If you really insist, it can be hamfisted into IRC: https://www.youtube.com/watch?v=0R--_ATzE6o. (Though besides the official PoC https://github.com/asiekierka/voirc and my reimplementation https://spectra.video/w/vBd8cUmo9yYD5CtKbyjrL6, I have never seen this actually being used).

VoIRC is a joke project. It encodes your voice to base64 and sends that to an IRC channel at a rate that would get you kicked off most servers for spamming. Saved you a click.
