Riot, after 17 years, finally adds team voice chat to League of Legends

Riot Games introduced team-wide voice chat in League of Legends with Patch 26.20, initially for North America and Oceania, requiring players to be Honor level 3 or higher to speak while others can only listen. The update also adds “voice skins,” improved noise cancellation, faster connections, and greater stability, with further regional rollouts pending.
