Voice quality in actors

The aim of this research was to examine the relationship between the results of the voice quality self-assessment and the objective voice evaluation in the group of 37 professional theater actors from the City of Zagreb. The voice quality self-assessment was performed by using the Voice Handicap Index (VHI) questionnaire, and the objective evaluation included the acoustic analysis of the sustained phonation of the vowel /a/, carried out by using the PRAAT Program. In the self-assessment area, the highest average score was observed in the physical subscale of the VHI questionnaire (M=7.81), followed by the score in the functional (M=3.08), and emotional subscale (M =2.49), respectively. Among the items with the highest score were P2 item (The sound of my voice varies throughout the day) and the P7 item (I try to change my voice to sound different). The objective voice evaluation included the acoustic analysis of three variables: jitter, shimmer and the harmonics- to-noise ratio (HNR). Although the obtained mean values for all of the observed acoustic parameters were within the normal range, more detailed analysis revealed that in 20% of the subjects the acoustic measures exceeded the expected range. The results of the statistical analysis showed significant positive correlation between overall score on F subscale of the VHI and the observed acoustic variable HNR.
