Lab Introduction

-History: CSLT was founded in February 2007. CSLT is led byfaculty members from research groups of the School of Information Science and Technology, including the Center for Speech Technology (CST) of the State Key Laboratory of Intelligent Technology and Systems, the Speech Group and the Speech-on-ChipGroup of the Department of Electronic Engineering, the Future Information Technology (FIT) R&D Center of Research Institute of Information Technology, as well as the Division of Computer Science and Artificial Intelligence of Tsinghua National Laboratory for InformationScience and Technology.

-Guideline: Keeping the guideline as "base on the applications, advocate the innovations, focus on the emphases and spur with long accumulation" in the mind,CSLT faces the challenges in the areas of speech and language processing technologies. Main research directions of the center include speech recognition, speaker recognition and language understanding. CSLT optimizes its resources allocation and effectively distributes human resources. Through exploring and setting up effective pattern of "cooperative of Industry, Education and Research", CSLT is to strengthen core competency in intellectual property through technology innovation and industrialization, and is to promote the development of applied fundamental research and technology innovation.

-Organization: CSLT has six research groups: Speech Recognition Group, Speaker Recognition Group, Speech-on-Chip Group, Intelligent Searching Group, Language Understanding Group and Resource and Standardization Group. In order to speed up the development and improve the research level, CSLT established an advisory committee that composed of famous experts in the world. They are: Victor Zue (MIT, IEEE Fellow, NAE member), B.-H. (Fred) Juang (GeorgiaTech, IEEE Fellow, NAE member)AWilliam Byrne (Cambridge), Dan Jurafsky (Stanford), Richard Stern (CMU)AFang Ditang (Tsinghua), Wu Wenhu (Tsinghua), and Liu Runsheng (Tsinghua).

-Location: 1-303, Information Science and Technology Building, Tsinghua University, Beijing, 100084, China.
