Speech translation for French in the NESPOLE! European project

This paper presents CLIPS laboratory activities in the context of the NESPOLE! European project, exploring future applications of automatic speech to speech translation in ecommerce and e-service sectors. The scientific and technological research issues particularly addressed in order to improve current experimental speech-to-speech translation systems, are: robustness, scalability, and cross-d...

Architecture and Design Considerations in NESPOLE!: a Speech Translation System for E-commerce Applications

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...

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...

Speech-to-speech translation system evaluation: results for French for the NESPOLE! project first showcase

In this paper we give the results of a set of evaluations conducted in the context of a speech to speech translation project (NESPOLE!). The chosen situation involves a client (French, German, American) talking to an Italian travel agent (both using their own language) to organize a stay in Italy. Fives series of evaluation were conducted on the same data set. The first series concerned the Aut...
