solution: Microphone installation
THE T.BONE TB312S gooseneck microphone
SAMSON CM12C hanging microphones
Different SAMSON CM12C hanging microphones with comparable quality to the gooseneck microphone
installed in the environment and one gooseneck microphone on the robotic platform could be a very
usefull solution, because the User needs nothing only the voice to call the robot, and when he stays in
front of him he can control the robot with the high quality gooseneck microphone.
3. Speech modelling
3.1. Preparation of the technical infrastructure
In the first step we prepared the technical infrastructure to be able to construct the German, Italian and
English speech models for this project. We installed a speech data server to collect speech data from Italy
and implemented a High Power Compilation-PC to create speech models. The scientific software like SSC
(Simon speech collector) and SAM (Simon acoustic modeler) is ready to use. The German speech model is
ready to use.
3.2. Investigation of speech models
3.2.1. German
3.2.1.1. Available German speech models
German Voxforge Speech model
Different speech models from simon listens, adapted to the target group from speakers in
different age ranges and for different microphone types (e.g. gooseneck microphone, hanging
microphone, headset). In the last recordings for our speech model database we included also
necessary word for the astromobile project (“astro”, etc.)
