Main features

The main features of the das-Peak voice biometrics engine are:

  • Minimum duration: Allows verifying audios with a minimum voice duration of 3 seconds, an industry-record duration. Verification time: 0.14 seconds for comparing a biometric vector and an audio.
  • Text-independent: Allows to compare phrases with different content. That is, the user does not have to remember any phrase or have to read the same phrase to be authenticated.
  • Language-independent: Allows to compare voices in different languages. The biometric voice engine has been specially trained for the following languages: English, Spanish, German, French, Italian, Chinese, Taiwan, Dutch, Estonian, Persian, Turkish, Welsh, Kabyle, Catalan and Euskera.
  • Certified technology: Biometric engine performance rated Internationally by NIST and by the SdSV as one of the leading solutions in the market. (e.g. In the Short-duration Speaker Verification challenge 2020 (SdSV), Veridas achieved a 0.0769 %, being the 2th in single system)
  • Minimum size biometric vector: The biometric vector size is 1.1Kbytes.
  • Voice activity detection: Compute the total quantity of voice in the input audio to accept a verification request.
  • Noise detection: Compute the total quantity of noise in the input audio to accept a verification request.
  • Voice Authenticity Detection: given an audio input it is possible to detect if the voice recorded in the audio is authentic or is a replay attack spoof performed by reproducing a voice through a smartphone speakers or a high fidelity speakers.
  • Different Calibration modes: Include different calibration to obtain better verification/identification results depending on the use case (telephone channel, lossless audio). If the use case is the telephone audio, the customer must use the parameter calibration="telephone-channel". If the customer uses SDKs for audio capture, the parameter calibration="lossless-audio" should be added.
  • Audio capture SDKs available: To achieve the best performance, it is advisable to record audios under specific conditions (link to audio constraints). VERIDAS provides a variety of proprietary SDKs to ensure smooth audio recording, compatible with iOS and Android.
  • VERIDAS does not store any personal data in the cloud: all the user information (i.e., both the audio recordings and the voice credentials) is immediately deleted after processing.
