The ambitious goal of the project Verbmobil 1 is the development of a portable speech-to-speech translation system dealing with face-toface dialogs. It constitutes a new generation of translation sytems in which spontaneously spoken language, speaker independence and speaker adaptability are among the main features. Verbmobil brings together researchers from the fields of speech processing, computational linguistics and artificial intelligence and goes beyond the state of the art in these areas. Besides the speech and language processing issues, the specific constraints of the project represent an extreme challenge on the part of project management, software engineering and test and evaluation of the system: -size and complexity: 150 researchers from 29 organizations at different sites on three continents are involved in the software development, -integration of heterogeneous software: in order to reuse existing software, hardware and know-how, only a few restrictions were given to the partners. In the following article we describe the Verbmobil scenario, the system architecture and the system evolution.
Verbmobil represents a new generation of speech-to-speech translation systems in which spontaneously spoken language, speaker independence and adaptability as well as the combination of deep and shallow approaches to the analysis and transfer problems are the main features. The project brought together researchers from the fields of signal processing, computational linguistics and artificial intelligence. Verbmobil goes beyond the state-of-the-art in each of these areas, but its main achievement is the seamless integration of them. The first project phase (1993–1996) has been followed up by the second project phase (1997–2000), which aims at applying the results to further languages and at integrating innovative telecooperation techniques. Quite apart from the speech and language processing issues, the size and complexity of the project represent an extreme challenge on the areas of project management and software engineering:[bull ] 50 researchers from 29 organizations at different sites in different countries are involved in the software development process,[bull ] to reuse existing software, hardware, knowledge and experience, only a few technical restrictions could be given to the partners.In this article we describe the Verbmobil prototype system from a software-engineering perspective. We discuss:[bull ] the modularized functional architecture,[bull ] the flexible and extensible software architecture which reflects that functional architecture,[bull ] the evolutionary process of system integration,[bull ] the communication-based organizational structure of the project,[bull ] the evaluation of the system operational by the end of the first project phase.
