Abstract:
Provided are a corpus screening method and apparatus for speech recognition training, and a computer device and a computer-readable storage medium. The embodiments of the present application belong to the technical field of speech recognition. The method comprises: labeling corpora according to timestamps to obtain a first corpus set; training, by means of the first corpus set, a speech recognition model to obtain a first speech recognition model; decoding, by means of the first speech recognition model, each corpus segment in the first corpus set to obtain a first word sequence corresponding to each corpus segment; comparing each first word sequence with a standard word sequence corresponding to the first word sequence to calculate a first word recognition rate for each corpus segment; determining whether the first word recognition rate for each corpus segment meets a preset first word recognition rate condition; and storing the corpus segments corresponding to the first word recognition rates that meet the preset first word recognition rate condition, so as to form a screened second corpus set.
