Abstract:This paper discusses the application of artificial intelligence in oral English teaching in higher vocational colleges. Firstly, it expounds its importance, including meeting students' individualized learning needs, increasing oral practice opportunities and improving teaching efficiency. Then, the four-dimensional application strategy of "technology optimization-teacher empowerment-teaching integration-student guidance" is put forward, including building a cooperative mechanism between production and teaching, implementing a hierarchical empowerment plan, reconstructing classroom teaching forms and establishing a three-dimensional guidance system. Finally, the development strategies are given from the perspectives of technology adaptation, teacher training, resource construction, ethical concern and integration of production and teaching, aiming at promoting the deep integration of artificial intelligence and oral English teaching in higher vocational colleges and improving the teaching quality and students' professional English communication ability.
