This study examined the effects of Flow Phonation Voice Exercises on vocal measures in undergraduate student singers. Whereas these exercises have provided positive outcomes in individuals with vocal hyperfunction, the use of these exercises in potentially enhancing the singing voice has not been explored. A total of 10 participants were randomly assigned into an experimental group (n = 6), that received 5 sessions of the Flow Phonation Voice Exercises across 5 weeks, and a control group (n = 4) which did not receive the treatment. Changes in auditory-perceptual, acoustic, subjective respiratory, quality-of-life and fatigue related measures compared across two groups. Results indicate statistically significant differences in Singing Voice Handicap Index and perceptual singing voice quality and a positive trend toward improvement in Vocal Fatigue Index in the experimental group alone. The results suggest positive outcomes of the use of these exercises. Small sample size and COVID-19 related methodological constraints should be considered while interpreting these results.
