  • Python 3.6+
  • PyQt 5.10+
  • Sox (Linux package).
  • Working Microphone, Speakers and Sound System.
  • Working Sound Loopback Kernel Module

From https://github.com/juancarlospaco/pyvoicechanger#requisites

Make sure you have Python version 3.6 and later.

:~$ /usr/bin/python3 --version
Python 3.6.7

Python came preinstalled so no need to install, your 18.10 should have fulfill this requirement automatically.

Install the requisites.

sudo apt-get install sox python3-pyqt5 python3-pip

Install pyvoicechanger through pip then.

sudo pip3 install pyvoicechanger

Finally, you can launch voice changer by entering.
