TeamSpeak becomes the official voice chat for the Overwatch League

The Overwatch League is making TeamSpeak the esports league’s official voice chat supplier through 2022. In a three-year deal beginning with its 2020 season, the Overwatch League will integrate TeamSpeak’s technology to power all in-game communications in league matches. TeamSpeak is a provider of online communications services and tools for pro gamers.

The collaboration will also include a global marketing partnership at various Overwatch League events throughout the term, such as sweepstakes where fans could win tickets to league events and Overwatch League prizes. TeamSpeak will develop a custom solution for the Overwatch League based on their existing technology platform. TeamSpeak claims its technology provides ultra-low latency, high reliability, and high-definition audio for in-game communications. TeamSpeak tackles performance, security, and flexibility. TeamSpeak says its software has been downloaded more than 125 million times this year.
