Summary

The goal of this clinical trial in voice professionals with both genders aimed to verify the changes in the vocal range profile and the changes in the glottic and vocal tract configuration for more efficient phonation after applying the adapted Lee Silverman Method and the addiction of lung volume recruitment technique in acoustic and structural analysis.

Detailed description

A cross-over randomized trial with two arms-the Lee Silverman Method and the addiction of lung volume recruitment technique (LVRT)-will be conducted with voice professionals to assess the effects of both interventions on the acoustic, perceptive, and visual aspects of voice and their impact on respiratory muscle strength.

Conditions

• Voice Quality
• Singing

Interventions

Type	Name	Description
PROCEDURE	Adapted Lee Silverman Method	Exercise protocol with 6 steps that the voice professionals adapted from Lee Silverman Method
DEVICE	Lung volume recruitment technique - LVRT	The adapted Lee Silverman Method will have a addiction of LVRT technique. Lung inflation begins, reaching an optimal inspiratory peak of 30 cmH2O. From this point, the sound /HA/ begins to be emitted until the most comfortable low sound, where the emission should be maintained for as long as possible, making sure that this time is not less than 12 seconds, trying to emit a high and comfortable vocal intensity. When performing the emissions, the mouth should be kept wide open with the tongue, jaw and neck relaxed, repeating 5 emissions in 3 series. Between series, the participant will be instructed to drink 50 ml of water exactly as in the previous emissions.
