Abstract

The invention provides a voice recognition and encoding and decoding method and a device thereof, electronic equipment and a storage medium, and relates to the field of intelligent voice, deep learning, natural language processing and other artificial intelligence, and the voice recognition method can comprise the steps: obtaining the audio features of a to-be-recognized voice; encoding the obtained audio features to obtain encoded features; performing truncation processing on the obtained coding features to obtain N continuous feature fragments, wherein N is a positive integer greater than one; and for any feature segment, obtaining corresponding historical feature abstract information, encoding the feature segment in combination with the historical feature abstract information, and decoding an encoding result to obtain an identification result corresponding to the feature segment, wherein the historical feature abstract information is information obtained by performing feature abstraction on the identified historical feature segment. By applying the scheme of the invention, the accuracy of an identification result and the identification efficiency can be improved.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence technology, and in particular to speech recognition and codec methods, devices, electronic equipment, and storage media in the fields of intelligent speech, deep learning, and natural language processing. Background technique [0002] Automatic speech recognition refers to the process of automatically converting the input speech into corresponding text by computer. With the in-depth research of deep learning technology in the field of speech recognition, especially the proposal of end-to-end speech recognition technology, the performance of speech recognition system has been improved. a great improvement. Moreover, with the continuous popularization of various smart devices, large-scale vocabulary speech recognition products have been widely used in fields such as smart customer service, car navigation, and smart speakers. [0003] In speech recognition with a large vocabulary, the...
