The current project is designed as phase 1 study conducted to improve/enhance normal voice. Fifteen Thirty non-treatment seeking individuals, with no identifiable vocal pathology on laryngeal examination, will be randomized to one of two groups; 1) Voice therapy delivery without App (control/standard of care), 2) Voice therapy delivery with app (experimental). Participants in both groups will attend weekly voice therapy sessions (for 6 weeks) with the PI and Co- I (Joseph Stemple). Control group participants will be provided with an audio file of the exercises, and an exercise log sheet to track progress. Experimental group participants will use the smartphone app, which allows participants to record home practice sessions in real time and upload sessions to the app server for the clinician to access and track. Three-wave surveys will be conducted at the baseline, four weeks and 6 weeks after the intervention. Other data sources include study administration, exercise logs, app data, and clinical assessment.
