After testing voice chat in Heroes of the Storm, Blizzard has implemented the feature in the live game.
The company laid out its approach in a blog post, but the short of it is about what you'd expect: voice chat is optional, and the game has separate channels for team voice and party voice.
"If you're in a party, you'll automatically be added to your party's voice channel, and only party members will hear what you have to say." Conversely, "if you're in a partial party and using the party voice channel, you'll be unable to speak to or hear allies outside your party unless you switch to the team voice channel." By default, players have to opt-in at the start of a match to join the team channel.
Should you encounter any loud-mouthed ne'er-do-wells, there will be an "Abusive Voice" reporting option along with a new "voice silence penalty that's separate from chat silence penalties."
If a player is reported enough for voice violations, they can receive a silence that "will prevent them from speaking in team voice for the duration of that penalty. They can, however, still join the team voice channel to listen to allied comms, and can still join and use the party voice channel normally."
Be good to each other out there, and bring on the wombo combos.
