🔇Can't hear Turtelino talk? Some phones (like Xiaomi/MIUI) need Text-to-speech enabled separately — check Settings → Additional settings → Language & input → Text-to-speech output.
🎙️Can't record yourself? Check that this browser has microphone permission — on some phones (like Xiaomi/MIUI) it's a separate toggle under Settings → Apps → [this browser] → Permissions → Microphone.
