A data-driven methodology for the production of multilingual conversational systems

This paper describes a data-driven methodology for the design of multilingual conversational systems. The work presented here covers the various aspects of bootstrapping and deploying multilingual systems, such as phone set definition, acoustic modeling, language modeling, and language understanding. For the initial system domain, a Directory Assistance Service has been chosen. Whereas former approaches focused more on the multilinguality of single components of a dialog system we will cover the whole speech-to-speech process of a conversational system.
