Interesting workaround ;) Pratically, the only modules to cheange from "alsa" to "oss" (for me) are: - espeak.conf - festival.conf - flite.conf - ibmtts.conf
But, for a n00b like me, it is not clear how the /etc/init.d/speech-dispatcher file should be adapted. Could you provide directly the adapted file?
