Embodiment 1

[0055] see figure 2 , the embodiment of the present invention provides a speech recognition method, the method comprising:

[0056] 101: Recognize the received voice information as character information;

[0057] 102: Determine whether there is digital information corresponding to the character information in the preset grammar rules;

[0058] 103: Obtain a recognition result according to the digital information when it is determined that there is digital information corresponding to the character information in the preset grammatical rules.

[0059] The method provided by the embodiment of the present invention recognizes voice information as character information, and judges whether there is digital information corresponding to the character information according to the preset grammatical rules. The character information is determined as the recognition result, and the character information without corresponding digital information is excluded to realize the filtering proce...

Embodiment 2

[0061] see image 3 , the embodiment of the present invention provides a speech recognition method, the method comprising:

[0062] 201: Receive voice information;

[0063] Wherein, the execution subject of this embodiment is the voice recognition device, which can be triggered by the user to receive the voice information, or the voice recognition device can actively receive the voice information from the user. For example, a receiving window or a receiving button can be set on the speech recognition device, and the user triggers the receiving window or the receiving button. After the speech recognition device receives the trigger operation of the user, it starts to receive the voice information sent by the user; The recognition module receives the sound when it recognizes that there is a sound, so as to further recognize the sound.

[0064] 202: Recognize the received voice information as character information;

[0065] Specifically, there are many ways to recognize the re...

Embodiment 3

[0098] see Figure 4 , an embodiment of the present invention provides a speech recognition device, the device comprising:

[0099] A recognition module 301, configured to recognize the received voice information as character information;

[0100] The first judging module 302 is configured to judge whether there is digital information corresponding to the character information in the preset grammar rules;

[0101] The processing module 303 is configured to obtain a recognition result according to the digital information when it is determined that the preset grammar rule has digital information corresponding to the character information.

[0102] Among them, see Figure 5 , the device also includes a second judging module 304, including:

[0103] A judging unit 3041, configured to judge whether the character information is preset command character information;

[0104]The execution unit 3042 is configured to perform an operation of judging whether there is digital informati...

Abstract

The invention discloses a voice recognition method and a voice recognition device, and belongs to the field of voice recognition. The method comprises the following steps of recognizing the received voice information as character information; judging whether digital information corresponding to the character information exists in preset grammar rules or not; and obtaining recognition result according to the digital information when judging that the digital information corresponding to the character information exists in the preset grammar rules. The device comprises a recognition module, a first judgment module and a processing module. The process of recognizing natural language of human being by a machine is realized, the training work of flight command can be carried out by a flight commander, and a computer-generated intelligent airplane is controlled according to commands recognized by the machine; and the voice recognition method can be suitable for different speakers, so that voice recognition can be finished by different people through the voice recognition method.

Description

technical field [0001] The invention relates to the field of voice recognition, in particular to a voice recognition method and device. Background technique [0002] With the continuous development of computer and information technology, voice interaction has become a necessary means of human-computer interaction. As one of the important technologies of voice interaction, after nearly half a century of development, voice recognition technology has become increasingly mature and widely used. Speech recognition technology is a technology for machines to convert speech signals into corresponding text or commands through the process of recognition and understanding. [0003] The existing speech recognition technology is generally a text recognition technology, which uses a common dictionary for matching. The common dictionary has a lot of content and covers a large vocabulary, and is suitable for random dictation without specific goals. [0004] In the process of realizing the...
