Embodiment approach

[0145] Way 1: The time information carried in the speech recognition result is determined as a time tag corresponding to the user's speech.

[0146] When the voice recognition result carries time information such as today, tomorrow, what time, etc., this embodiment can be adopted.

[0147] Mode 2: The receiving time of the user's voice is determined as a time tag corresponding to the user's voice.

[0148] When the speech recognition result does not carry time information, this embodiment may be used to determine the time stamp of the user's speech.

[0149] Step 2: From each response result corresponding to the user's intention in the tree structure intention library, select the response result corresponding to the above time tag as the target response result.

[0150] In this embodiment, when selecting the target response result, the selection can be made according to the time label, and the response result selected in this way is more accurate.

Abstract

Embodiments of the present application provide a method and device for determining user intent. The method includes: after obtaining the speech recognition result, extracting a plurality of characteristic characters from the speech recognition result according to preset rules, wherein each characteristic character corresponds to each level in a preset tree structure intention library; Determine the characteristic text corresponding to the first level as the characteristic text of the current level, and determine all the intentions of the first level in the tree structure intention library as candidate intentions; match the characteristic text of the current level with each candidate intention to obtain the current intention ;Update the feature text corresponding to the next level to the feature text of the current level, update all the intents of the next level corresponding to the current intent to candidate intents, repeat the matching process, and when all the feature texts are matched, determine the current intent for user intent. Applying the solution provided by the embodiment of the present application can improve the accuracy of the determined user intention.

Description

technical field [0001] The present application relates to the technical field of intelligent information processing, and in particular to a method and device for determining user intent. Background technique [0002] At present, with the continuous development of smart technology, many smart devices have appeared, such as smart phones, robots, smart speakers, smart TVs and other devices. [0003] For the convenience of users, many smart devices are equipped with voice input and voice output functions. These smart devices can determine the user's intention according to the voice input by the user, that is, understand the semantics of the user's voice, so as to provide users with various services. [0004] In the prior art, the smart device usually determines the user intention corresponding to the user's voice according to a preset intention library, and then provides various services for the user. Specifically, the smart device performs voice recognition on the user's voic...
