Abstract

The embodiments of the invention provide a corpus screening method and device for speech recognition training, computer equipment and a computer readable storage medium, and belong to the technical field of speech recognition. A first corpus set is obtained by labeling corpora according to timestamps, the first corpus set is used for training a speech recognition model to obtain a first speech recognition model, the first speech recognition model is used for decoding each corpus segment in the first corpus set to obtain a first word sequence corresponding to each corpus segment, a first word recognition rate of each corpus segment is calculated by comparing each first word sequence with a standard word sequence corresponding to the first word sequence, whether the corresponding first word recognition rate of each corpus segment meets the preparatory condition of the first word recognition rate or not is judged, corpus segments corresponding to the corresponding first word recognition rates which meet the preparatory condition of the first word recognition rates are stored to form a screened second corpus set, and training corpora with the high accuracy can be effectively screened out.

Description

technical field [0001] The present application relates to the technical field of speech recognition, in particular to a corpus screening method, device, computer equipment and computer-readable storage medium for speech recognition training. Background technique [0002] A good speech recognition model is inseparable from tagged corpus with good quality tags, but the corpus collected and collected through various channels usually cannot guarantee the accuracy of its tags, so the collected corpus is used directly for speech recognition model training, where the tagged An incorrect corpus is not only useless for training, but also reduces the accuracy of the speech recognition model. Contents of the invention [0003] The embodiment of the present application provides a corpus screening method, device, computer equipment, and computer-readable storage medium for speech recognition training, which can solve the problem of inaccurate speech recognition models caused by inaccur...
