English learning solution completed
with Silicon Valley’s technology

Learning a language is not just about reading texts or watching videos. Much like the way we learn our native language, it requires a lot of iterative input and output, and accurate correction. Speak develops all the necessary functions and provides unlimited access to make this happen.

Step 1
Today’s Lesson

Learn expressions through the teacher’s detailed explanations

Step 2
Speaking Practice

Practice until it feels natural to you

Step 3
Conversation Simulator

Practice speaking to an AI to help prepare for real-life situations

The Three-Step
Learning Method

Each lesson consists of three stages: “Today's Lesson,” “Speaking Practice,” and “Conversation Simulator.”

Through each course, you will be able to say more than 100 sentences aloud in English in 20 minutes per class, allowing yourself to make expression you’ve learned your own without knowing it.

Repetitive Patterns To Learn Expressions Rather Than Sentences

Speak's “Smart Review” automatically saves learned English patterns to review items and provides review classes.

The “interval iteration” learning algorithm guides reviews to be performed at the optimal timing, helping users remember the expression.

Most English education services provide a review function. However, it is only repeating the learned sentences so it can be memorized. But it’s difficult to apply those sentences in real life. For those who have struggled with this problem, the smart review function will be of great help.
