Does anyone out there know of a decent Text-To-Speech chipset for use with a microprocessor based project? I've been looking around for a couple of days and the best I have found so far (based on web voice samples) is the RCSystems RC8660 http://www.rcsys.com/chips.htm. If you listen to the voices generated, they still sound very mechanical. I have devices (cell phone and GPS) that have voices in them that sound much better, but I think they may be pre-recorded. I would like to avoid using pre-recorded voices because I will need the flexibility to change the words being spoken in real-time through the program.
Thanks in advance,
Brendan
