Technical Bulletins - Authentication 101

Biometrics - Voice
Voice verification technology verifies a person's identity on the basis of voice characteristics. These unique features consist of cadence, pitch, tone, harmonics, and shape of larynx. Biometric voice verification technology balances the need to tighten security and reduce costs with the inherent convenience of the human voice. Voice verification technology solves countless security problems that require accurate user identity verification, by providing a powerful, non-intrusive solution to protect both proprietary and confidential information. Many biometric technologies are considered intrusive, and therefore, inconvenient, because they require the user to subject a part of their body to technical scrutiny. Voice recognition has difficulties handling environmental factors such as noise, and performance can be affected by colds or laryngitis, but it offers a quick and convenient technology for integration into telecommunication-based verification.
