Construction and Innovative Application of Intelligent Agents in College EFL Teaching

Artificial intelligence has brought unlimited possibilities to education. Based on the Deepseek large language model and the Dify agent platform, this paper uses RAG, TTS, NLP and other technologies to build multiple different types of college EFL teaching agents. While greatly reducing the teaching workload of teachers, it can also establish a one-to-one personal learning assistant for learners to help them learn flexibly and efficiently. Teaching practice shows that the college EFL teaching agent can better adapt to the teaching methods of the intelligent era. It is an innovative exploration of the digital transformation of college EFL course in higher educational institutions.
