For quite some time I have been active as a researcher in the world of Human Language Technology. Initially as a post-doc in Düsseldorf and Ulm, then at the illustrious Flemish company Lernout and Hauspie, and since 1998 with great pleasure as a researcher HLT at the University of Twente.

The first projects focused on human-machine (telephony) dialogues. Later on, the focus shifted to Large Vocabulary Speech Recognition: the recognition of spontaneous spoken speech in meetings, interviews, over the phone and more.

A neatly pronounced CV (in Dutch) with almost perfect recognition can be found here on my own website.

In the press

In recent years I have occasionally "performed" in the media. This means that there have been a few short TV and Radio interviews with me. I tried to collect all these broadcasts and got them through the speech recognizer: baker eats your own bread :-).

There is also 2x a piece in the newspaper appeared. Finally I wrote quite a few pieces for all kinds of magazines and websites. If I have written it all by myself, I call it a blog and it is under the Blogs, if I was interviewed (and then I could rewrite the whole piece myself anyway), then it comes under Web.

The overview of these "press moments" can be found here.
