Abstract

The invention relates to a voice recognition method and device, electronic equipment and a storage medium. The voice recognition method comprises the following steps: acquiring an original voice signal; performing noise reduction on the original voice signal to obtain an enhanced voice signal; respectively extracting voice features of the original voice signal to obtain a first voice feature, andextracting voice features of the enhanced voice signal to obtain a second voice feature; jointly processing the first voice feature and the second voice feature by using a pre-trained acoustic model to obtain a combined state sequence; and decoding the combined state sequence to obtain a voice recognition result. The original voice signal and the voice signal after noise reduction are processed together, so that the accuracy of voice recognition is improved.

Description

technical field [0001] The present disclosure relates to the technical field of voice recognition, and in particular, to a voice recognition method and device, electronic equipment, and a storage medium. Background technique [0002] With the continuous development of artificial intelligence, more and more smart devices and fields have begun to apply speech recognition technology for human-computer interaction. [0003] In related technologies, in order to achieve more robust speech recognition, usually before speech recognition, the speech is denoised first, and then the denoised speech is sent to a recognition system for recognition. Alternatively, by optimizing the acoustic model in the recognition system, the recognition effect of the speech recognition system on speech containing noise is improved. [0004] Although these two methods can improve the recognition effect of noise-containing speech to a certain extent, in the first method, noise reduction through the speec...
