Abstract

The present invention provides an end-to-end speech recognition method, device and electronic device. The method includes: acquiring speech audio data to be recognized; Speech recognition result; wherein, the sparse word speech recognition model is a model obtained by pre-training based on sparse word data samples and excitation parameters, and the key sparse words are sparse words with substitution errors. The designed excitation parameters are combined with sparse word data samples to train a sparse word speech recognition model with accurate recognition, so as to apply the model to the process of speech recognition, so as to improve the recognition effect of sparse words on the basis of ensuring the recognition effect of daily words. Recognition accuracy of specialized vocabulary terms.
