The project aims to develop a speaker recognition system that identifies a speaker's identity based on the speaker's voice. These system have been in use for around twenty years and this application would be useful in telephone-based applications, where is no way to identify a user based on fingerprint or face. Like fingerprints, a person's voice has particular unique features and by using this voiceprint, their identity can be authenticated. The main components of the system are the feature extraction, speaker modeling, and pattern mactching.
