The goal of the "ALIAS" project is to develop a speech controlled mobile robot system to support the elderly in everyday life. For this, the robot is not intended to replace relationships between people, but to help the user to maintain and extend existing contacts using modern telecommunications technology. The project's concern is to support the social integration of elderly people to avoid imminent isolation. In addition, to retain the quality of life, the user's cognitive activities are also to be stimulated.
In the context of the ALIAS project, the Project Group Hearing, Speech and Audio Technology of Fraunhofer IDMT covers the whole field of acoustic interaction between user and robot. This includes speech recognition, speech control, and acoustic analysis of the environment. For the necessary signal pre-processing, procedures of noise reduction, localization and direction filtering are used. On the application level, the project group focuses on the aspect of memory assistance (aided recall), based on knowledge gained from the GAL project.
