Intermodal binding between affective information that is seen as well as heard triggers a mandatory process of audiovisual integration. In order to track the time course of this audiovisual binding, event related brain potentials were recorded while subjects saw facial expression and concurrently heard auditory fragment. The results suggest that the combination of the two inputs is early in tim...
Both auditory and audiovisual speech synthesis have been the subject of many research projects throughout the years. Unfortunately, in recent years only very few research focuses on synthesis for the Dutch language. Especially for audiovisual synthesis, hardly any available system or resource can be found. In this paper we describe the creation of a new extensive Dutch speech database, containi...
This study examined fMRI activation when perceivers either passively observed or observed and imitated matched or mismatched audiovisual ("McGurk") speech stimuli. Greater activation was observed in the inferior frontal gyrus (IFG) overall for imitation than for perception of audiovisual speech and for imitation of the McGurk-type mismatched stimuli than matched audiovisual stimuli. This unique...
In this study we investigate previous claims that a region in the left posterior superior temporal sulcus (pSTS) is more activated by audiovisual than unimodal processing. First, we compare audiovisual to visual-visual and auditory-auditory conceptual matching using auditory or visual object names that are paired with pictures of objects or their environmental sounds. Second, we compare congrue...
Speech perception engages both auditory and visual modalities. Limitations of traditional accuracy-only approaches in the investigation of audiovisual speech perception have motivated the use of new methodologies. In an audiovisual speech identification task, we utilized capacity (Townsend and Nozawa, 1995), a dynamic measure of efficiency, to quantify audiovisual integration. Capacity was used...

We describe a systematic methodology for extending the audiovisual content description standards (MPEG-7 and TV-Anytime) with domain-specific knowledge descriptions expressed in OWL. The domain-specific descriptions of the audiovisual content metadata are completely transparent to applications and tools that use MPEG-7 and TV-Anytime, allowing them to use the domainspecific ontologies without a...
The present study investigated the cortical large-scale functional network underpinning audiovisual integration via magnetoencephalographic recordings. The reorganization of this network related to long-term musical training was investigated by comparing musicians to nonmusicians. Connectivity was calculated on the basis of the estimated mutual information of the sources' activity, and the corr...
In audiovisual composition, coupling montage moving images with music is common practice. Interpretation of the effect on an audioviewer's consequent interpretation of the composition is discursive and unquantified. Methodology for evaluating the audiovisual multimodal interactivity is proposed, developing an analysis procedure via the study of modality interdependent transient structures, expl...
