Research Description

Renato De Mori, former director and now emeritus professor at the McGill School of Computer Science and at the University of Avignon (France), has been scientific leader of the European Project LUNA in which research on Spoken Language Understanding (SLU) was performed using real-life data acquired for telephone services. He is now working on the DECODA project on human/human conversation analysis with data collected in the call centre of the RATP public transportation system in Paris.

Renato De Mori is Fellow of the IEEE Computer Society and has been Distinguished Lecturer of the IEEE Signal Processing Society. He is Associate Editor of the IEEE Transactions on Audio, Speech and Language Processing, has been chief Editor of Speech Communication, Associate Editor of the IEEE Transactions on Pattern Analysis and Machine Intelligence and other international journals. He is general chairman of INTERSPEECH 2011.

His research activities include the generation of concept hypotheses from signs extracted in continuous, spontaneous telephone speech. Various approaches are used in the ongoing research including continuous space language modelling, conditional random fields and other classifiers, stochastic methods for shallow parsing. Concept hypotheses are composed into semantic structures of which confidence indicators are evaluated. Conceptual structures are also validated using large context information, coming, for example, from dialogue histories. Aspects of dialogue management design are also investigated.

Research on acoustic features, speech processing and denoising for Automatic Speech Recognition (ASR) has been conducted leading to feature combination methods with which significant improvements in the accuracy of the generation of concept hypotheses have been obtained.
