Ventrilo (also known as Vent) is a voice communication program allowing users to connect to a central server and chat with other users much like a conference call. This is essentially voice over IP technology, and in video game terms can often mean the difference between a successful raid run and or a complete wipe. Ventrilo users can count on no lag, amazing codecs and great stable performance. Ventrilo is definitely one of the industry's leading players in VoIP.

Teamspeak (also known as TS) is a communications tool that uses the internet as a highway for delivering clear communication. Teamspeak was originally targeted toward the gaming community.

MohawkVoice (also known as Mohawk) is the next generation in computer based voice communication. The application requires far less computer resources compared to any voice competition. This reduces game lag caused by low FPS due to computer resource consumption by their voice over IP software. While requiring less resource, it continues to provide high quality audio. Mohawk gets the job done without interfering with your productivity, or lack thereof

MumbleVoice (Also known as Mumble) is a voice over IP application primarily designed for use by gamers. It has a very simple administrative interface and most of the engineering effort is put into sound quality and low latency. Mumble uses Speex not only as a voice codec, but also for noise reduction and automatic gain control. From version 1.2 CELT is also supported. Mumble is optimized for low latency, resulting in faster communication. Mumble incorporates echo cancellation, which permits the use of speakers as well as headphones. With some games, like Battlefield and Call of Duty on Windows, a plugin lets you hear the positional audio of other players.
