Teamspeak
From The RadioReference Wiki
Teamspeak is a software application that allows you to use voice communications to talk to others on the Internet. Since RR users typically will be using Teamspeak to listen to scanner audio feeds, this document does not describe how to set up your transmit audio. This document assumes that the computer you are installing Teamspeak on already has working audio.
