What this trial is about
Parkinson's disease often causes speech and voice impairments, such as reduced vocal loudness and decreased speech intelligibility, which significantly impact the quality of life for patients and their families. The Lee Silverman Voice Therapy-LOUD (LSVT-LOUD) is a specialized, evidence-based speech therapy protocol designed to improve vocal function. This study investigates the effectiveness of the LSVT-LOUD protocol in Turkish-speaking individuals with Parkinson's disease. The research evaluates objective changes in vocal loudness and speech quality, as well as the subjective therapy experiences of participants. By analyzing both clinical outcomes and patient feedback, this study aims to contribute to the clinical application and adaptation of LSVT-LOUD for the Turkish-speaking population
