The invention discloses a voice recognition method and device for sensitive words. Wherein, the speech recognition method of sensitive words includes: obtaining the audio to be tested; utilizing the pre-established sensitive word training model to mark the audio segments in the audio to be tested, and marking the audio segments containing the target sensitive words in the audio to be tested as the first A preset identification, wherein, the sensitive word training model is a model obtained by training according to the audio data marked with the first preset identification and containing the target sensitive word, and the sensitive word training model is used to detect the voice of the target sensitive word; and from An audio segment with a first preset identifier is extracted from the marked audio to be tested as the audio of the target sensitive word. Through the present invention, the problem of low recognition accuracy of speech-sensitive words in the prior art is solved, and the effect of improving the recognition accuracy of speech-sensitive words is achieved.
Description
technical field [0001] The invention relates to the field of voice detection, in particular to a voice recognition method and device for sensitive words. Background technique [0002] At present, the speech recognition technology of sensitive words is mainly based on the established speech sensitive word corpus, and the sensitive words are identified by matching analysis. The disadvantage is that the speech sensitive word corpus needs to be established in advance, and multiple corpora need to be established for multilingualism; In the process of analyzing voice-sensitive words, it is necessary to translate them into text first and then match sensitive words according to the text corpus to locate the phonetic position of sensitive words. The recognition accuracy of such voice-sensitive words is low. [0003] Aiming at the problem of low accuracy of voice-sensitive word recognition in the prior art, no effective solution has been proposed yet. Contents of the invention [0...
