Title:
SPEECH RECOGNITION METHOD, APPARATUS, COMPUTING DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/051564
Kind Code:
A1
Abstract:
A speech recognition method, an apparatus, a computing device and a computer non-volatile readable storage medium, which relate to the field of natural language processing. The method comprises: inputting audio data into a speech recognition model to obtain an outputted preliminary recognition result (210); determining an audio segment in audio data corresponding to a text unit in the preliminary recognition result (220); for each text unit, if the sound pressure of the audio segment corresponding to the text unit meets a predetermined condition, replacing the text unit in the preliminary recognition result with a placeholder so as to obtain an intermediate result (230); determining the degree of matching between the intermediate result and each standard text sequence in a preset standard text library (240); and on the basis of the degree of matching, selecting a target standard text sequence from among the standard text sequences in the standard text library as a final recognition result (250). The described method reduces the possibility of speech recognition being inaccurate due to the existence of a text unit for which the sound pressure of a corresponding audio segment does not meet a certain requirement, thereby improving the accuracy of speech recognition.
