Abstract

An identity consistency check method and apparatus based on a speech spectrum and phoneme retrieval. The method comprises: acquiring a speech spectrum corresponding to a sample audio file (101); acquiring a phonetic feature parameter of the sample audio file (102); constructing a phoneme recognition model, and inputting the phonetic feature parameter into the phoneme recognition model to perform phoneme retrieval, to obtain a qualifying phoneme (103); and labeling the qualifying phoneme on the speech spectrum, and performing a consistency check on a vowel or a vowel combination having the same label, to judge whether the verification of an identity to be recognized corresponding to the sample audio file is passed (104). The technical problem of phoneme search and query in actual voice print verification is solved, and a phoneme is displayed in a visualized manner, improving the recognition efficiency of case handling staff.

Description

technical field [0001] The invention relates to the field of speech recognition, in particular to a method and device for checking identity identity based on spectrogram and phoneme retrieval. Background technique [0002] After adulthood, the human voice can remain relatively stable for a long time. Experiments have proved that no matter whether the speaker deliberately imitates the voice and tone of others, or whispers softly, even if the imitation is vivid, the voiceprint is always the same. Based on these two characteristics of the voiceprint, investigators can compare the acquired voiceprint of the criminal with the voiceprint of the suspect through voiceprint identification technology, quickly identify the criminal, and provide reliable evidence for the investigation and solution of the case. [0003] The existing voiceprint identity verification method is mainly to manually search for similar vowels one by one in the corresponding display spectrogram of the recorded ...
