Use this tool to add tone marks to pinyin or to convert tone number (e.g. hao3) to tone marks.

Although you can use the red buttons to add tone marks, we highly recommend you use the number method (e.g. hao3) for speed and placement of the accent above the correct vowel. [Hint: Type "v" for "ü"]
Note: You do not need to use this tool to enter pinyin in this dictionary.
