Questions
What does the score measure?
Pitch match compares your tone contour with a teaching guide. It is experimental feedback, not a check of words, consonants, vowels, or overall pronunciation.
Is tone sandhi included?
Yes: spoken pinyin reflects supported third-tone changes and 一 / 不 rules. You can review readings and adjust phrase breaks for context.
How long can my sentences be?
Up to 24 Chinese characters, in either script. The whole sentence appears on one pitch chart.
Is my audio uploaded?
No. Audio is processed locally for the current take. Saved history contains pitch traces and summaries. Privacy policy.
