Matthias Sperber

Machine Translation Researcher



I’ve recently joined Apple as a machine translation researcher. I completed my Ph.D. at the Institute for Anthropomatics at KIT in Germany, focusing on various aspects of speech translation. My advisor was Prof. Alex Waibel of KIT / CMU. I’ve conducted extended research stays at both CMU and the Augmented Human Communication Laboratory at NAIST in Japan, working closely with Prof. Satoshi Nakamura and Prof. Graham Neubig. Before working on speech translation, I conducted research on efficient human annotation paradigms in NLP and speech.
