Abstract

The invention relates to a chat robot system based on voice recognition and a Rasa framework and a conversation method. The system comprises a voice service module and an intelligent assistant module. The voice service module comprises a voice recognition unit and a voice synthesis unit, and the voice recognition unit is used for recognizing input voice information and converting the input voice information into text information; the voice synthesis unit is used for converting the received text information into voice information; the intelligent assistant comprises a language understanding unit and a dialogue management unit, and the language understanding unit is used for performing user intention classification and entity extraction according to text information; and the dialogue management unit is used for maintaining and updating the dialogue state and action selection of the user and correspondingly outputting replied text information to the input of the user according to the understanding result of the voice understanding unit. The chat conversation of the robot is smoother, and the experience of the robot is improved.

Description

Technical field [0001] The present invention relates to the field of human-computer dialogue, and in particular, to a chat robot system and a conversation method based on speech recognition and RASA framework. Background technique [0002] Natural Language Treatment (NLP) is a field of computer science, artificial intelligence, linguistics concerned computers and human (natural) languages. By obtaining the semantics of the natural language, the purpose is to generate a semantic representation of a machine-readable natural language for chat robots. [0003] With the development of artificial intelligence, Internet and other technologies, chat robots apply multiple areas, in the fields of telecommunications, tourism, medical aviation, finance, etc., the effect is obvious. Artificial intelligence technology has broken through the original technical bottleneck of chat robots, and the practice proves that the use of chat robots can not only reduce a large human cost, but also signific...
