Professor: LEO WANNER
The couse covers the central themes involved in the interaction with intelligent agents through the use of natural language, with emphasis on dialogue and language generation. We will also study planning techniques applied to the theory of speech acts and the use of rhetorical structures, both for controlled dialogues as for dynamic and non-cooperative dialogues. Regarding analysis and generation of language, students will learn robust and incremental techinques capable of dealing with partial, and even ungrammatical discourse, as it's typical of spontaneous dialogues. We will also look at the design of dialogue architectures, and analyze the use of dialogue in "chatbots" and videogames. The course also covers spoken interaction including aspects on automatic speech recognition, atuomatic speaker recognition, and text-to-speech synthesis.
