A major deficiency in state-of-the-art automatic speech recognition (ASR) systems is the lack of robustness in additive and convolutional noise. The model of auditory perception (PEMO), developed by Dau et al. (1996a) for psychoacoustical purposes, partly overcomes these difficulties when used as a front end for automatic speech recognition. To further improve the performance of this auditory-b...

In this section, we briefly present the formalism we use. This formalism aims at describing the state of a system and its dynamic behaviour in an algebraic framework [DG 94]. It was first introduced in a case study on a formal specification of the embedded safety part of an automatic subway pilot [DM 91], [Dau 92], [DGM 93], in order to cope with the large number of variables whose values made ...

Although some online communities have been able to produce high quality products and to engage thousands of users, community designers usually struggle to engage new users and increase the level of contribution of current users. Some researchers have explored approaches to persuade users to collaborate. An important strand of this research area is based on sending messages to the current users ...

This paper describes a graphical user interface that provides intelligent help to the users of an emailing system. The graphical user interface is called Intelligent Mailer (I-Mailer). I-Mailer monitors users while they work; in case a user is believed to have made a mistake, the system intervenes automatically and offers advice. In order to provide individualised help, the system keeps informa...
