“I knew the answer before anyone else in the room. I just let someone else say it.”
Your accent is learnable. The errors are predictable.
Other apps give you a number. Qiaoyin tells you which Mandarin habit caused the error, explains it in Chinese, and gives you the physical fix.
Short sentences from meetings, presentations, and interviews. Under five minutes.
Sorted into three tiers: what blocks comprehension, what sounds unnatural, and what to polish. Each links to a specific Mandarin habit.
15 targeted lessons, daily challenges, and ear training — all built around your specific error patterns.
01
Other apps say 'your TH is wrong.' We say: 'Mandarin has no dental fricatives, so you're using the /s/ tongue position — here's where to put your tongue instead.' The explanation is in Chinese because the reason you make the error is Chinese.
02
A single number doesn't tell you what to fix first. Qiaoyin sorts your errors into Understanding (people misunderstand you), Clarity (you sound unnatural), and Polish (minor cosmetic patterns). You fix them in that order.

Ben spent ten years as a Chinese-English interpreter, watching the smartest person at the table go unheard because of how they sounded. Every feedback template, every coaching tip, every 'why this happens' explanation in Qiaoyin comes from a decade of those notes.
“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.
