Voice Biometric Authentication

Voice biometrics is the science of using a person’s voice as a uniquely identifying biological characteristic in order to authenticate them

Voice biometrics is the science of using a person’s voice as a uniquely identifying biological characteristic in order to authenticate them. Also referred to as voice verification or speaker recognition, voice biometrics enables fast, frictionless and highly secure access for a range of use cases from call center, mobile and online applications to chatbots, IoT devices and physical access.

Like other biometric modalities, voice identification offers significant security advantages over authentication methods that are based on something you know (like a password or answer to a “secret” question) or something you have (like your mobile phone). Voice biometrics also improves the customer experience by removing frustration associated cumbersome login processes and lost and stolen credentials.

Voice Biometric Advantages

  • Improve security and minimize breaches due to compromised passwords, phishing, etc.
  • Enhance the customer experience with fast, frictionless authentication
  • Reduce threats by identifying known fraudsters
  • Instantly identify users and personalize the interaction
  • Free agents from time spent verifying users and resetting passwords
  • Enable natural login for digital channels, including chatbots and virtual assistants

How Voice Biometrics work

Voice biometric systems work by creating a voice print or “template” of a person’s speech. A template is created, encrypted and stored for future voice verification only when a user opts in or “enrolls”. Typically, the enrollment process is passive, meaning a template can be created in the background during a user’s normal interaction with an application or agent.

The use of voice biometrics for authentication is increasing in popularity due to improvements in accuracy, fueled largely by advances in AI, and heightened customer expectations for easy and fast access to information. Frequent password-associated data breaches are another reason for broader adoption as companies look for ways to better protect customer data.

Types of Voice Biometrics

Voice biometric authentication can be accomplished using text-dependent speaker recognition or text-independent voice verification.

Text dependent voice verification is where a person speaks a specific passphrase, usually consisting of two to three words, like “My voice is my passphrase.”

Text independent voice verification is a passive voice biometric approach whereby the user can say anything, enabling authentication to quickly happen in the background during their normal interaction with an agent, IVR, or application.
