Abstract

The present invention proposes a speech recognition method and device. The speech recognition method includes: acquiring the features of the speech signal to be recognized; performing path search in the search space generated by the composition according to the features, and outputting a decoding result; according to the decoding result Judging whether recognition rejection is required; if recognition rejection is required, it is determined that the speech recognition result is recognition rejection, and if recognition rejection is not required, the speech recognition result is obtained according to the decoding result. This method has a very good recognition rejection effect.

Description

technical field [0001] The present invention relates to the technical field of voice, in particular to a voice recognition method and device. Background technique [0002] Voice technology can provide people with a very convenient user experience, especially on mobile and wearable devices. At present, speech recognition technology mainly uses online services for recognition, but if there is no network or the network is unstable, the online service cannot meet the demand, and the traditional offline speech recognition system does not have the effect of rejection. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, an object of the present invention is to propose a speech recognition method, which has a good recognition rejection effect. [0005] Another object of the present invention is to provide a speech recognition device. [0006] In order to achieve...
