Current Projects

Bilingual OCR as part of National Language Translation Mission

To develop and deploy a comprehensive OCR for Kannada language, that has the best accuracy in the world. It can handle old Kannada script (Halegannada) letters, Kannada numerals, interspersed English words, Indo-Arabic numerals and other common symbols
Bilingual OCR is funded by Ministry of Electronics & Information Technology (MeitY), TDIL division (Technology Development for Indian languages), GOI

Multimodal recognition of ancient manuscripts

Experts read the palm-leaf manuscripts in Tigalari or Grantha and a scribe writes it using Devanagari, Kannada or Tamil script. Speech and handwriting will be recognized in a language and vocabulary-independent manner and the text reconstructed in the original script.
IMPRINT-2 project funded by MHRD

Past Projects

A comprehensive review and meta-analysis of factors that enhance the readiness level of the immune system and also those that impair immunity

A comprehensive study and meta-analysis of factors that damage or impair the immune system; adaptogens that can increase the body's ability to overcome the damaging effects of stress and a critical meta-analysis of existing knowledge, protocols and best practices from peerreviewed SCI publications on yoga, pranayama and meditation for improving the immune system.
This project is funded by Department of Science and Technology under SATYAM Special call to combat COVID 19, GOI

Study of deautomatization in meditators

Study of cognitive control and deautomatization in long term Brahmakumaris Rajayoga meditators to evaluate the effectiveness of different meditation techniques as training tools to enhance cognitive control and deautomatize habitual responses.
DST CSRI (Cognitive Science Research Initiative) funded postdoc scheme

Speech Recognition for Indian Languages

We are working on large vocabulary automatic speech recognition system for Tamil, Kannada, Hindi and Sanskrit while trying to address the infinite vocabulary problem by using sub-word unit based language models. We also address the problem of data insufficiency by cross-lingual and multi-lingual acoustic model training.
Kannada ASR funded by Dept. of Kannada and Culture, Govt. of Karnataka

Study of driver fatigue and emotion

Study to understand the effect of Indian traffic situations on alertness, physiological and emotional status of the drivers and how accurately they judge their own driving fitness which helps in detection of fatigue in drivers.
A Wipro-IISc Research and Innovation Network project

Document Image Super-resolution

In this project, our task was to enhance the quality of document images using deep neural architectures, thus improving the accuracy of recognition algorithms

Online Hindi Handwritten Recognition

Online handwritten word is generated as X-Y coordinates of pen like device applied on touch sensitive screen. X-Y coordinates of pen tip are recorded as time dependent signal. Pen-down state occurs when the pen touches the screen and pen-up state occurs when pen is lifted from the screen.

Speech Enhancement Approaches

In the past decade, there has been tremendous improvements in the field of automatic speech recognition (ASR). Despite these, the performance of an ASR system degrades significantly in the presence of noise due to the mismatch between the training and test environments.
