Embodiment 1

[0056] figure 1 It is a flow chart of a speech recognition method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of improving the speech recognition rate. The method can be executed by a speech recognition device, which can use software and / or hardware The device can be implemented in a terminal, such as a typical mobile phone, a tablet computer, and the like. Such as figure 1 As shown, the method specifically includes the following steps:

[0057] S110. When the utterance event is triggered, receive the voice signal and the image signal including lips sent by the microphone and collected by the user during the utterance event;

[0058] In a specific embodiment of the present invention, the sounding event may represent a sound generated during learning activities or entertainment activities using the functions of the terminal, such as reading a text or singing a song. And usually in the process of carrying out the above act...

Embodiment 2

[0078] figure 2 It is a flow chart of a speech recognition method provided by Embodiment 2 of the present invention. This embodiment is applicable to the situation of improving the speech recognition rate. The method can be executed by a speech recognition device, which can use software and / or hardware The device can be implemented in a server, such as a typical server.

Abstract

The invention discloses a voice recognition method, device and apparatus and a storage medium. The method includes: when a sounding event is triggered, receiving a voice signal sent by a microphone and acquired by a user during the execution of the sounding event and an image signal including a lip; performing feature extraction on the voice signal to generate a voice feature signal, and performing feature extraction on the image signal including the lip to generate a lip-language feature signal; sending the voice feature signal and the lip-language feature signal to a server to instruct the server to match the voice feature signal with a preset voice signal to generate a voice recognition result and to match the lip-language feature signal with a preset lip-language signal to generate a lip-language recognition result; if the similarity between the voice recognition result and the lip-language recognition result is greater than or equal to a similarity threshold, generating a recognition feedback result according to the voice recognition result and sending the recognition feedback result to a terminal. The embodiment of the invention achieves improved voice recognition rate.

Description

technical field [0001] Embodiments of the present invention relate to speech recognition technology, and in particular to a speech recognition method, device, equipment and storage medium. Background technique [0002] With the advent of the electronic information age, mobile devices are becoming more and more popular, mobile terminals and external devices of mobile terminals, such as children's tablet computers and microphones. In addition, the functions that can be realized by the above-mentioned devices are becoming more and more abundant. For example, a microphone can be connected to a mobile terminal to perform language learning or song singing according to the content displayed on the mobile terminal. In this process, the microphone is required to record the user's voice in real time. Then upload the sound to the mobile terminal, perform corresponding speech recognition in the mobile terminal, and then obtain the speech recognition result, and then give the evaluation ...
