Abstract

The invention relates to a voice interaction method and a voice interaction system. The method comprises a preprocessing step, wherein input voice information is preprocessed, and voice clips are output; a semantic recognition step, wherein semantic recognition is performed on the voice clips output in the preprocessing step, and semantic information is output; a gender classification step, wherein the gender of a user is recognized from the voice clips output in the preprocessing step, and gender information is output; and a fusion processing step, wherein the gender information and the semantic information are fused to obtain personalized reply information to the voice information. According to the voice interaction method and the voice interaction system, a distinguishing reply can be given according to the gender of the user, so that user experience is improved, and the intelligent level of voice interaction is raised.

Description

technical field [0001] The invention relates to voice recognition technology, in particular to a voice interaction method and a voice interaction system capable of identifying user gender. Background technique [0002] In the in-vehicle dialogue system, the existing speech recognition technology can recognize the user's voice to a certain extent, but some topics involve the user's gender, and the current speech recognition technology is often difficult to give an answer that matches the user's gender based on the recognized text. [0003] The information disclosed in the Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or in any way to suggest that the information forms the prior art that is already known to those of ordinary skill in the art. Contents of the invention [0004] In view of the above problems, the present invention aims to provide a voice inter...
