Answer 2

Helen Keller is certainly the most famous example, but there are others who are both deaf and blind, or as their own community calls them, dead-blind. In such cases, though, the difficulties involving speech (using the voice) are mostly mechanical. One can not learn to speak easily if one can not hear proper sound and intonation. This did not prevent people from trying to teach deaf people to talk with their vocal chords, though. Alexander Graham Bell was one of many such people who believed that speech, for the sake of being speech, was superior to all other forms of communication, and that greatly hindered the Deaf community (and one can also argue the hearing community too) by preventing them from learning to communicate in the only way that truly seems reasonable for them to do so, i.e., with sign language.
