robotsrule writes "Robosapien Dance Machine, a free, open source program hosted on SourceForge, now uses the CMU Sphinx 3.5 speech recognition engine. The Sphinx 3.5 engine is also a free, open source program on SourceForge. You can now control your Robosapien robot using just your voice as well as build fun complex scripts to make your Robosapien robot dance, do comedy skits, and other performances. Currently the software uses the USB UIRT infrared transceiver to talk to the robot. Support for other infrared devices is being added this month. There is a short unrehearsed movie of the robot responding to voice commands that you can watch."
