I use a Cepstral voice, with the swift commando.
swift "hello"
Some Ubuntu updates ago this didn't work anymore. The solution was to use an OSS wrapper (If I understand it well).
padsp "hello"
With the most recent update to Ubuntu 22.04 this also doesn't work anymore:
pw@pw-ubuntu:~$ padsp swift "hello"
ERROR: ld.so: object '/usr/\15366LIB/pulseaudio/libpulsedsp.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
ERROR: ld.so: object '/usr/\15366LIB/pulseaudio/libpulsedsp.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
oss_audio: failed to open audio device /dev/dsp
Is there a way to make my cepstral voice work again?
The file '/usr/lib/x86_64-linux-gnu/pulseaudio/libpulsedsp.so' does exist
This output might be of interest (I don't understand it myself...):
pw@pw-ubuntu:~$ sudo modprobe libpulsedsp
[sudo] password for pw:
