Rockbox Voice Files
Voice files are now built daily automatically as part of the build system. You can find the voice files made available by the Rockbox project by following the extras link on the website menu. Any other voice files may or may not work, but the ones provided there are expected to and should always be tried before seeking support over IRC, the forums, or the mailing list, or attempting to file a bug.
Alternatively, you can use RockboxUtility
to make your own voice files.
