This paper describes decision tree methodology and shows how it has been adapted to three diierent problems in speech recognition and understanding at CRIM and at FORWISS. The three problems are: 1. Development of context-dependent phone models (work carried out by CRIM researchers and partly inspired by FORWISS work on polyphones). Here, decision trees determine a characterization of the conte...

BACKGROUND Atherosclerosis is enhanced in arterial segments exposed to disturbed flow. Perturbed shear stress increases the expression of oxidation-sensitive responsive genes (such as ELK-1 and p-CREB). Polyphenolic antioxidants contained in the juice derived from the pomegranate contribute to the reduction of oxidative stress and atherogenesis during disturbed shear stress. AIM OF THE STUDY ...

The increasing availability of carefully designed and collected speech corpora opens up new possibilities for the statistical estimation of formal multivariate prosodic models. At Apple Computer, statistical prosodic modeling exploits the Victoria corpus, recently created to broadly support ongoing speech synthesis research and development. This corpus is composed of five constituent parts, eac...

In acoustic and visual synthesis based on concatenation of speech units such as demisyllables, the recording of these units is normally taken from nonsense utterances where the demisyllable in question is pronounced in a non-focal position. In the present investigation, the relation between the lip movements in focal and non-focal position is studied and a computational model is hypothesised. 1...

Within the EC-funded project SQEL, the German EVAR spoken dialogue system has been extended with respect to multilinguality and multifunctionality. The current demonstrator can handle four di erent languages and domains: German, Slovak, and Czech (and their national train connections), and Slovenian (European ights). The SQEL demonstrator can also access databases on the WWW, which enables user...
