AI Chinese Pronunciation Coach
No one learns a language by passively turning pages in a textbook.
That is why I created Yin, the AI-powered Language coach designed to help you improve your Mandarin.

It includes three features:
- Pronunciation Exercises
- Multiple Choice Questions (MCQ)
- Flash Cards
The idea is to learn vocabulary that you can read and use in conversations.
Pronunciation Exercises: AI will correct your tones
The focus here is on improving my pronunciation of logistics and supply chain terms (my field of expertise).
For each word, we have:
- The word in Simplified Mandarin Characters: 合同
- The sentence used to practise my pronunciation: 我们需要在发货前签署这份运输合同。
- The English translation: We need to sign this transport contract before shipping the goods.
For beginners, we can even add phonetics (Mandarin pinyin) using the toggle.
How to practice pronunciation?
I just have to press the mic button at the bottom to record my sentence.

The recording is automatically sent to the backend for analysis that compares my pronunciation with the correct one.
A few seconds later, I received my feedback.
The feedback is quite detailed; it focuses on the words that you mispronounced.

It’s nearly like having a personal teacher correcting me in real time, except this one never gets tired.
