With the deep integration of AI technology and education

the paradigm of college English teaching is transforming from tool assistance to ecological reconstruction. This study breaks through the linear thinking of technology application

and focuses on exploring the three-dimensional breakthrough path of English teaching innovation in the intelligent education environment. Firstly

it uses the intelligent hierarchical teaching system to break the dilemma of "standardized output"

and construct the dynamic personalized learning graph. Secondly

with the help of immersive multi-modal resource platform

the spatial and temporal barriers of language learning are removed

and the cognitive enhancement from plane input to three-dimensional interaction is realized. Thirdly

it focuses on the cultivation of teachers' intelligent education ability

and facilitate the paradigm shift in the pedagogical relationship from knowledge transfer to intelligent symbiosis. It is found that AI-enabled English teaching innovation needs to go beyond the initial stage of technology superposition to form a synergistic effect in data-driven accurate diagnosis

emotional human-machine collaboration mechanism

cross-cultural digital quality cultivation

and finally build a new teaching mode with both language acquisition rules and intelligent technology characteristics

thus providing a reproducible practice model for the digital transformation of higher education.
