Text-to-speech not working in xbox games

See if this works for you.

How do you talk to Minecraft support?

Minecraft includes an option to use text-to-speech for chat during any game session. To enable text-to-speech for chat: Use the Accessibility Menu in Settings to enable text-to-speech for chat.
Use the keyboard shortcut Ctrl+B at any point during a game session to enable text-to-speech for chat.

Hi Jeremie,

Hi Jeremie,

Thanks for reaching out to the forums. We understand you are having issues with text to speech. We recommend looking over the

guide for game chat transcription. You can also try disabling it and then re-enabling.

Thanks,

How are you, David?

Could you upload a screenshot of the options you see? Do not post any personal information.

Another thing that this function is only available to be used on Xbox Party

To turn that on:

1. Press the Xbox button to open the guide.
   
2. Select Profile & system > Settings > Ease of Access > Game and chat transcription.
   
3. To transcribe other party members’ voices into text, select the Speech-to-text checkbox.
   
4. To have your chat text read aloud to other party members, select the Text-to-speech checkbox. To choose the voice that other people will hear when your chat text is read aloud, select one of the available voices in the Text-to-speech voice menu.
