Abstract

The embodiment of the invention provides a speech recognition method, a speech recognition device and electronic equipment, and belongs to the technical field of computers. The speech recognition method comprises the steps of obtaining the feature information of a current to-be-recognized speech signal; processing the feature information through an encoder to obtain M speech feature vectors, M being a positive integer greater than or equal to 1; processing the M speech feature vectors through a CTC model, obtaining N pronunciation units in the M speech feature vectors, wherein N is a positiveinteger smaller than or equal to M and larger than or equal to 1; processing the M speech feature vectors and the N pronunciation units through an attention model, generating Y context feature vectors, wherein Y is a positive integer larger than or equal to N; and processing the Y context feature vectors through a decoder network to obtain a recognition result of the current to-be-recognized speech signal. According to the technical scheme of the embodiment of the invention, the accuracy of speech recognition can be improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a voice recognition method, device and electronic equipment. Background technique [0002] At present, mainstream speech recognition technologies are divided into several parts: acoustic model and speech model. For the training of the traditional acoustic model of speech recognition, for each frame of data, it is necessary to know the corresponding label (label) in order to carry out effective training, that is, before training the data, preprocessing of speech alignment is required. The process of voice alignment itself requires repeated iterations to ensure the accuracy of the alignment, which itself is a relatively time-consuming and resource-consuming task. [0003] In the field of speech recognition, how to improve the accuracy of speech recognition is a technical problem to be solved urgently. [0004] It should be noted that the information disclosed in the a...
