How to speak in Dota 2?

By default, the microphone is assigned to the «G» key, but at any time, like any other function, you can reassign it. To speak in the game, hold down the «G» key and speak into the microphone. If you want to change the key for voice chat, go to the game settings and find the «Controls» section. Then select «Voice Chat» and click on the «Change Key» button. Choose the desired key and save the changes.
