JustMed, Inc. v. Byce
JustMed Inc. no longer exists, but other companies and non-profits exist to provide speech to people who can't speak on their own. Until recently, there was only a few synthetic voices available, you may be familiar with one of them if you have heard Steven Hawking talk.
There is a project called VocaliD, introduced at TED which aims to collect millions of voice samples and combining with with disordered speakers' voices to synthesize a unique digital voice for each person, so that users of this technology can have their own personal sound.
You can donate voice samples today.
