VOICE KEYWORD IDENTIFICATION METHOD, APPARATUS AND DEVICE AND COMPUTER READABLE STORAGE MEDIUM

摘要

A voice keyword identification method, apparatus and device, and a computer readable storage medium. The voice keyword identification method comprises: receiving an input voice signal (101); extracting audio features in the voice signal (102); calculating, according to the audio features, the probabilities of keywords to an acoustics model, a pronunciation dictionary and a language model by utilizing the acoustics model, the pronunciation dictionary and the language model; determining whether a probability is greater than a threshold; if a probability is greater than the threshold, counting the number of the keywords corresponding to the probability; and if the number of the keywords corresponding to the probability is one, using the keyword corresponding to the probability as a keyword identification result. After the probabilities of possible keywords are calculated, a keyword corresponding to the probability greater than the threshold is used as the keyword identification result, thus improving keyword identification rate.
