Voice Recognition Technology as the Future for Authentication

The use of voice recognition technology has risen with the development of biometrics. Voice recognition technology is used in various industries such as healthcare, finance, education, and digital security, among others. The technology helps identify and authenticate the person by tracking the cadence and accent of the speaker as well as the size and form of their larynx, nasal passages, and vocal tract.


Voice Recognition for Authentication


How is voice recognition technology used in authentication? First, the system is fed with voice recordings and other useful information about the speaker. It then notes their voice print, speech, and breathing pattern. This information is then analyzed, encoded, and saved in the Active Directory of the speaker's verification profile along with other identification details. This enables the user to use their voice as authentication and prevent access by unauthorized parties.


Given that it doesn't require hardware integration, unlike other technologies like fingerprint matching or retinal scan, voice authentication offers a versatile and affordable method of biometric authentication. Businesses use speech recognition to improve security and give consumers a variety of verification choices. Some of the industries where voice-based authentication is utilized include:


Entertainment: Voice recognition technology can be employed in the entertainment industry to stream movies, open and close screens, and switch between radio or TV stations. Additionally, it can aid in tailoring the client experience. For example, voice analysis can be used to customize streaming services like Netflix so that users can get content that is appropriate for their age.


Healthcare: Health professionals can utilize voice biometrics to dictate and record patient health conditions directly into the system and securely retrieve patient personal history in a sector where data security is of the utmost importance. Patients who need to exchange medical records between different doctors can benefit greatly from this. By automating payment collection, the system can also significantly lower fraud for payers and providers and increase patient satisfaction by providing an extra payment method.


Banking: Voice authentication is available for use with bank lockers. Banks can employ voice recognition technology to enhance the security and sophistication of payment methods. Voice biometrics have been adopted by credit card firms and banks like Citibank and ANZ to proactively identify fraudsters and authenticate callers at their call centers in response to the growth in fraud.


Education: Schools can employ voice recognition to allow visually impaired pupils take online tests via voice verification.


Independent software vendors, ISVs: Voice authentication can facilitate firm sign-in processes like those ran on the Active Directory, facilitating uniform verification in enterprise apps and enhancing compliance with data accessibility standards.


Challenges of Using Voice Recognition Authentication


Although everyone has a distinct voice, reliable speech recognition verification might be problematic in particular situations, such as when a user has a cold or a sore throat. It's important as well hard to restrict unauthorized access to the system by imitating other voices. The best way to go about this is to whitelist the voiceprints and save them in the Active Directory. Through this process, a voice recognition system user is added to a database of whitelisted members, whose voiceprints are utilized as the legitimate voiceprints for authentication.


Each member's distinct voice cadence is matched using the Active Directory to both a whitelist of authentic customer voiceprints and a blacklist of voiceprints associated with known fraudsters. If the suspect's voice matches a record in the blacklist database, passive fraud detection can be set up to provide a real-time notice as whitelist authentication takes place.
