Abstract
This patent disclosure relates to a voice technology and discloses a voice recognition method and electronic device. In some embodiments of this disclosure, soft clustering calculation is performed in advance according to N gausses obtained by model training, to obtain M soft clustering gausses; when voice recognition is performed, voice is converted to obtain an eigenvector, and top L soft clustering gausses with highest scores are calculated according to the eigenvector, wherein the L is less than the M; and member gausses among the L soft clustering gausses are used as gausses that need to participate in calculation in an acoustic model in a voice recognition process to calculate likelihood of the acoustic model.
