Homepage of Bjoern Hoffmeister

My personal research interests are automatic speech recognition and speech translation.
I am writing my PhD thesis about "Bayes Risk Decoding and System Combination for Large Vocabulary Continous Speech Recognition Systems".

You can find me in room 6013 of building E2. Telephone: +49 241 80-21620. E-Mail: hoffmeister@cs.rwth-aachen.de
