Technology assessment of advanced automation for space missions

Six general classes of technology requirements derived during the mission definition phase of the study were identified as having maximum importance and urgency, including autonomous world model based information systems, learning and hypothesis formation, natural language and other man-machine communication, space manufacturing, teleoperators and robot systems, and computer science and technology

Vers l'évaluation de systèmes de dialogue homme-machine : de l'oral au multimodal

International audienceEvaluating human-machine dialogue systems is not so efficient, objective, and consensual than evaluating other natural language processing systems. Oral and multimodal dialogue systems are still working within reduced applicative domains. Comparative and normative evaluations are then difficult. Moreover, the continuous technological progress makes obsolete and numerous the evaluating paradigms. Some solutions are still to be identified to improve existing methods and to allow a more automatic diagnosis of systems. The aim of this paper is to provide a set of remarks dealing with the evaluation of multimodal spoken language dialogue systems. Some extensions of existing paradigms are presented, in particular DQR/DCR, considering that some paradigms fit better multimodal issues than others. Some conclusions and perspectives are then drawn on the future of the evaluation of human-machine dialogue systems.L'évaluation pour le dialogue homme-machine ne se caractérise pas par l'efficacité, l'objectivité et le consensus que l'on observe dans d'autres domaines du traitement automatique des langues. Les systèmes de dialogue oraux et multimodaux restent cantonnés à des domaines applicatifs restreints, ce qui rend difficiles les évaluations comparatives ou normées. De plus, les avancées technologiques constantes rendent vite obsolètes les paradigmes d'évaluation et ont pour conséquence une multiplication de ceux-ci. Des solutions restent ainsi à trouver pour améliorer les méthodes existantes et permettre des diagnostics plus automatisés des systèmes. Cet article se veut un ensemble de réflexions autour de l'évaluation de la multimodalité dans les systèmes à forte composante linguistique. Des extensions des paradigmes existants sont proposées, en particulier DQR/DCR, sachant que certains sont mieux adaptés que d'autres au dialogue multimodal. Des conclusions et perspectives sont tirées sur l'avenir de l'évaluation pour le dialogue homme-machine

Review of Research on Speech Technology: Main Contributions From Spanish Research Groups

In the last two decades, there has been an important increase in research on speech technology in Spain, mainly due to a higher level of funding from European, Spanish and local institutions and also due to a growing interest in these technologies for developing new services and applications. This paper provides a review of the main areas of speech technology addressed by research groups in Spain, their main contributions in the recent years and the main focus of interest these days. This description is classified in five main areas: audio processing including speech, speaker characterization, speech and language processing, text to speech conversion and spoken language applications. This paper also introduces the Spanish Network of Speech Technologies (RTTH. Red Temática en Tecnologías del Habla) as the research network that includes almost all the researchers working in this area, presenting some figures, its objectives and its main activities developed in the last years
