Not a tutor or ASR app
This is a one-phrase tone-practice preview. It does not chat, transcribe your words, or role-play a teacher.
One phrase · Northern reference
Practice “má” — rising tone
Listen to the reference, then hold the record button and say the phrase once. This browser preview checks recording conditions only; it does not score your tone.

Phrase 01
má
Meaning: mother · reference: Northern rising contour
A short synthetic guide tone demonstrates the rising direction; it is not a human pronunciation model.
Recording check before tone feedback
Use a reasonably quiet room. Your recording stays in this browser preview and is discarded when the check finishes.
Microphone permission is requested only when you start.
One bounded practice cue
Let the pitch move upward through the vowel.
This is an educational cue for the reference phrase, not a diagnosis of your recording. The preview has checked recording conditions only.
Claim ceiling
What this preview is — and is not.
Not a chatbot tutor. Not an ASR transcription app. No fluency guarantee. Recording check first; no tone feedback when the audio fails the check.
No fake feedback on bad audio
Very short, quiet, or clipped recordings receive a retry. No tone cue appears after a failed check.
No fluency guarantee
One educational cue and quiet-room scope. It does not promise fluent, native-like, or guaranteed speech progress.
Keeps the cue bounded: an observable practice action only — not anatomy advice or a medical assessment. Dialect and environment limits live in the methodology.
