Voice Biometrics

Speaker Verification

We provide a multi-modal digital identity verification through face and voice biometrics. One layer of security that can add more accuracy on detecting fraud is the voice(speaker) verification.

PresentID Speaker verification API/SDK checks whether two voices belong to the same person or not. This capability is potentially useful in call centers.

Voice Biometrics

We have proposed

We propose a deep learning-based method for speaker verification. Our team has worked on this project for more than 1 year and the accuracy has passed over benchmarks such as the accuracy of the paper by Andrew Zisserman Group at Oxford University. Contrary to other methods that are text-dependent, our system is text and language independent.

The processing speed of our model is less than 1 sec. The system identifies a person by just checking two voices with a length of 4 secs. Our system works perfectly in English, French, Spanish, German, Persian and Arabic, even in a noisy environment.
