‘SpeechXRays’ voice biometrics, face and voice recognition project

Many congratulations to radar expert Professor Hugh Griffiths and Visiting Professor Clay Stewart who have been awarded almost £300k from the European Commission Horizon 2020 funding programme. The 3 year project titled ‘SpeechXRays’ involves an international team of academic and industry partners from France, UK, Romania, Estonia and Greece working on multi-channel biometrics combining acoustic and machine vision analysis of speech, lip movement and face.

The SpeechXRays digital security project will develop and test in real-life environments a user recognition platform based on voice acoustics analysis and audio-visual identity verification. SpeechXRays aims to outperform state-of-the-art solutions in the following areas:

• Security: high accuracy solution (cross over accuracy1 of 1/100 ie twice the commercial voice/face solutions)
• Privacy: biometric data stored in the device (or in a private cloud under the responsibility of the data subject)
• Usability: text-independent speaker identification (no pass phrase), low sensitivity to surrounding noise
• Cost-efficiency: use of standard embedded microphone and cameras (smartphones, laptops)

The project will combine and pilot two proven techniques: acoustic driven voice recognition (using acoustic rather than statistical only models) and multi-channel biometrics incorporating dynamic face recognition (machine vision analysis of speech, lip movement and face).The vision of the SpeechXRays project is to provide a solution combining the convenience and cost-effectiveness of voice biometrics, achieving better accuracies by combining it with video, and bringing superior anti-spoofing capabilities. The technology will be deployed on 2000 users in 3 pilots: a workforce use case, an eHealth use case and a consumer use case.
