Exploration of Multi-round Dialogue Function of International Chinese Education Robot Based on LLM

In the process of international Chinese language education, issues such as the shortage of Chinese language teachers and insufficient input and output for Chinese learners are common. To enable learners to effectively engage in input and output activities based on their learning levels, this article attempts to integrate educational robot technology into the field of international Chinese education. Firstly, the article explains the form and function of robots; Then, based on the characteristics of robot technology, large language models, and multi-turn dialogue systems, it proposes the use of educational robots equipped with large language models specific to international Chinese education to assist learners. This research uses LangChain to connect a local Chinese resource library with a large language model, exploring the practical effects of educational robots equipped with this multi-turn dialogue function in international Chinese education, and compares it with the dialogue effects of general large language models. Finally, the article concludes with a summary and future outlook.
