Convert syllables (Zhuyin ↔ Pinyin)
This maps syllables from one notation to the other; it does not convert Chinese text. Look up the reading of a character in a dictionary (e.g. the Taiwan Ministry of Education’s Revised Mandarin Chinese Dictionary).
Separate syllables with spaces. Pinyin can use tone marks or numbers (ni3); type v for ü.

Spelling rules (notes of the Hanyu Pinyin scheme)
- The syllables 知 蚩 詩 日 資 雌 思 are written with i: zhi, chi, shi, ri, zi, ci, si (in Zhuyin only ㄓ ㄔ ㄕ ㄖ ㄗ ㄘ ㄙ).
- ㄦ is written er, and r when it ends a syllable (e.g. 兒童 ertong).
- ㄝ on its own is written ê.
- Finals starting with ㄧ, as syllables on their own, are written yi, ya, ye, yao, you, yan, yin, yang, ying, yong.
- Finals starting with ㄨ are written wu, wa, wo, wai, wei, wan, wen, wang, weng; ㄨㄥ after an initial is written ong.
- Finals starting with ㄩ on their own are yu, yue, yuan, yun (dots dropped); after j, q, x they are ju, qu, xu (dots dropped); after n, l they keep the dots: nü, lü.
- iou, uei, uen after an initial are written iu, ui, un (e.g. niu, gui, lun).
- The tone mark goes on the main vowel, and the neutral tone is unmarked; in iu and ui it goes on the second letter (e.g. 牛 niú, 水 shuǐ).
- When a syllable starting with a, o or e follows another and the boundary is unclear, separate them with ’ (e.g. 皮襖 pi’ao).
Practice
This practises the notation; not every syllable has characters in every tone.
How to use
- Type Zhuyin or Pinyin with spaces between syllables to see the other notation (e.g. ㄓㄨˋ ㄧㄣ → zhù yīn).
- Check how initials, finals and tones are written, and the spelling rules, in the reference tables.
- Choose a question type and range, start the practice and pick one of four answers. You can retry only the ones you missed.
FAQ
Can it convert Chinese text into Pinyin?
No. It compares the notations syllable by syllable. Many characters have more than one reading, so look up readings in a dictionary (e.g. the Taiwan Ministry of Education’s Revised Mandarin Chinese Dictionary).
Where does the tone mark go?
In Hanyu Pinyin it goes on the main vowel and the neutral tone is unmarked; in iu and ui it goes on the second letter (牛 niú, 水 shuǐ). In Zhuyin the first tone has no mark, ˊ ˇ ˋ follow the syllable and the neutral-tone dot ˙ comes before it.
Why are ㄧㄛ (yo) and ㄧㄞ (yai) included?
They are listed in the Taiwan Ministry of Education syllable table. Syllable tables from mainland China may differ slightly.
