Speaker verification
Biometric Technology Today · 2001
Speaker verification is the most highly commercialized form of a group of technologies that are called speaker recognition or voice biometrics. Other voice-biometric technologies include speaker identification, voice stress analysis and lie detection. Like most other biometric-based security technologies, speaker verification has been experiencing increased market and investor interest. Despite the dot.com crash, 2001 has been a very good year for vendors, with the number of pilots and actual deployments increasing.
