【英文摘要】：
Intelligent virtual assistant, an innovative application of artificial intelligence and natural user interface, constructs an effective learning support system and is still in the exploration stage of research and application. This paper first analyzes the concept and key technology of intelligent virtual assistant, then studies its learning support from the analysis of function, application, and value, and finally puts forward the framework design and development analysis of learning support system which is implemented by a case. The results show that the intelligent virtual assistant can function personalized tutoring, interactive Q&A, situated learning etc., and promote the development of intelligent learning and personalized learning. Meanwhile, three developmental approaches of intelligent virtual assistant can meet the requirements of application development in different levels in education.
