VoiceID is a speaker recognition/identification system written in Python, based on the LIUM Speaker Diarization http://lium3.univ-lemans.fr/diarization/doku.php framework.

VoiceID can process video or audio files to identify in which slices of time there is a person speaking (diarization); then it examines all those segments to identify who is speaking. To do so uses a voice models database.
