Summary

This study aims to observe the physiological effects of two different Semi-occluded vocal tract (SOVT) exercises in the larynx when they are executed by individuals with constant vocal effort and without vocal pathology.

Conditions

  • Voice

Interventions

OTHER

Resonance tube

Participants will phonate into a tube (10cm length 4mm inner diameter) during 5 minutes. They will produce series of the vowel /u/ into the tube. They will be asked to maintain the same pitch and loudness as they did in the baseline samples. They will be perceptually controlled by experimenters. When performing the exercise, the participants will be instructed to phonate with ease voice and to sense vibrations in the anterior face and the mouth.

OTHER

Tongue trill

Participants will produce series of a similar /r/ Spanish sound during 5 minutes. They will be asked to maintain the same pitch and loudness as they did in the baseline samples. They will be perceptually controlled by experimenters. When performing the exercise, the participants will be instructed to phonate with ease voice and to sense vibrations in the anterior face and the mouth.
