The NESPOLE! Speech-to-Speech Translation System

A Multi-Perspective Evaluation of the NESPOLE! Speech-to-Speech Translation System

Performance and usability of realworld speech-to-speech translation systems, like the one developed within the Nespole! project, are affected by several aspects that go beyond the pure translation quality provided by the underlying components of the system. In this paper we describe these aspects as perspectives along which we have evaluated the Nespole! system. Four main issues are investigate...

Not only Translation Quality: Evaluating the NESPOLE! Speech-to-Speech Translation System along other Viewpoints

Performance and usability of real-world speech-to-speech translation systems, like the one developed within the Nespole! project, are affected by several aspects that go beyond the pure translation quality provided by the Human Language Technology components of the system. In this paper we describe these aspects as viewpoints along which we have evaluated the Nespole! system. Four main issues a...

The NESPOLE ! Multimodal Speech-to-Speech Translation System: User Based System Improvements

This work discusses the results of two user studies aiming to evaluate the NESPOLE! speech-to-speech translation system, which provides for multilingual and multimodal communication in the tourism and in the medical domain, allowing users to interact through the Internet by sharing maps, web-pages and pen-based gestures. The purpose is to investigate the overall effectiveness of the combination...

Balancing Expressiveness and Simplicity in an Interlingua for Task Based Dialogue

In this paper we compare two interlingua representations for speech translation. The basis of this paper is a distributional analysis of the C-star II and Nespole databases tagged with interlingua representations. The C-star II database has been partially re-tagged with the Nespole interlingua, which enables us to make comparisons on the same data with two types of interlinguas and on two types...

Enhancing the Usability and Performance of NESPOLE! — a Real-World Speech-to-Speech Translation System

Nespole! 1 is a speech-to-speech machine translation project designed to provide fully functional speech-to-speech capabilities within real-world settings of common users involved in e-commerce applications. The project is a collaboration between three European research groups (IRST in Trento, Italy; ISL at Universität Karlsruhe (TH); and CLIPS at Université Joseph Fourier in Grenoble, France),...
