There is a Welsh language voice for it, and I have created a script that processes Cornish text doing a series of replaces to make it conform to Welsh spelling rules.
It would be possible to get espeak to speak Cornish directly by creating a Cornish voice for it, and I did start doing this a long time ago, but unfortunately lost this work along with my previous laptop.
The GUI launcher currently only works in Linux-compatible systems, because it launches espeak via the command-line via the Python os library. However espeak itself is also available for Windows and I will adapt the script to work on Windows dreckly.
