Try this procedure, hope it helps. You can enable the Text Conversation Chat or Speech Conversation Chat features. To do this:- Go to the game's main menu and select the Settings tab. - Enter the Accessibility submenu. - Select Enable Text to Speech Chat or Enable Speech to Text Chat. To mute or unmute the microphone, highlight your Gamertag and press the OPTIONS button. In-game chat is enabled. You cannot hear party audio and the party cannot hear your voice. To switch to party audio, select [Party Settings] > [Chat Audio].

Hope I helped and see you soon
