Speech Amplification Devices for Parkinson Disease: Talker- and Technology-Driven Enhancements (NCT07599696)
🩺 Plain-English Summary (8th-Grade Level)
The proposed research aims to investigate the use of speech amplification devices as a potential treatment option for people with Parkinson's disease and related disorders who exhibit hypophonia, a voice disorder that affects over half of those with Parkinson's disease. By characterizing the acoustic and perceptual effects of speech amplification and identifying ways to optimize outcomes through talker- and device-specific enhancements, this project seeks to develop personalized, evidence-based treatment options for hypophonia. The current proposal will move this effort forward by systematically eliciting and modifying speech amplification device output that leverage both behavioral and technological approaches.
