Full Definition
Lee Silverman Voice Treatment (LSVT) is an evidence-based voice therapy approach developed specifically for people with Parkinson disease and other neurological conditions affecting voice and speech. The LOUD program emphasizes high-effort voice production to improve vocal loudness, pitch variability, and speech intelligibility. Treatment typically involves intensive sessions over four weeks, with specific protocols for vocal exercises, calibration of perceived loudness, and carryover to functional communication situations.
