We are the world's first interactive listening and speaking Chinese vocabulary learning platform.
It was developed by Foreign Language Teaching and Research Press, one of the biggest language publishing houses in China, and AI Speech, world-leading speech technology specialist.Respectively, they provide expertise in teaching Chinese to non-native learners, and state-of-the-art speech analysis technology.

To speak fluent Chinese, learners need to overcome difficulties with both pronunciation and tones. In Chinese, there are four major tones. Tones are of critical importance because the same syllable spoken with a different tone might mean something completely different! But tones can be difficult because most beginning learners have trouble distinguishing between them.
In the practice section of Ladder Chinese, our technology graphs learners’ tone curves for comparison with the standard tone curves. Any errors in tone are easy to see. By making learners’ own spoken tones into a visual image, Ladder Chinese gives learners a new tool – their own eyes -- to make mastering difficult tones much easier.
In addition to tones, some Chinese pronunciations can also be difficult for non-native learners, especially those sounds which don’t exist in English and other languages. When the system identifies a mistake in pronunciation or tone, learners are prompted to enter the difficult pronunciation window, where clear instructions for pronunciation are given by breaking the syllable into parts and using similar sounds in English to indicate the proper pronunciation.
Enabled by state-of-the-art speech analysis technology, Ladder Chinese is able to offer real-time pronunciation assessment and instructions, helping learners to speak Chinese accurately!
