Voice biometric also known as voice verification system can be used to confirm a person’s claimed identity or sometimes to identify a particular person. Fake identities have continued to rise and organisations are longing to help customers securely and help them access information as swiftly as possible. Voice biometrics has developed as a way to resolve these challenges and protect customer data. With the help of a password or a PIN voice biometrics can be used alone to cater a suitable technique of verifying customer identities via “voiceprints”.
The voice biometric authentication has started expanding in the past few years. According to a study made by Opus Research, there will be more than a billion voiceprints by the end of 2020. Customers rely on biometrics authentication and therefore organisations are using voice verification system to improve security while protecting the air of contentment for the customers. A lot of BPO companies are using voice biometrics to provide a secured gateway to the customers.
A voice biometric system includes various features for multiple customer deployment. They are
- Transferring data through wire
- Customer service verification
- Employee management check-in
For instance, telephone banking needs a secured gateway because most of th financial details and information are stored within the premises of a bank. The voice verification acts as gatekeeper in order to protect secured system. These systems function with the customers’ information or knowledge and usually need their assistance to access crucial information. This also can be implemented to identify talkers in a discussion without the user’s knowledge. There are various technologies that are used by the voice prints to identify a sound such as frequency estimation, pattern matching algorithms, neural network, matrix representation, vector quantization and decision trees.
How does voice biometric system functions?
Computers are smart and therefore, capable of converting speech into on-screen text or commands. But the question is how does it actually work? Vibrations are produced in the sir when words are spoken and these vibrations are converted into digital data to be evaluated by the computer. Everything is measured digitally with the help of waves at intervals and the voice software then filters the sound by eliminating background noises.
This system is a crucial application for leading BPO companies to protect the sensitive information of computer systems. The standard software can determine what the person is saying but the programs that are used for security purposes are used generally for speaker identification or verification.
