ABSTRACT
Among various user authentication techniques, speaker authentication concerns with authenticating a person’s identity via voice. There are two approaches to speaker authentication: speaker verification (SV) and verbal information verification (VIV). The SV approach attempts to verify a speaker’s identity based on his/her voice characteristics while the VIV approach verifies a speaker’s identity through verification of the content of his/her utterance(s). In this chapter, we first introduce the related pattern recognition and verification techniques, and then present an SV system, a VIV system, and a combined system with both SV and VIV for convenience and performance improvement. These systems are ready for real-world applications.
