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.

    I can’t hear the mandarin audio here:

      Hi, Toto.

      Unfortunately, we don’t currently have sound files for some of the radicals. However, since you’ve let us know it’s missing, we’re going to try and find a resource to add them in the future!

    This little thing on the side is making it unbearable to be on the site! Please do something about it! X)

      Hey, Jesse.
      Do you mean the bell? You can get rid of it by clicking on it and then you can choose to get notifications from Written Chinese when we release new blog posts 🙂

      • Jesse Shea

        Not the bell, the facebook, twitter, etc. bar. It is sitting right in front of text at half screen and just gets in the way…

        • Hollie Sowden

          Ah I see. I think because your screen is smaller it’s overlapping. Let me take a look, and I’ll see what I can do. Sorry it’s bothering you!

            Thanks, I see that there is a little arrow thing that pushes it in now; and there is then an arrow thing to push it back out. I don’t know why it was irking me so badly. 🙂

          • Hollie Sowden

            I was going to suggest the arrow, so I’m glad you found it! 🙂
