Provided by the present invention is a virtual character-based artificial intelligence interaction method that is used to solve the technical problem wherein the interactive effect for artificial intelligence in the role of an assistant is poor due to a lack of emotional characteristics in interaction information responses. The embodiments of the present invention comprise: acquiring, from a corpus, a corpus resource for a role and performing vectorization processing so as to form a role corpus for the role; by means of a neural network model, performing natural language semantic recognition on the role corpus to form a determined role, and forming an emotional characteristic for statements by the determined role, then forming a personality characteristic for the determined role. The virtual character-based artificial intelligence interaction method of the embodiments of the present application combines text words or emotional control information of an interaction information input, and, by means of a manner of natural semantic recognition, creates an artificial helper having a personality; the present invention reduces human involvement on a large-scale, reducing the workload in development while producing an artificial intelligence helper having more natural emotions. The present invention further comprises a virtual character-based artificial intelligence interaction device.
