Can't open /dev/dsp

[MChhay]

I'm running Linux Mint 19 Cinnamon 3.8.8

I'm trying to run main/na_record and I get the following error

~$ speech_tools/main/na_record -f 16000 -time 5 -o test.wav -otype riff

Linux: can't open /dev/dspfor reading

From searching online, it looks like OSS is no longer supported. I've tried installing some OSS compatibility modules, but still haven't had any success in running ./na_record

It seems like the /dev/dsp error has already been fixed in festival: https://bugs.launchpad.net/ubuntu/+source/festival/+bug/662630
I didn't have any issues with playback in festival either.

There's a few old workarounds listed for festival here: https://wiki.archlinux.org/index.php/Festival#Usage_with_a_Sound_Server

Is there any way I can apply those workarounds to festvox? Or are there any other methods to get recording/playback in festvox to work?

Yep. Also for macOS. And the current bindings for macOS are deprecated so will disappear in a year or so. For Linux, ALSA should be fine and shouldn't be much trouble. If OSS is still a concern, maybe someone will take it on.

On a Debian Linux system and derivatives (e.g. Ubuntu, Mint) please install libasound-dev (sudo apt install libasound-dev) and then run again ./configure and make. (if you still get the same error please try starting from scratch uncompressing speech-tools on a clean directory)
