5th International Conference on Spoken Language Processing
GALAXY is a client-server architecture for accessing on-line information using spoken dialogue which was first introduced at ICSLP-94. It has served as the testbed for developing human language technologies for our group for several years. Recently, we have initiated a significant redesign of its architecture to enable many researchers to develop their own applications, using either exclusively their own servers or intermixing them with servers developed by others. This redesign was done in part due to the fact that GALAXY has been designated as the prototype reference architecture for the new DARPA Communicator Program. The new architecture, GALAXY-II, makes use of a scripting language for flow control to provide flexible interaction among the servers, and a set of libraries to support rapid prototyping of new servers. In this paper, we describe the new architecture in some detail, and report on the current status of its development.
