Hi! Welcome to my Homepage!

I am currently working as a Research Associate in the Speech and Natural Language Processing group of CEN (Center for Computational Engg and Networking) at Amrita. My work is concentrated on design of speech interfaces and machine translation systems for Indian languages.
Earlier, I worked as a Design engineer in Speech and Audio group of SANYO LSI Technology India Pvt Ltd. I was involved in development and optimization of speech and audio codecs (ITU-T and 3gpp) on embedded platforms.
My interests lie in the areas of acoustical signal processing, spoken dialog systems and machine learning.

I completed my undergraduation in Electronics and Communication from Amrita Institute of Technology, Coimbatore. I worked on building a robust, multilingual speech recognizer for Tamil and Hindi for my undergraduate thesis.

What's New?

Recently I worked with researchers from TIER group, UC Berkeley in building spoken dialog systems for rural and illiterate users in Tamilnadu, India. Here are some of the pictures taken during our field studies. More details are available in a ICSI Press release about the project.

I worked on a cool project in SANYO on "Virtual 3D surround sound". It involved an array of technologies including Dolby Headphones (DH), Dolby virtual speakers(DVS) and SANYO 3D surround (S3S). These systems simulate 5 channel illusion in any conventional stereo headphones or speakers, rather than plainly downmixing the multichannel audio. Try out an example of the surround enhanced stereo file. (I have also included a downmixed version for reference).
