The current data package includes 771 hours of recorded speech (as .wav files) from about 850 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.
