Galatea is a software toolkit to develop a human-like spoken dialog
agent. In order to easily integrate the modules of different characteristics including
speech recognizer, speech synthesizer, facial animation synthesizer[ facial-image
synthesizer ] and dialog controller, each module is modeled as a virtual machine
having a simple common interface and connected to each other through a broker
(communication manager). Galatea employs model-based speech and facial animation[
facial-image ] synthesizers whose model parameters are adapted easily to
those for an existing person if his/her training data is given. The software toolkit
that runs on both UNIX/Linux and Windows operating systems will be publicly
available in the middle of 2003 [1, 2]
