Survey of Speech-Language Pathologists’ Experiences with Speech Amplification Devices for Hypophonia in Parkinson’s Disease


The research lab in the Communicative Disorders and Sciences Department at the University at Buffalo is looking for speech-language pathologists who treat people with Parkinson’s disease to participate in an online survey. Specifically, this study is investigating speech-language pathologists’ experiences, perceptions, and opinions of the use of speech amplification technology for use with clients with Parkinson’s disease. We are interested in hearing from all S-LPs who meet our inclusion criteria (below), regardless of your direct experience with speech amplification technology.

You are eligible to participate if you:

  • are over the age of 18
  • consider English to be your primary language
  • are a registered speech-language pathologist in either the United States or Canada
  • have at least 2 years of experience treating clients with Parkinson’s disease.

The survey is expected to take 15 to 20 minutes and will include short answer, multiple choice, and open-ended questions. You will also be asked if you would like to be contacted in the future to help us recruit for a related study that will include individuals with Parkinson’s disease or parkinsonism who have experience using speech amplification devices. This research has been approved by the Institutional Review board at the University at Buffalo.


You may reach the IRB at (716) 888-4888 or email if you have any concerns.

Participants will be entered to win one of twenty $25 Amazon Gift Cards.
