Embodiment Construction

[0076] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0077] see figure 1 , is a flow chart of a voice control method provided by an embodiment of the present invention; the method includes:

[0078] Step 101: receiving voice information input by the user;

[0079] The background server receives the voice information input by the user, and the voice information can be: planning travel schedule, or National Day Southeast Asia, etc., that is, the user can input any voice information as required.

[0080] Step 102: converting the voice information into text;

[0081] Wherein, for the conversion method in this step, the background server may adopt an end-to-end neural network model, such as a convolutional neural network (CNN, Convolutional Neural Networks) and the like. The specific ...

Abstract

The embodiment of the invention provides a voice control method and device. The method comprises the following steps that: receiving voice information input by a user; converting the voice informationinto a text; according to the text, judging whether the intention of the user is a combined task or not; if the intention of the user is the combined task, mapping the combined task to a plurality ofsub-tasks; extracting the element information of each sub-task; according to each piece of element information and a dialogue context, determining a maximum dialogue state under a current probability; according to the dialogue state, adopting a hierarchical reinforcement learning method to decide a current optimal dialogue behavior; according to the dialogue behavior, generating a corresponding text response; and converting the text response into a text, and outputting the text. By use of the embodiment of the invention, data generated in a human-computer interaction process can be effectively utilized, cross-field complex voice input is identified and comprehended, a search space is reduced, and cross-field complex tasks can be more flexibly processed.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a voice control method and device. Background technique [0002] With the rapid development and maturity of voice technology, voice, as a new way of human-computer interaction, has become one of the possible important entrances of the Internet and the Internet of Things in the future. For example, users can send voice messages to hardware devices such as mobile phones or speakers installed with voice assistants, conduct a single-round dialogue with the system, and control the system to call specific applications to complete specified tasks. [0003] At present, the voice control technology is usually implemented in the following ways: one is to compare and match the voice information input by the user with the preset instructions in the voice information database, and if the matching is successful, the operation according to the instructions will generate corresponding results;...
