How it works

VocalPassword provides voice platforms, web servers and authentication servers with identity verification capabilities through the use of voice biometric matching engines. Once the customer’s voice is captured speaking the passphrase, the audio is transferred to VocalPassword along with a claimed identity. The captured voice is then compared with the relevant stored voiceprint and a verification result is provided by VocalPassword. In parallel, the captured voice is also compared to a fraudster voiceprint database, also known as a blacklist, to check if the voice belongs to a known malicious individual.
