Attached is a patch that makes Festival work with Linux (ALSA) by
default… but it's a bit odd that we'd've been shipping a ‘broken’
Festival from day 0?
(TIL that our default Linux-Libre configurations enable legacy OSS
emulation so this could probably be made to work with the right
modprobes. Still, this should not be required without good
reason, and plenty of OSS-free kernels exist.)
I'd like to hear from existing Festival/Guix users if any actually
do.
Until then, you can easily hack around it:
$ cat <<EOF > ~/.festivalrc
(Parameter.set 'Audio_Method 'Audio_Command)
(Parameter.set 'Audio_Command
"aplay -q -c 1 -t raw -f s16 -r \$SR \$FILE")
EOF
$ echo sup | festival --tts
From [0] of all places. aplay is part of alsa-utils.
Kind regards,
T G-R
