This course will teach participants how to implement a complete spoken language system while providing opportunities to explore research topics of interest in the context of a functioning system. The course will produce a complete implementation of a system to access and manipulate email through voice only, for example to allow users to interact with the mail system over a telephone while away from their computer. In doing so the class will address the component activities of spoken language system building. These include, but are not limited to, task analysis and language design, application-specific acoustic and language modeling, grammar design, task design, dialog management, language generation and synthesis. The course will place particular emphasis on issues in task design and dialog management and on issues in language generation and synthesis.
