Voice biometrics is the coolest one

So what exactly is voice biometrics? It is a mathematical probability model that can validate speaker identity on a live phone call. It is not magic but it works on signal processing algorithms. There are two stages in this. Enrollment, where we make the speaker provide 30 secs worth of speech, so that we extract unique features of his/her voice. This is scored through algorithms and stored in database as VOICE PRINT. This is once in the customer or user lifecycle. Authentication is live speech of 15-20 secs, which is compared against the voice print for verification. Enrollment can happen through mobile apps, phone calls and other equipment. We don’t store the actual voice recording of any enrollment or authentication. We store only the relevant mathematical values, to avoid reverse engineering. A decision to confirm or reject the live voice authentication, is done by the voice biometric server and decision conveyed back to the user interface. This can work with existing CRM records and entire data set can be given to the contact centre executive
