Abstract:
We study by statistical means the authentication logs obtained from the workforce use case of the SpeechXRays project (http://speechxrays.nipne.ro) to investigate the sensitivity of the SpeechXRays multi-modal (voice and face) biometrics system with respect to phonems and transitions between phonems. The logs to which the analysis pertains correspond to more than 600 users and more than 2500 entries. The logs do not include any personal data of the users (in compliance with the requirements of the GDPR) and contain only the authentication scores and the corresponding utterances.
