LEX - 10s AI English Speaking

English conversation is not decided by knowledge alone. It is decided by reflex.

LEX is an English learning app focused on 10-second response training.
Every day, you answer one prompt by speaking in English.

AI recognizes your voice, evaluates meaning, and provides instant feedback on expression.

It is designed for people who want to build practical English speaking skills efficiently in a short amount of time.

■ Why is speaking English so difficult?

You know vocabulary.
You understand grammar.
You have been studying English.

Yet when it is time to speak, you freeze.

The problem is not lack of knowledge.
It is the lack of training to turn thoughts into words instantly.

■ 10-second speaking training

When LEX speaks to you, you respond within 10 seconds.
You practice speaking English without overthinking grammar or vocabulary.

Your voice is automatically transcribed.
AI compares your answer with a model response and evaluates meaning.

It does not require perfect wording.
If the meaning is correct, it counts.

The focus is not perfection.
The focus is building the ability to express yourself instantly.
