An influx in post-9/11 venture investment in security technologies has brought about the current quantum leap in voice biometrics. Improved next-generation voice biometrics are a user-friendly method of authentication that provide higher levels of authentication/verification and keep costs low by increasing process automation. New voice solutions are performing far beyond current market offerings, and newer technologies can adapt to voiceprint changes, support input over landline, VoIP, and have even overcome cellular phone distortion.

Data security has become an important applications space for biometrics, and new regulations are going into effect all over the world that demand three levels of identification and verification (something the person knows, something the person has, and something the person is) in all transactions done over networks. Voice is the only truly reliable biometric, and it is the least invasive and most readily available. This white paper describes how high rates of accuracy coupled with ease-of-use will, in the coming years, make voice the biometric technology of choice for identification and authentication in an ever-expanding range of both stand-alone and multi-biometric applications.
