Research-Backed, Science-Driven Learning Results

Keraft’s efficient business English AI teaching system is supported by peer-reviewed research published in international SSCI-indexed journals. An 8-week controlled experiment confirmed that AI-powered spoken English training can comprehensively improve learners’ speaking scores, learning motivation, and engagement compared to traditional classroom settings. Realistic business scenario simulations, tiered step-by-step practice, and real-time one-on-one feedback help learners break through the barrier of being afraid to speak, significantly boosting expressive confidence and learning enjoyment.

This research provides a standardized AI teaching solution for digital business English instruction across colleges and training institutions, making Keraft one of the most rigorously validated AIGC speaking practice tools available. It also earns strong recognition from enterprise clients, with multiple state-owned and private enterprises selecting it as their official designated spoken English training platform after competitive bidding, boasting extremely high client repurchase rates.
