Abstract

The invention discloses a voice recognition method, device and system, and a computer readable storage medium. The method comprises the steps: carrying out the voice recognition of to-be-recognized voice data, and obtaining each first candidate result of the to-be-recognized voice data; obtaining feature data corresponding to each first candidate result, and inputting each piece of feature data into a pre-trained sorting model to obtain the sorting result of each first candidate result; and selecting a target candidate result from the first candidate results as the voice recognition result ofthe to-be-recognized voice data according to the sorting result. Compared with a linear score combination mode set according to human experience, a more accurate sorting result can be obtained, so that a more accurate voice recognition result can be obtained.

Description

technical field [0001] The present invention relates to the technical field of voice data processing, in particular to a voice recognition method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of speech data processing technology, speech recognition system has been widely used in various fields. In the speech recognition system, N-best Hypotheses Rescoring is an important part, which has a crucial impact on the speech recognition effect. N-candidates are N candidate results obtained from speech data recognition, and N-candidate re-scoring is to re-score and sort the N candidate results. The current N-candidate re-scoring method is to first use the voice model (Acoustic Model) and language model (Language Model) to evaluate and score each candidate, and then combine the voice model score and language model score to give the N-candidate The final ranking result of , and the candidate ranked first is taken as the fi...
