2.1.3. Using installed microphone network in the environment
An installed microphone network is used to recognize commands to call the robot. It can be hidden in
every room. This network is just used to call the robot. In front of him a simple gooseneck microphone is
used to command all predefined tasks.
Requirements:
Installation of a microphone-system in the environment
Adaption of simon to handle different microphones and activate them on demand
Adaption of simon to handle different acoustic models for different zones of signal processing
(e.g. comfort zone, call zone, communication zone)
Integration of a garbage model and voice activity detection
A solution of sound segmentation would be good but the implementation would exceed the
project time. Maybe there are some synergies with the results of other echord projects.
2.2. Zones of signal processing:
2.2.1. Call zone
Calling the robot, calling for help, security signals from everywhere in the environment
2.2.2. Communication zone
Be able to make a phone call (distance of 1 to 3 meters from a gooseneck microphone)
2.2.3. Comfort zone
High quality of communication between user and robot, command and control, dialog control, etc.
(directly in front of a microphone)
