Learn bopomofo typing, free

Words from Taiwan's Ministry of Education dictionary

Characters and words come from Taiwan's Ministry of Education dictionary, graded 1–7 against the Taiwan Benchmarks for the Chinese Language (TBCL), then cut into lessons of ten in the order they are actually used.

You always know which lesson you are on and how many are left — no guessing what to practise.

A lesson's results: keys per minute, accuracy, mistakes, time and longest streak

Dictationlisten, then type

Audio only — the prompt stays hidden. Listen, then type.

When Regular mode stops being a challenge, this is the stage above it. Every bopomofo, character and word lesson, and the timed test.

Missed symbols, tricky syllables, your trend

A per-symbol accuracy heatmap: the sounds you are shaky on, at a glance.

The pairs you most often confuse, the syllables you keep missing, how much you have practised and where it is heading — enough to find a weakness and clear it.

Statistics: the accuracy of every bopomofo symbol, the weak ones tinted
Confused symbols: each symbol you were asked for beside the key you pressed
Trends: speed and accuracy over three months
