About Lingko
So a stumble in speech never costs you a chance
Lingko makes speaking Korean less frightening.
The Problem
You study Korean, but speaking stays where it was
Reading and writing improve on your own. Speaking needs someone on the other side.
In a one-hour class, the minutes you actually speak are few.
You know the grammar, but the mouth does not open. That state lasts.
“I memorize more sentences, but my mouth still will not open.”
So we reversed the order.
What blocked people was not grammar but the first word — there was no one to say it to.
Instead of opening an app, we made the call come to you. At the time you set, the beaver calls first. When you hang up, what broke down is waiting for you.
What We Do
This is what we are building
Speech AI
We built and validated our own engine for calls and pronunciation analysis. Today it runs alongside a commercial pipeline.
Korean curriculum
We built a 13-step system ourselves. 10,636 words and grammar points are assigned step by step.
Learning data
We hold 2 million utterances from 37 countries. Error patterns by language feed back into the models.
You can talk with the beaver right now.
