Abstract

Embodiments of the present invention provide a voice interaction-based context acquisition method and device, the method comprising: acquiring a scene image collected by an image acquisition device at the voice start point of this conversation, and extracting facial features of each user in the scene image; If according to the face feature of each user and the face database, it is determined that there is a second face feature matching the first face feature, then the first user identification corresponding to the second face feature is obtained from the face database, wherein , the first face feature is the face feature of a user, and the second face feature is the face feature of the user in the dialogue state stored in the face database; Dialogue, the context of the voice interaction is determined according to the current dialogue and the existing dialogue, and after the voice end point of the dialogue is obtained, the dialogue is stored in the voice database. This embodiment can improve the accuracy of acquiring the context of voice interaction.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of voice interaction, and in particular, to a method and device for acquiring context based on voice interaction. Background technique [0002] With the development of artificial intelligence technology, the development and use of intelligent voice interaction products have attracted much attention. Among them, intelligent voice interaction is an interactive mode based on voice input. Users can input their own requests through voice, and the product can respond to corresponding content according to the intention of the request. [0003] In the prior art, in an application scenario of an intelligent service robot, such as a welcome robot, a police robot, etc., there are often scenarios where multiple people interact with the intelligent service robot at the same time. When multiple people talk to the robot, if the source of the dialogue content cannot be identified, the context of t...
