Abstract

An embodiment of the invention provides a context acquisition method and device based on voice interaction. The method includes acquiring a scene image collected by an image collecting device at a voice starting point of a current dialog and extracting face characteristics of each user in the scene image; if second face characteristics matched with first face characteristics exist according to face characteristics of each user and a face database, acquiring a first user identification corresponding to the second face characteristics from the face database, wherein the first face characteristics are the face characteristics of one user, and the second face characteristics are the face characteristics of a user in the dialog state saved in the face database; if a saved dialog corresponding to the first user identification is saved in a voice database, determining the voice interaction context according to the current dialog and the saved dialog and saving the current dialog in the voicedatabase after a voice end point of the current dialog is obtained. By means of the embodiment, the voice interaction context obtaining accuracy can be obtained.

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...
