In this tutorial, we will guide you through the way to set up Voice Changer Software Diamond 7.0 (VCSD7) to automatically change voice for online voice communication on Psi.

What is Psi?

Psi is an instant messaging application for Windows, Linux, and Mac OS X that connects to the free, open Jabber IM network (also known as XMPP).


In this tutorial, Psi application - an XMPP client - will be used to make an example. You should have Psi installed and set up probably in your computer first. Check detailed information from website.
