Cassandra smart-home system description

This paper presents the architecture and technologies used to develop a voice controlled system for home automation named Cassandra. We start with the goals of the project and a system description, then focusing on the main components and the way they interact with each other. We exemplify with a scenario where we ask the house to turn the lights off, going step-by-step over the communication sequence between the modules involved. The purpose of this paper is for the reader to get an overview of how the system works, without going deep into technical details.
