Teaching Autistic adults to speak

Is it possible to teach adults with autism to speak?

Answer:

Unfortunately, the simple answer is that we don’t know because there is no research evidence that tells us one way or the other. There are reports of individuals which indicate that it may be possible (see for example, Helping to unlock the secrets of autism), but what works for one individual may not work for another. Because of that we cannot make any predictions about particular individuals.  However, it is important not to assume anything. Experiences through work, reading of the research literature, and listening to the personal stories of Autistic people and their families lead us to think that we can’t predict what individual Autistic people can or cannot learn, and we shouldn’t give up trying to help them to learn skills. We shouldn’t be surprised by surprises.
