SOVT Trial Summary

This trial looked at how well people with different levels of vocal activity could improve their vocal range and stability after doing stretching exercises.

Who is the study for?
This trial is for adults over 18 without current voice disorders or professional vocal training. It's not for those with a history of laryngeal surgery, ongoing voice issues needing medical treatment, neurological or structural vocal fold problems, cognitive limitations impacting study participation, allergies to certain anesthetics, gastrointestinal/cardiac conditions, recent smokers (within six months), or past head/neck cancer.Check my eligibility
What is being tested?
The study tests whether straw phonation exercises can help extend the range of pitch and stabilize vocal folds in people who use their voices differently. Participants will perform these exercises to see if there are measurable improvements in their voices.See study design
What are the potential side effects?
Since this trial involves non-invasive voice exercises rather than medication or surgery, side effects are minimal but may include temporary throat discomfort or fatigue from the exercises.
