Dragon Dictate is commercial software that allows a computer user to dictate to programs and it converts a users speech into text.Going the other way from E-Book to audible speech can be done with free software developed by Ray Kurzweil for the American Society for the Blind.
If that BLIO program interests you or you know somebody perhaps in a nursing home who could make use of the program, you can download it from link below.
I heard about that software on SDPB-Radio a few years ago and tried it more or less as a curiosity, It worked surprisingly well. I then more or less forgot about it, but now have friends with severe vision problems or bored to tears in a nursing home and nursing home activity people have expressed interest in the program. Of course, as they say, "Your mileage may Vary".
