Lee Ridley has cerebral palsy. In his case, that means he has difficulty walking and can't speak. So what do you do for a living then? Stand-up comedy seemed like a good choice to Lee, because, as he says himself, people laugh at him anyway. 😀
iPad is an important part of his life as it gives him a voice he wouldn’t otherwise have. He uses an app named Proloquo2Go. It’s a speech synthesis software that he can write pre-recorded stuff in as well as use for improvised speech.
Look at the video of his performance on Britain’s got talent.
