Using voice rollercoaster together
An approximate pitch estimate from a sustained voiced sound.
A short way to begin
- Try a short, comfortable voiced sound.
- Explore a small high-to-low change if that feels easy.
- Treat gaps or jumps in the trace as device feedback, not a mistake by the learner.
Adapt this activity
Take turns together. Never strain, shout or hold your breath. Stop if the activity feels uncomfortable.
What the feedback means
The pitch estimate can be unreliable with noise, quiet input or irregular voicing. It is not a voice assessment or a measure of expressiveness.

Questions about this activity
Do I need to turn the microphone on?
No. Tap-to-play is available. Rhythm and turtle-pacing activities are based on deliberate taps rather than microphone analysis.
Is audio recorded or uploaded during this game?
No. These voice games analyze microphone samples in browser memory. The separate articulation record-and-replay feature is optional and is described in the privacy page.
Why does the response change between devices?
Microphones, distance, room noise and browser processing differ. Use sensitivity where available and interpret the display as approximate feedback rather than a clinical measurement.
