My current research interests are
| Computational modelling of learning Computational cognition |
ACORNS: Acquisition of Recognition and Communication Skills. This project aims at building a computational model for learning the skills for recognition and communication, based on a small number of elementary characteristics of learning (perception, representation, storage, access/recall, abstraction/generalisation). Partners: Lou Boves, Hugo Van hamme, Roger Moore, Unto Laine, Bastiaan Kleijn and colleagues. |

Speech recognition by humans and by machines |
in collaboration with (among others) Odette Scharenborg. Katrin Kirchhoff and I were guest editors for Speech Communication for a special issue on Bridging the gap between human and automatic speech recognition (Vol. 49, May 2007). |
|
Pronunciation variation
Articulatory features |
Work on pronunication variation and HMM topologies is carried out by Annika Hamalainen. In collaboration with Bert Cranen we look into the use of articulatory features and Bayesian Networks for ASR.

Phonetic details in speech |
Work in the context of the European Sound-2-Sense project is carried out by Michele Gubian and Barbara Schuppler.

| Mathematics | Click here for a joint paper with Matthijs Coster on the relation between Hamilton walks on the hypercube and Fibonacci matrices. One of the underlying results required has been incorporated into the on-line database of integer sequences (see here). |
| Multimodal dialogue | The COMIC project (IST, FP5, 2002-2005) focused on defining generic cognitive models for multimodal interaction (speech and gestures) and to evaluate these in a number of demonstrators. When involved in a multimodal man-machine dialogue, people show very different behaviour with respect to modality switches and cross-modal error correction. See the COMIC-website for publications. |
| ASR | From 1995 until end of 2001, I joined the ASR research group of Lernout & Hauspie Speech Products in Wemmel (Belgium). Among our colleagues were Hugo Van hamme, Filiep Vanpoucke, Filip Van Aalten, Tom Claes, Bart d'Hoore, Kristin Daneels, Philippe Gelin, Martine Lapere, Marc Hogenhout, Frederic Beaugendre, Hong Xu and many others. |
| Vowel systems | In 1991, I defended my PhD thesis on Vowel Systems at the University of Amsterdam (supervisor Louis Pols). The aim was to describe the variation observed in vowel systems across languages in the world by using basic physical principles (minimizing articulatory effort while optimizing perceptual contrast). See e.g. here. More recently, the topic received renewed interest by e.g. Bart de Boer (see pdf). |
