Abstract
A speech recognition method. The method includes: performing speech activity detection on speech data to obtain multiple speech segments; determining, for each of the speech segments, a number of speakers involved in the each of the speech segments; for each of at least one of the speech segments with the determined number greater than 1: performing speech separation on the each of at least one of the speech segments to obtain multiple audio segments; performing speech recognition on each of the audio segments to obtain respective first speech recognition results for the audio segments; performing feature extraction on each of the audio segments to obtain respective voiceprint feature vectors; and performing clustering on the audio segments with respect to the speakers to obtain a clustering result; and obtaining a second speech recognition result for the speech data based on the clustering result and the respective first speech recognition results.
