People who have vision, hearing or speech disabilities ("communication disabilities") use different ways to communicate. For example, people who are blind may give and receive information audibly rather than in writing and people who are deaf may give and receive information through writing or sign language rather than through speech. Similarly, persons with speech disabilities may use a speech generating device. The links below provide some helpful resources for communication related disabilities.
