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.
