Abstract: A speech recognition method includes: performing phoneme recognition on a speech signal to obtain a phoneme recognition result corresponding to a speech frame in the speech signal, the phoneme recognition result indicating a probability distribution of the corresponding speech frame in a phoneme space, and the phoneme space comprising a plurality of phonemes and a blank output; performing suppression adjustment on a probability of the blank output in the phoneme recognition result corresponding to the speech frame, to reduce a ratio of the probability of the blank output to a probability of a phoneme in the phoneme recognition result; and inputting the adjusted phoneme recognition result corresponding to the speech frame into a decoding map to obtain a recognition text sequence corresponding to the speech signal, the decoding map comprising a mapping relationship between characters and phonemes.
