LTRC addresses the complex problem of understanding and processing natural languages in both speech and text mode.

LTRC conducts research on both basic and applied aspects of language technology. It is the largest academic centre of speech and language technology in South Asia. LTRC carries out its work through four labs, which work in synergy with each other, as listed above.


In the NLP-MT Lab at LTRC, IIIT-H, work is undertaken in many different sub-areas of NLP including syntax and parsing, semantics and word sense disambiguation, discourse and tree banking, machine translation, creation of linguistics resources etc. Computational models are built inspired from linguistics, which are combined with machine learning techniques.
