Carnegie Mellon University Language Technologies Institute

What Carnegie Mellon University Language Technologies Institute does

The Language Technologies Institute (LTI) is a research and graduate education institute within Carnegie Mellon University's School of Computer Science, founded in 1966 and headquartered in Pittsburgh, Pennsylvania. LTI educates graduate students through five degree programs — the Ph.D. in Language and Information Technology, the research-based Master of Language Technologies, and three professional master's programs (Intelligent Information Systems, Artificial Intelligence and Innovation, and Computational Data Science) — while conducting research across more than 20 areas including natural language processing, computational linguistics, speech processing, machine translation, information retrieval, multimodal computing, and machine learning. Its research outputs include widely cited open-source platforms and datasets such as the Lemur Project (Indri and Galago search engines with ClueWeb datasets), Scone knowledge-base system, Sphinx speech recognition, FestVox voice toolkit, PhonBank and TalkBank linguistic corpora, LightSIDE text mining tools, and historical systems like the KANT machine translator.

LTI operates as a nonprofit academic unit and does not publish commercial revenue; funding flows through Carnegie Mellon university allocations, federal research grants (NSF, DARPA, IARPA), industry partnerships, and tuition. Its customer segments are graduate students (primary), industry partners seeking research collaboration and talent, and other research institutions for cross-institutional work. Distribution of educational programs runs through CMU SCS centralized admissions, while research outputs are distributed globally via open-source releases, publications in top venues (NeurIPS, ICLR, ICML), and collaborative networks such as the interACT international research center connecting eight top institutions. Faculty include pioneers such as Alexander Waibel (h-index 80, co-developer of the Time-Delay Neural Network), Yiming Yang (h-index 81, co-author of XLNet), Jamie Callan (h-index 73), and Carolyn Rosé (300+ peer-reviewed articles), with joint appointments extending the institute's footprint to Karlsruhe Institute of Technology and Japan's National Institute of Informatics.
