Nuance VocalPassword verifies a speaker during an interaction with a voice application such as an IVR or a mobile app. It compares a single repetition of a passphrase to the voiceprint that is stored in the system’s database. It can do this in any language, with any accent, and any call-quality.
With VocalPassword, authenticating to an IVR or a mobile app is as easy as speaking “My voice is my password.” The user doesn’t need to remember anything, or carry sensitive information with them. It gets them faster to the purpose of their call or puts them one step nearer to completing a transaction.
And by design, it sidesteps all the traditional security problems with information-based verification. It’s immune to current fraud techniques and enables companies to store voiceprints of known fraudsters to proactively prevent fraud from occurring.
Engage usVocalPassword 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.
Enrollment
To enroll a voiceprint in VocalPassword the customer is asked to speak the passphrase three times.
Verification
