Abstract: With the rapid development of artificial intelligence technology and the deepening of the“Digital China”strategy, the digital transformation of higher education has become a core topic in the reform of college English teaching in the new era. Traditional workplace English teaching has obvious shortcomings in terms of standardized content, feedback, and personalized guidance, making it difficult to meet the requirements of the digital age for cultivating versatile talents. This study is based on the theoretical framework of digital transformation, exploring the innovative path of empowering workplace English teaching reform with generative artificial intelligence technology. Taking the STAR behavioral interview model as the starting point, the“STAR+AI” theoretical framework is deeply integrated, and various intelligent tools such as DeepSeek, Doubao, and Youyan AI are integrated to achieve collaborative application. A four stage closed-loop teaching mode of“demand diagnosis → precise training → intelligent evaluation → optimization iteration”is constructed. This model provides a systematic theoretical support and practical paradigm for the digital transformation of specialized English teaching, and has important value in promoting the innovative development of foreign language education empowered by artificial intelligence.
