Abstract

Embodiments of the present invention provide a context acquisition method and device based on voice interaction, the method comprising: acquiring the current dialogue and continuous multi-frame pictures collected within a preset time period; acquiring the common target faces in the multi-frame pictures For the face image of each frame of picture, and according to the face image of each target face in each frame of picture and this dialogue, determine the first user feature of the target user who belongs to this dialogue; If it is determined in the database that there is a second user feature matching the first user feature, then the first user identification corresponding to the second user feature is obtained from the face and voiceprint database; If the dialogue is stored, the context of the voice interaction is determined according to the dialogue and the existing dialogue, and 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...
