvement in comfort of production, voice quality and power, although objective evidence was missing. This straightforward protocol could thus be beneficial if routinely utilized by professional actors to facilitate the voice performance.
