Shedding some light on Voice Authentication

Biometric authentication technology and development has grown over the last 6 years from being something we have seen on Science fiction television shows into a reality where w e can now purchase the systems and implement them both in our business and private lives. In this paper I will attempt to explain, in non-technical language, the technologies behind one particular type of biometric authentication, voice authentication. I will look at the human voice, how this is captured by technology, and how this can then be used to verify that the person is who they claim to be.
