Embodiment 1

[0074] see figure 1 , the embodiment of the present invention provides a voice query method, including step S10 to step S50, specifically as follows:

[0075] S10. Receive a user's voice query request.

[0076] In the embodiment of the present invention, it can be executed by the user terminal, which directly receives the user's voice and performs voice interaction with the user; it can also be executed by the server, then the user can be referred to as the user terminal, and the user terminal receives the user's voice and transmits the voice signal Send it to the server for voice recognition and perform subsequent query operations. The user terminal includes, but is not limited to, a mobile phone, a wearable device, a vehicle-mounted device, and the like.

[0077] S20, perform voice recognition on the voice query request, and obtain the query sentence.

[0078] In the embodiment of the present invention, the voice query request is a voice signal, which can be converted by ...

Embodiment 2

[0094] see image 3 , On the basis of Embodiment 1, this embodiment provides an intent classification model and an object recognition model for intent recognition and object recognition, that is, the specific implementation process of step S30 in Embodiment 1 includes:

[0095] S31. Identify the query statement according to the intent classification model, and obtain the query intent of the query statement.

[0096] In this embodiment, the intent classification model can be trained by machine learning, that is, query sentences and intent words are associated to form training data pairs, and then a large amount of training data pairs are input into the intent classification model for training.

[0097] S32. Identify the query statement according to the query intent and the object recognition model, and obtain query object words of the query statement.

[0098] Since the query statement contains multiple words, when the object recognition model is used to identify the slot of t...

Embodiment 3

[0113] see Figure 8 , the embodiment of the present invention also provides a device for voice inquiry, including:

[0114] Voice query receiving module 10, for receiving the user's voice query request;

[0115] Query statement obtaining module 20, is used for carrying out speech recognition to described voice query request, obtains query statement;

[0116] The intent and object recognition module 30 is used to perform intent recognition and object recognition on the query sentence, and obtain the query intent and query object words of the query sentence; wherein, the query object words correspond to at least one query object;

[0117] A query object confirmation module 40, configured to determine the query object of the query statement based on the query object words; and

[0118] The query database module 50 is configured to query a retrieval database according to the query intention and the query object of the query statement, and obtain a query result.

[0119] With r...

Abstract

The invention provides a voice query method and device, a storage medium and terminal equipment. The method comprises the steps that a voice query request of a user is received; voice recognition is performed on the voice query request, and a query statement is acquired; intention recognition and object recognition are performed on the query statement to obtain a query intention and a query objectterm of the query statement, wherein the query object term corresponds to at least one query object; the query object of the query statement is determined based on the query object term; and a retrieval database is queried according to the query intention and the query object of the query statement to obtain a query result. By the adoption of the voice query method and device, the storage mediumand the terminal equipment, query accuracy can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a voice query method, device, storage medium and terminal equipment. Background technique [0002] Information query system is a system to solve information query. The query system based on search engine is currently the most popular information query system, which can make people obtain information more convenient and convenient. However, with the explosive growth of information, the types and methods of users' information needs are becoming more and more abundant. The traditional search engine query system can no longer effectively solve people's increasingly rich information needs. [0003] In the past PC Internet era, the traditional search engine query system can satisfy people's general information needs. Based on the information demand side, a PC computer that can be connected to the Internet is provided as an information acquisition device. For this information ...
