Title:
SPEECH RECOGNITION RESULT EVALUATION METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/095353
Kind Code:
A1
Abstract:
A speech recognition result evaluation method, apparatus and device, and a storage medium, which relate to the field of artificial intelligence, and are used for improving the evaluation efficiency of the accuracy of evaluating conversion from initial speech to initial text. The evaluation method comprises: converting initial speech in a video review item on the basis of a speech recognition function, so as to obtain initial text (101); performing space character deletion pre-processing, sorting pre-processing and punctuation character deletion pre-processing on the initial text, so as to obtain text to be subjected to detection (102); acquiring a word sequence to be subjected to detection in the text to be subjected to detection, and proofreading and marking, according to a pre-set standard word sequence, the word sequence to be subjected to detection, so as to obtain proofread text (103); calculating a character recognition error rate of the proofread text by using a pre-set calculation formula (104); and selecting a pre-set comparison result by comparing the character recognition error rate and a standard error rate, and determining a conversion evaluation result of speech conversion text (105). The present invention further relates to blockchain technology, and the initial text can be stored in a blockchain.
