    SOVTE has been widely used in voice clinic. Estimates of time to perform the technique with a flexible latex tube are still unknown. This study aimed to investigate the immediate effect of flexible latex tube immersed in water on amateur singers after 1, 3, 5 and 7 minutes, considering: (a) the singers' self-assessment regarding voice and vocal effort; (b) acoustic parameters; and (c) auditory-perceptual parameters of voice quality.Twenty nine amateur singers (14 women and 15 men) performed the exercise with latex tube (35 cm X 0.9 cm) in one 1-minute set and three 2-minute sets. Data collection was conducted before and immediately after each set using sustained emission of vowel [a].Women and men were considered separately. Vocal self-assessment showed a statistically significant increase in negative sensations after 7 minutes of exercise for women. Auditory-perceptual analysis indicated voices were perceived more often as "equal" comparing pre exercise with first minute set and more often as "better" in the third and fifth minutes comparing with pre exercise only for women. The other parameters showed no significance.The exercise with flexible latex tube in amateur singers promoted improvement in vocal quality after 3 and 5 minutes for women. Also, the women presented significant negative sensations after 7 minutes. Immediate effect on the analyzed parameters was not observed in men.Copyright © 2021 The Voice Foundation.
