Dr. Alexander Waibel is a Professor of Computer Science at the  Language Technologies Institute (LTI) of Carnegie Mellon University (CMU), Pittsburgh, and at the Interactive Systems Labs of Karlsruhe Institute of Technology, Germany. He is the director of the International Center for Advanced Communication Technologies (interACT),. The Center works in a network with eight of the worldŐs top research institutions. The CenterŐs mission is to develop multimodal and multilingual human communication technologies based on advanced machine learning algorithms to improve human-human and human-machine communication. Prof. Waibel and his team developed many statistical and neural network learning algorithms that made a number of communication breakthroughs possible. These included early multimodal interfaces, first neural network speech and language processing systems, the first speech translation systems in Europe and USA (1990/1991), the worldŐs first simultaneous lecture translation system (2005), and Jibbigo, the worldŐs first commercial speech translator on a phone (2009).

            Dr. Waibel founded and served as chairmen of C-STAR, the Consortium for Speech Translation Advanced Research in 1991. Since then he directed many research programs in speech, translation, multimodal interfaces and machine learning in the US, Europe and Asia. He served as director of EU-Bridge (2012-2015), CHIL (2004-2007), two large-scale European multi-site Integrated Project initiatives on intelligent assistants and speech translation services. He also served as co-director of IMMI, a joint venture between KIT, CNRS, and RWTH.

            Dr. Waibel is an IEEE Fellow and received many awards for pioneering work on multilingual and multimodal speech communication and translation. He published extensively (>700 publications, >23,000 citations, h-index 79) in the field and received/filed numerous patents.

            During his career, Dr. Waibel founded and built 10 successful companies. Following the acquisition of Jibbigo by Facebook, Waibel served as founding director of the Language Technology Group at Facebook. He also deployed speech translation technologies in humanitarian and disaster relief missions. His team recently deployed the first simultaneous interpretation service for lectures at Universities and interpretation tools at the European Parliament.


Dr. Waibel received his BS, MS and PhD degrees at MIT and CMU, respectively
