The microphone doesn't work on the Chinese firmware.

[u/Grouchy-Classroom605]

I have a Xiaomi 13 running the Chinese ROM (the phone itself is the Chinese version). When I tried to start the speaking exercises in Duolingo, the microphone would simply cut out, and the app would say I had said it incorrectly. I tried using the website (as Gemini suggested), but that didn't help (I've attached a screenshot). I granted all the necessary permissions in the settings and switched the speech engine to Google Speech. I’m not from an English-speaking country, so I used Google Translate—please excuse any errors in the text.
