Abstract

The application discloses a speech recognition method, device, electronic equipment and computer storage medium. The specific implementation plan includes: recognizing the target speech to obtain the recognition text of the target speech; based on the recognition text and the target speech, determining the multi-dimensional features of each word in the recognition text; The feature of the dimension determines the detection result of each character in the recognition text; the first recognition text is generated based on the detection result of each character, wherein the first recognition text includes each character in the recognition text and its corresponding mark.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular to a speech recognition method, device, electronic equipment and computer storage medium. Background technique [0002] With the improvement of the technical level of Automatic Speech Recognition (ASR), the research on the processing of the transcribed text output from the ASR system has also received extensive attention. Taking the field of education as an example, the analysis of teaching reports such as teachers' lectures and students' lectures, and learning status reports require converting the voices of teachers and students during the class into text for subsequent natural language processing. When there are errors in the recognized text, it will have a great impact on subsequent natural language processing tasks. Therefore, text error correction of speech recognition results is an important post-processing technology for speech recognition. Speech rec...
