Identification Techniques Using Voice Recognition

Voice biometric devices are safe and convenient

Voice recognition is a useful and interesting use of biometrics, and it is especially attractive due to the convenience that it provides. It is also unique among biometric identifiers in that it can ensure a person's identity without requiring them to be physically present. Voice biometric devices are already in use for a number of different purposes, and they are providing excellent results.

Biometric technology involves the measuring of two different types of biometric identifiers: what are called the behavioral components and physical components. In the field of voice recognition, the behavioral component could be described as nuances that are unique to a particular individual that are not physiological in nature, such as an accent. There are broad swatches of accents that are regional or adapted within a particular sub-culture, but even within these wider behavioral components each person speaks with his or her own interpretation of that accent in a way that is unique to them.

The physical component of voice recognition involves the vocal tract. That exact texture and pitch of a person's voice is as unique as a fingerprint, and no two individuals share the exact same vocal tract. This is what makes voice biometric devices accurate enough to be used for security and sensitive access purposes, and when you combine both the behavioral and physical components, voice recognition becomes just as reliable as any of the other biometric identifiers, like iris, facial, fingerprint and hand scanning applications.

An interesting use of the voice biometric devices is the way that they are applied by probation and parole bureaus. Their charges are routinely required to contact them by phone and check in at regular intervals that are determined by the court. This system has always been less than perfect, however, because an individual could have someone else call in on his or her behalf imitating their voice. Biometric voice recognition eliminates this possibility, and it is widely used in his context around the world.

Another application of this form of biometric identification is the biometric lock. There are locks available now that open when they recognize your voice. So with voice biometric devices it's just like it was in those books that we read as children where people opened doors by simply saying "Open Sesame". A voice recognition biometric lock is useful and convenient, but let's face it, it is a lot of fun to be able to open your door with a voice command. Plus, you never have to worry about getting locked out of your house...unless of course you come down with a case of laryngitis!

Biometric identifiers are becoming more and more ubiquitous every day, and before long we will be able to access our various accounts over the phone without using a password. Imagine calling to check on your credit card balance and being instantly authenticated by simply stating your name. That is the direction that biometric technology is taking us, and it will be very interesting to see how it impacts our lives over the next few years.
