Most of the current biometric-based authentication options have their limitations. Fingerprints, face, and iris are all static and can be replaced by malicious actors. There are cases when fingerprint databases leak to the darknet
and then being sold on the cybercrime markets. Furthermore, such leaked fingerprints may be used to 3D print replicas
with sufficient quality to fool fingerprint scanners!
In turn, voice is as unique as a fingerprint but is much harder to replicate. Our bodies are matchless, which directly affects our voices. Pronunciation, emphasis, speed of speech, accent, and timbre vary from person to person, and it is almost impossible to mimic all these parameters simultaneously.
Voice biometrics is built around using the voiceprint as an additional security token for more effective verification and authentication. Here are two types of voice biometrics. Let's have a look at them.
