Usedeconobox, You would be amazed at what blind people can do. I have several blind friends who are superb pianists. Over the decades, several famous organist/composers have been blind, including one of the current Notre Dame organists, Jean Pierre Leguay. Some of my blind friends are also piano tuner/techs and can tighten action screws faster than I can! I think that there is speech software available for computers for this purpose.
