More specifically we will emphasize the automation of various processes based on the extraction and analysis of digital media, through speech signals and images. Currently, there are many productized systems for personalization and recommendation of digital media content as well as various services in different areas. Most of them are developed with human-machine interaction in mind. Usually, this is done through a conventional use of a mouse and a keyboard.
