Linux Voice Changer (Mumble, Team Speak)

It seems easy to change voice in Windows just like this tutorial https://www.youtube.com/watch?v=pmlYiK6fgX0 Unfortunately, Voicemod is not available on Linux yet. I've been searching for Linux Voice Changer and found this link 7 Best Real Time Voice Changer for Discord Apps 2020 Out of 7 Best Real Time Voice Changer provided, only 2 supported by Linux which is Mumble and Team Speak I've installed both apps, unfortunately, I still can't figure out how to change a voice. Should there is any good tutorial on it, please let me know.
