Task 5.1: Task Objective

Although hybrid HMM/ANN speech recognition systems appear to be efficient models, we also believe that new developments are necessary to further boost this technology. On the other hand, recent developments in systems trying to model some kind of auditory/perceptual properties [14] have been relatively successful. We however believe that hybrid HMM/ANN systems are potentially more flexible and better adapted to model some important perceptual properties.

The goal of this task is thus to investigate, develop and test new recognition systems based on perceptual properties and able to take full advantage of the HMM/ANN framework (i.e., properties that would be difficult to model outside the HMM/ANN framework).
