Anyone using data from the Speech Accessibility Project must sign our general data use agreement.
If you'd like to use our data, please submit your signed agreement and a one-page proposal about your plans for the data to the Speech Accessibility Project team.
The current data package includes 1,090 hours of recorded speech (as .wav files) from about 1,130 participants, including those with ALS, cerebral palsy, Down syndrome, Parkinson’s disease and those who have had a stroke.
The download also includes text of the original speech prompts and a transcript of the participants’ responses. A subset includes
annotations describing the speech characteristics and how they affect participants.
