Take care to use drivers from the config matching your installed drivers.
By default it uses:
- sound driver: genericDriver (via sox, could configured in settings.conf)
- speech driver: speechdDriver
- speech driver: genericDriver (via espeak or espeak-ng, could configured in settings.conf)
- braille driver: brlttyDriver (WIP)
