Dr. A. Shahina M.Tech., Ph.D.,
Experience and Aim:
A. Shahina is a professor in the department of Information Technology at SSN. She has 14 years of teaching and research experience, with over 5 years of research exclusively in the field of Speech Processing, one of the widely growing and popular research areas. She aims to develop speech based clinical applications, and technologies for viable biometric person authentication systems through sustained research.
Shahina obtained her PhD from the department of Computer Science and Engineering at IIT-Madras, India. She also has an M.Tech from IIT-Madras and a B.E from Govt. College of Engineering, Salem. She has worked as a project officer for a DRDO-sponsored project at IIT-Madras.
Shahina has research interests in the areas of Speech Processing (using alternate anatomical speech sensors), Speech Applications, Man-Machine Interface, Pattern Recognition (especially of physiological signals) etc. Prior to joining SSN, Shahina has incorporated novel approaches to improve the perceptual quality of speech from alternate speech sensors. She has exploited this speech for developing robust speech systems in adverse environments. She has also proposed a novel approach for loudness enhancement of soft voices by manipulating the speech signal.
