The invention discloses a segmentation clustering method and system for multi-person voice in a complex environment. The method comprises the following steps of: acquiring multiple continuous multi-person speaking voice segment audios according to multi-person speaking audios; and normalizing the multi-person speaking voice segment audios according to acoustic features to obtain normalized audios;acquiring multiple sections of to-be-processed audios; extracting voiceprint information characteristics of the multiple sections of to-be-processed audios; acquiring scores among all the to-be-processed audio segments by setting scoring criteria; according to the similarity scores among all the to-be-processed audio segments, acquiring category labels of a plurality of persons through a multi-stage redundant clustering algorithm; and segmenting and clustering the multi-person speaking audios according to the category labels of the plurality of persons. By using the redundant clustering method, the clustering center of a target speaker can be improved to be more dispersed, and the distinction degree is higher. And for an unclear voice segment of the target speaker in a complex environment, a better discrimination capability is realized, so that the classification error of speaker classification in a segmentation clustering task in the complex environment is reduced.
