Our research team is now focussed on strengthening our lead in two application domains related to audio processing: (i)Use of speech for biometric authentication and development of counter measure to prevent voice based identity hacking; (ii)Development of heart and lung sound based diagnostic tools for physician's aid. In neuro-signal processing, the team extends our work on how brain works for complex cognitive tasks like perception, imagination, preference decision etc. Going forward, we would like to explore how integration of these three verticals open up newer understanding and newers solutions. We also take up sub-problems leveraging our strengths in these to attend specific R & D needs. In each of the three areas of investigation, we have collaborating scientists, medical experts extending necessary support to our team.
