The "원어공: 3단계 학습시스템 영어회화" program by MetaCube Co.Ltd focuses on teaching English conversation skills through a unique learning system. This system, patented under registration number, emphasizes memorizing English through speaking rather than just memorization. The key lies in its 3-step learning system.

In the first step, users engage in 10-minute lectures on word association, enabling them to grasp the principles of speaking English by connecting words themselves. Moving to the second step, users interact with Korean artificial intelligence for review, reinforcing English speaking through vocal repetition of learned content. Finally, in the third step, users converse in English with American artificial intelligence, gaining practical experience in English conversations.
