The Festival ebuild does not work out-of-the box with alsa: # echo "Test" | festival --tts Linux: can't open /dev/dsp You need to create a .festivalrc that contains (I also attached it, because I know it's not the prefered way to copy&paste stuff): (Parameter.set 'Audio_Command "aplay -q -c 1 -t raw -f s16 -r $SR $FILE") (Parameter.set 'Audio_Method 'Audio_Command) Then it works just fine. "aplay" comes with media-sound/alsa-utils, so we should make it a dependency for festival when alsa is enabled.
Created attachment 151861 [details] ~/.festivalrc for alsa
I put the suggested Parameter.set commands in /etc/festival/siteinit.scm which might be a better place for them. There are already some examples there, but not with aplay.
This is fixed, thanks to Solar.
