Problems solved by technology

[0005] In these currently disclosed technologies, there is such a problem that when other people issue corresponding commands, since the wake-up system itself does not have the ability to identify the user's identity, the user's own system will also be woken up, which greatly increases the number of users. Risks when using

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Since everyone's voice is unique, it is uniquely advantageous to confirm the user's identity through voiceprint recognition. For example, voiceprint recognition to confirm the user's identity can truly realize the irreplaceability of the waker. Even if someone else deliberately wakes up the system, the system can also judge that it is not the user himself and refuse to be woken up.

[0025] Voiceprint recognition is also called speaker recognition. Voiceprint recognition includes two types: Text-Dependent and Text-Independent. The text-related voiceprint recognition system requires users to pronounce according to the specified content. The voiceprint model of each person is accurately established one by one, and the recognition must also be pronounced acco...

Abstract

Embodiments of the present invention provide a voice command recognition method and device. The method includes: obtaining a generalized background model, and obtaining a user's voiceprint model based on the user's registered voice; receiving the voice, extracting the voiceprint features of the voice, and based on the voiceprint features of the voice, the generalized background model and the The user voiceprint model determines whether the voice is from the user; when it is determined that the voice is from the user, identifying command words in the voice. The embodiment of the present invention can determine whether the voice originates from the registered user based on the voiceprint model of the registered user, thereby improving security.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Automatic Speech Recognition (ASR, Automatic Speech Recognition), and more specifically, to a voice command recognition method and device. Background technique [0002] Automatic speech recognition technology is a technology that converts the lexical content in human speech into computer-readable input characters. Speech recognition has a complex processing flow, mainly including model training, decoding network construction, and decoding. [0003] Voice command recognition technology is a specific application of automatic voice recognition technology. Its main function is that the user does not need to use keyboard, mouse, touch screen and other input devices, as long as the voice of the command word is spoken, the voice command recognition system will automatically recognize the voice. The corresponding character string, if the character string is the character string correspondin...
