yuyin.io — Master Chinese pronunciation with AI-powered feedback

Hi Product Hunt community! 👋 I'm Greg (欧利), creator of yuyin.io. As someone learning Chinese, I found that getting accurate feedback on pronunciation was one of the biggest challenges. That's why I built Yuyin - to provide instant, detailed feedback on Chinese pronunciation using AI. Key features: - Real-time pronunciation assessment with scores for accuracy, fluency, and so on - Adaptive difficulty levels from beginner (HSK1) to advanced (HSK5) - Custom phrase input for practicing specific words or sentences - AI conversation partner for speech practice - Demo available without registration The app uses Azure Services for pronunciation analysis and ChatGPT to generate practice phrases and conversations. All features are optimized for Mandarin Chinese learners at any level. I'd love to hear your feedback and answer any questions! Happy to discuss both the learning and technical aspects of the project. Try it out at yuyin.io 🎯 What other features would you find helpful for language learning?

Hey Grigorii, thanks so much for creating this. You're right, the feedback is so crucial. sometimes I'll be saying something exactly as I learned it (so I think) and no one understands me. This will be immediately added to my Mandarin practice. Also where can I find more information explaining the different forms of evaluation on my pronunciation; like how can I get 100 fluency but be 50% Accurate?
