Hi They work with both 4.61 and 5.0 although 5.0 works better than 4.61 does. Does the say program work by itself? If it does, and speech dispatcher doesn't, then there's likely a problem executing the command. In this case, edit dtk-generic.conf and at the end of the file, you'll find two debug statements. Uncomment them both, and change the line saying: Debug 0 to Debug 1 My debug lines look like: Debug 1 Debugfile /tmp/debug-dtk-generic Restart speech dispatcher and try to use it. It won't make it work, but this will generate a log file for the module. Send that log along so we can have a look at it.

I've tried both 4.61 and 5.0, and no speech. Are the two dtk-generic.conf files I have used meant to work with 4.61 or 5.0? Since they both seem to use the say program, would it make any difference?
