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

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
