Mandarin Chinese Tone Drill is designed to help you test and practice your knowledge of Mandarin Pinyin and tones. When you click the Play button on the toolbar, the system randomly plays the pronunciation of a Chinese character. After your listen to it, you can press one of the tone buttons to check. You can also click the Show Pinyin button on the toolbar to view the Pinyin corresponding to the pronunciation.
