Compare tones on the pinyin chart with audio
You can hear the difference between tones on the pinyin chart with audio on Chinese Boost. The chart plays recordings in both female and male voices. Tap a syllable to hear all four tones, or the one you’ve chosen in the toolbar. It’s free, with no account needed.

Choose all four tones or one tone in the toolbar.
The grid groups syllables by initial and final. Search for ma3, or enter 长 to find cháng and zhǎng. Selecting a syllable shows its parts and common characters for each tone, with links to the Chinese dictionary (词典).
Below the chart, you can test your listening with ten syllables per quiz and a score at the end. There are also recordings comparing sounds such as x and sh, and examples of tone changes in words.
