Teamspeak is the market leader in group voice communication. It brought the idea of servers with user management. In addition, it is the first to have introduced two options: push-to-talk (PTT) and sound detection to turn on the microphone. Although it can be used for any type of audio conferencing, Teamspeak is appreciated for its low consumption of system resources, its ease of use and its many administration and moderation options. Today, its aging interface and price could cause it to lose market share.
