Now recruiting!
The Speech Accessibility Project is now recruiting U.S. and Puerto Rican adults:
- who have Down syndrome
- who have cerebral palsy
- who have amyotrophic lateral sclerosis
- who have had a stroke
People over the age of 18 are eligible. Unfortunately,
we cannot recruit participants from Illinois, Texas, or Washington at this time because of their state privacy laws.

Learn moreAbout the project
The project has unprecedented cross-industry support from Amazon, Apple, Google, Meta, and Microsoft, as well as nonprofit organizations whose communities will benefit from this accessibility initiative, to make speech recognition more inclusive of diverse speech patterns.
Today’s speech recognition systems, such as voice assistants and translation tools, don’t always recognize people with a diversity of speech patterns often associated with disabilities. This includes speech affected by Lou Gehrig’s disease or Amyotrophic Lateral Sclerosis, Parkinson’s disease, cerebral palsy, and Down syndrome. In effect, many individuals in these and other communities may be unable to benefit from the latest speech recognition tools.
