Voice biometrics

Speaker verification

We provide multimodal digital identity verification through facial and voice biometrics. A security test that can add more accuracy to fraud detection is voice (speaker) verification.

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

We have proposed a deep learning-based method for speaker verification. Our team has worked on this project for over a year and the accuracy exceeded criteria such as the accuracy of the Andrew Zisserman group paper from the university of oxford. Unlike other text-dependent methods, our system is text- and language-independent.

Our model's processing speed ​​is less than 1 sec. The system identifies a person by simply checking two voices lasting 4 seconds. Our system works perfectly in English, French, Spanish, German, Persian and Arabic, even in a noisy environment.
