About

Currently working on analysis of EEG recorded during meditation, sleep, deep breathing with breath-hold, and disorders of consciousness. Creating DNN-based speech recognition technology, scalable to new languages. Created a reading machine for the blind for printed text in Kannada & Tamil. Using our Tamil OCR, Worth Trust Chennai has converted over 500 printed books to Braille books. Ramakrishna Mission, Pondicherry University Library, Mitra Jyothi, Mathruchchaya, Samrita Trust, Vision Through Ears use our Tamil and Kannada OCR. We also have online handwriting recognition engines for Tamil and Kannada. Our text-to-speech (TTS) conversion demo for Tamil and Kannada is on MILE lab website.
