The only pronunciation app that explains your errors in Chinese
Most Mandarin speakers share the same 5–6 problem sounds. Once you know which ones you have, fixing them is straightforward.

“I knew the answer before anyone else in the room. I just let someone else say it.”
Accent anxiety is real.
The fix is specific.
Most apps give you a score. Qiaoyin tells you why the error happened — in Chinese — and what to do about it.
Read a sentence. Ten seconds. That’s all we need.
Every word lights up — green, gold, or red. You see exactly where you landed and where you slipped.
Not ‘try harder.’ Not ‘practice more.’ We show you which Mandarin habit caused the error and how your mouth should move differently.
01
Other apps say ‘your TH is wrong.’ We say ‘you’re using the /s/ tongue position because Mandarin doesn’t have dental fricatives — here’s where to put your tongue instead.’ And because the reason you say /s/ is Mandarin, the explanation is in Mandarin.
02
Every piece of feedback traces back to one person: a trained Chinese-English linguist with 10 years of experience as an interpreter and pronunciation coach. Ben has been keeping notes on Mandarin speaker errors for a decade. When you say /s/ instead of /θ/, or drop the final -t in ‘product’, or flatten a diphthong — he’s seen it before and written down the fix.
03
Every session is scored and saved. Over time you’ll see exactly which sounds are improving, which still need work, and how far you’ve come since you started.
“I’ve been in the US for 8 years. No one ever told me WHY I say /s/ instead of /th/. This app showed me in two minutes — and explained it in Chinese.”
“After three weeks, my team stopped asking me to repeat myself in meetings. That was the moment I knew it was working.”
“I’ve tried ELSA, BoldVoice, all of them. This is the only one that understands what it’s like to think in Mandarin and speak in English.”

Ben spent ten years as a Chinese-English interpreter, sitting in rooms where the smartest person at the table wasn’t heard because of how they sounded. He started keeping notes on every error pattern he saw. This app is those notes.
