How to Get Voice Chat to Work With "Starcraft II"by Nicholas Schrandt ; Updated September 22, 2017
In "StarCraft II: Wings of Liberty," players can participate in multiplayer missions and battles with friends or complete strangers through the Battle.net system. Players can choose if they want to fight cooperatively with each other against computer-controlled opponents, fight in teams against other players or play in free-for-all fights against each other. The voice chat feature allows players to communicate with each other vocally instead of having to rely on the typed chat function and in this fast-paced game, good communication can mean the difference between victory and defeat.
Launch "StarCraft II: Wings of Liberty" and sign in to your account by entering the information it requests.
Press the "Menu" button on the bottom, left corner of the main menu. A small window will appear in the center of your screen.
Click on the "Options" button at the top of the menu to open a new window.
Click the "Voice" tab on the left side of the new window to open all the options for the voice chat feature.
Check the box at the top of the window that is titled, "Enable Voice Chat." This will turn the feature on and allow it to be used during gameplay.
Check the box on the right side of the window under "Talking" that is titled "Enable Talking."
Press the "Start Test" button underneath the "Microphone Test" option and speak into your microphone. If the feature is working properly, it will replay what you say back through your headset or speakers. Press the "Stop Test" button when you have finished the test.
Press the "OK" button at the bottom of the window and then the "Return to Game" button at the bottom of the first menu.
