About this study

In plain language

This study tests devices that make speech louder for people with Parkinson’s disease or related disorders who have a quiet voice. It looks at how changes in speaking and device settings may help these devices work better for each person.

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.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Speak North American English as your main language.
  • Have a neurologist’s diagnosis of Parkinson’s disease or parkinsonism, a group of related conditions. A neurologist is a doctor who treats brain and nerve conditions.
  • Have changes in your speech or voice.

Who can't join

  • Have a history of other speech, language, brain, or nerve problems besides Parkinson’s disease or parkinsonism.
  • Have uncorrected hearing loss above 40 dB HL in both ears on the study’s starting hearing test. This is a measure of hearing loss.
  • Use a cochlear implant, a device placed by surgery to help with hearing.

Simplified for readability. The official criteria below are what the study team uses.

Official eligibility criteria

Inclusion Criteria: * Dominant speakers of North American English * Have received a neurologist's diagnosis of Parkinson disease or parkinsonism (e.g., PSP/MSA/PSP) * Present with changes in their speech/voice Exclusion Criteria: * History of any other speech, language, or neurological concern other than Parkinson/parkinsonism. * Uncorrected hearing loss that exceeds a threshold of 40 dB HL in more than one ear (as per baseline screening audiometry) and/or use of a cochlear implant.
