Abstract

The present disclosure relates to a speech recognition method, device, electronic device and storage medium. The method includes: extracting a corresponding original voice feature sequence from the speech data to be recognized of the current speaker; inputting the original voice feature sequence into a voice recognition model; encoding the original voice feature sequence to generate a corresponding voice feature sequence; The speech feature sequence and the trained basic feature group containing multiple speaker features are calculated to obtain the speaker feature sequence of the current speaker; according to the speaker feature sequence and the voice feature sequence of the current speaker, the target voice feature sequence is generated; The target speech feature sequence is decoded to generate a speech recognition result. By selecting multiple speaker features as the basic feature group, the speaker features of the current speaker are calculated from these basic features, so that there is no need to use a separate model to extract the speaker features of the current speaker, which simplifies the speaker features of the current speaker Feature acquisition process.

Description

technical field [0001] The present disclosure relates to the technical field of speech recognition, and in particular, to a speech recognition method, apparatus, electronic device, and storage medium. Background technique [0002] Automatic Speech Recognition (ASR) is the process of converting human speech into corresponding text through algorithms. In recent years, speech recognition technology based on deep learning has developed rapidly. The speech recognition system has been greatly improved in terms of performance and robustness. The recognition rate of the actual speech recognition system is gradually approaching the practical level. Whether it is a speech-based product or a start-up company, as well as the speech recognition technology itself is mushrooming and growing. stand up. [0003] The emerging methods in the field of speech recognition are based on end-to-end technology. In the related art, when using an end-to-end speech recognition system, a speaker featu...
