Abstract

A speech recognition error correction method and device, and a readable storage medium are provided. The method includes: acquiring to-be-recognized speech data and a first recognition result of the speech data, re-recognizing the speech data with reference to context information in the first recognition result to obtain a second recognition result, and determining a final recognition result based on the second recognition result. In the method, the speech data is re-recognized with reference to context information in the first recognition result, which fully considers context information in the recognition result and the application scenario of the speech data. If any error occurs in the first recognition result, the first recognition result is corrected based on the second recognition. Therefore, the accuracy of speech recognition can be improved.
