Abstract

The embodiment of the invention provides a voice recognition method and device, electronic equipment and a storage medium. The voice recognition method provided by the embodiment of the invention comprises the steps of acquiring spectrum information of a first voice segment, wherein the first voice segment comprises a target voice block and an auxiliary voice block, and the auxiliary voice block is a voice block adjacent to the target voice block; and identifying the target voice block according to the spectrum information of the first voice segment and the effective interval and the weight of the auxiliary voice block. According to the speech recognition method provided by the embodiment of the invention, the time recognition precision of streaming speech recognition can be improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a voice recognition method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of deep learning, speech recognition has developed from the early hidden Markov-Gaussian mixture statistical model (hidden narkov model-mixture of gaussia, HMM-GMM)) to the latest end-to-end neural network recognition model, speech recognition The accuracy rate has made great progress. [0003] The structure of the current common end-to-end neural network recognition model is based on the connectionist temporal classification (CTC) method, including a spectrum calculation layer, a feature extraction (Encoder) layer, a fully connected (fully connected, FC) layer and Normalized exponential (Softmax) layer. Among them, the output CTC probability obtains the corresponding recognition text through the Encoder layer. Currently common...
