Dialogue Systems / Dialogové systémy

About

This course is a detailed introduction into the architecture of spoken dialogue systems, voice assistants and conversational systems (chatbots). We will introduce the main components of dialogue systems (speech recognition, language understanding, dialogue management, language generation and speech synthesis) and show alternative approaches to their implementation. The lab sessions will be dedicated to implementing a simple dialogue system or a selected component.

Logistics

The course will be mostly in English, but we're happy to explain in Czech, too.

Lectures: Tue 10:40 S11
Labs: Wed 9:00 SU1
