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.
Massive advances in neural networks over the past 2-3 years have enabled the development of voice biometric algorithms that are faster, more accurate, and can authenticate users with a smaller amount of speech. In fact, ID R&D is now able to exceed the accuracy of a 4-digit PIN in many use cases.
Like other biometric modalities, voice biometrics offer 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.
