Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to compare the effectiveness of two voice therapy techniques, Resonance Tube Voice Therapy and the Traditional Smith-accent Method, in enhancing voice quality for adults diagnosed with non-organic functional dysphonia. Participants aged 15 to 60 who are native Arabic speakers will be enrolled based on a clinical assessment by a phoniatrician. The interventions will involve training using a semi-occluded vocal tract approach in water. The outcomes will be measured to determine which method yields better results in voice quality improvement.
