Checking recognition support…

Scores are saved only on this device. Audio is not stored.

Recognition may use the browser provider's servers and require internet. We use the default microphone.

This is agreement with recognized text. Missing words can be recognition errors; the score does not assess individual speech sounds.

How is the score calculated?

Exact words get full credit; similar words get partial credit. Missing, replaced and extra words lower the score. Excellent requires all words in the right order. The 60/80% thresholds are experimental.
