Christian Fuegen

Research Scientist

I joined Meta as a Research Scientist in 2013 due to the acquisition of Mobile Technologies. At Mobile Technologies, I was one of the core developers of “Jibbigo”, an on-device speech-to-speech translator for mobile devices, where I worked from 2007 until 2013, first as a research scientist and later as director of research.

I received a doctorate for my work on simultaneous translation systems of lectures and speeches from University of Karlsruhe (TH) in 2008 in which I developed core components for a first-ever simultaneous lecture translation system, including innovations in speech recognition, segmentation, adaptation and work on real-time and latency requirements for simultaneous speech translation systems.

Besides this, I have worked on a wide range of topics in the field of speech processing, speech translation and user interfaces, and I’ve participated in numerous international speech-to-text evaluation campaigns on conversational telephone speech, meetings, lectures and European parliament plenary speeches. I also participated in the development of the single pass Ibis speech-to-text decoder used for these evaluations.
