Title:
SPEECH RECOGNITION MODEL TRAINING METHOD AND APPARATUS, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/011902
Kind Code:
A1
Abstract:
A speech recognition model training method and apparatus, a storage medium, and an electronic device. The speech recognition model training method comprises: constructing an initial speech recognition model (S101); fixing a second initial parameter, and calculating a contrastive learning loss function on the basis of an unlabeled dataset to adjust a first initial parameter to a first intermediate parameter (S102); fixing the first intermediate parameter, and calculating a first joint loss function on the basis of a labeled dataset to adjust the second initial parameter to a second intermediate parameter (S103); and calculating a second joint loss function on the basis of the labeled dataset, and training a first network and a second network according to the second joint loss function to adjust the first intermediate parameter and the second intermediate parameter to obtain a target speech recognition model (S104). The speech recognition model training method provided by the present disclosure can solve the problem of low recognition performance of a speech recognition model when labeled data is insufficient.
