Abstract

The invention relates to the field of natural language understanding, and provides a voice understanding method in an embodiment, which can be used in voice understanding equipment arranged on a cloud side or an end side to understand voice information of a user and identify a target application corresponding to the intention of the user in the voice information. The voice understanding method comprises the following steps: acquiring voice information of a user, respectively identifying intention of the voice information and slot values in the voice information according to intention information and slot information from a plurality of registered applications stored in a comprehensive voice library, and matching applications corresponding to the voice information according to the intention of the voice information to obtain a voice understanding result; and the intention of the voice information and the slot value in the voice information are transmitted to the corresponding application. The voice understanding method can support flexible expression of a user, can be adapted to all registered applications, does not need to re-collect data, label data and train a model when adapting to a new application, and has the advantages of short adaptation period and low cost.

Description

technical field [0001] The invention relates to the technical field of natural language understanding, in particular to a speech understanding method. Background technique [0002] Speech understanding systems have been widely used in various scenarios, such as smart phones, smart homes, smart cockpits, etc. The speech understanding system can understand the user's voice input, recognize the user's intention, and enable the user to control related functions through voice commands. A speech understanding system usually accesses multiple applications, so that a user can control various functions of multiple applications through a speech understanding system. [0003] In a method in the prior art, a newly accessed application defines a semantic expression template, and the speech understanding system builds a semantic understanding model dedicated to the semantic expression template, so as to realize the adaptation between the speech understanding system and the application.
