Language Technologies Research Centre (LTRC) Visit Center's Homepage

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

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

LTRC is also a lead participant in nation-wide mission-mode consortia projects to develop deployable technology in the areas of Indian Language Machine Translation, English to Indian Language Machine Translation, and Cross Language Information Access (search engines).

NLP-MT Lab
The NLP-MT lab does fundamental work on developing grammatical as well statistical models of language. Linguistic approaches are combined with machine learning leading to new theories and technology development. This has resulted in higher accuracy parts-of-speech taggers, chunkers, constraint-based parsers as well as broad coverage statistical parsers, and semantic analyzers for Indian languages on the one hand, and annotated data including dependency tree banks, discourse banks, parallel corpora, etc. on the other.

Anusaaraka Lab
Anusaaraka lab is concerned with development of machine translation systems which in addition to the usual machine translation output also allows a user to understand the source language text in a pseudo target language. For example, a reader who knows Hindi (the target language) would be able to read the English source text, in a pseudo Hindi output after a small amount of training.

Search and Information Extraction Lab (SIEL)
The Lab focuses on solving research problems in the areas of Information Retrieval and Extraction using NLP techniques.
SIEL is engaged in building technologies for personalized, customizable and highly relevant information retrieval (IR), Information Extraction (IE) and Information Access (IA) systems. Current research includes summarization, cross language information access systems and building vertical search engines. Information Retrieval and Access in Indian languages is one of the major goals of the lab.

Speech lab
The long term goal of the speech group is to develop robust speech systems for applications such as speech translation, phonetic engine for Indian languages, speaker recognition for biometrics, and dialog systems in speech mode.
The research focus of the group is to address issues involved in processing speech for phonetic engine, speech synthesis, speaker recognition, speech enhancement, speech coding, information retrieval in speech mode, and multimodal biometrics. The group is also engaged in developing speech systems for Indian languages with emphasis on language modeling, prosody modeling and pronunciation modeling.

Achievements
LTRC has developed a natural sounding text-to-speech (TTS) system for Indian Languages (Telugu & Hindi). The above engine has been integrated into a Reading Software for the Visually Impaired, and released by President of India in March 2003.
