Voice Recognition Biometrics Systems!

Voice recognition biometrics has many uses and this technology is quickly expanding.

Biometrics voice recognition security has become popular.

Since this technology offers high level security systems that require speech based biometric speaker verification and biometric identification.

Today these systems are used on site for business and home security, implemented into customer call centers and even used online to establish identity and verification.

How Does Voice Recognition Biometrics Work?

A voice recognition biometrics system works by taking a profile of a person’s voice, digitizing it and then developing a voice template or voiceprint.

Some devices work by paying attention to vocal sounds and how words are said. Other systems simply focus on unique speech sounds and patterns. The systems parameters identify a biometric voiceprint, then storing the print in the systems biometric database, much as fingerprints are stored in a fingerprint biometrics system.

Of course, a high quality voice sample is essential for any voice recognition security system. To get a good sample, individuals often have to receive a pass phrase or piece of text that may need to be repeated a few times.

While many devices still require fixed pass phrases, technology has advanced so some systems don’t need specific pass phrases. They can recognize speech similarities, no matter what phrases are given as a voice sample.

Potential Problems

With biometric voice recognition, anyone considering implementation of this technology must consider a few potential problems.

First, physical ailments that affect speech can be problematic when individuals are submitting a voice sample. For example, if someone has a bad cold or they are speaking in a very exciting voice, these factors can affect the results.

Another potential problem is biometric input device quality and background noise. If a lot of noise is going on in the background, it may be difficult for the system to provide accurate results. Also, low quality input devices may not be able to provide high quality voice samples, which can lead to accuracy problems within this technology.

When these biometric systems are used over the phone, there is also a possibility that someone could make a recording of an individual to gain access. However, more sophisticated biometrics voice recognition security devices are focusing on this problem and often use “liveness” testing to ensure recordings are not used.

Benefits of Voice Recognition Biometrics

Although a speech recognition biometrics system can offer some potential challenges, this technology does offer a variety of excellent benefits as well.

Consumer devices that are used for voice recognition security have the benefit of being inexpensive, especially when compared to other types of biometrics technology. Systems are very easy to implement, since setting up a system includes a minimal amount of new equipment.

In fact, many systems merely require the purchase of an input device and biometrics software that can easily be installed into a computer system. Not only is speaker recognition a reasonably priced biometric security option, but it is also user friendly.

It’s easily to collect voice samples, even over the phone. Many individuals today feel uncomfortable with biometric systems that are more invasive, such as retinal scanners and hand print scanners. Individuals merely have to speak into an input device with voice recognition systems, making them a popular choice among users today.

Biometrics In Banking Real World Implementation

Already, voice recognition is being implemented around the world in a variety of ways. Many banks are beginning to use these speech recognition systems to verify users that call into phone banking systems.

This offers an extra layer of security to consumers that prefer to bank by phone. Other financial based call centers are beginning to implement these systems for better security as well. Companies that are looking for better security are experimenting with voice recognition security systems as well.

These devices are fairly cheap and easy to implement and most company employees prefer using speech recognition to other biometric technologies. This technology is even showing that it has a place in home security systems.

Overall, it’s easy to see that voice recognition biometrics is here to stay and poised to grow even more in the next few years. With unique advantages, such as user-friendliness and low cost, it has many different biometric applications, making it a technology worthy of consideration.
