Answers to the most common questions about the TongueTwister app. Nothing that fits? Just write us.
First aid
The app doesn't hear me — what now?
TongueTwister needs access to the microphone and speech recognition. Check under Settings → TongueTwister that both permissions are enabled, then restart the app once.
“Speech recognition is not available for this language”
Your device doesn't have the chosen language installed for dictation. Add a keyboard for that language under Settings → General → Keyboard → Keyboards — iOS then downloads its dictation support automatically and the language becomes available to the app.
The last word is missing from the recognition
Just keep speaking a beat longer before you stop — after stopping, the app briefly waits for the final result. That extra time doesn't count against you.
The AI generator doesn't show up for me
The generator for personal tongue twisters needs iOS 27 and a device with Apple Intelligence. On other devices the app hides the tile — all 410 curated tongue twisters, the coach and the videos still work.
The avatar (♀/♂) in the video doesn't match my voice
The automatic choice estimates your pitch — it's only an approximation. In Settings you can pin the clip set to ♀ or ♂ at any time.
How is the knot score calculated?
From your accuracy, your completeness of the target words and your speed. In short: the more your tongue stumbles (and the braver your pace), the higher the knot. The “?” symbol in the app explains all the details.
