The Pi is powerful enough to carry out speech recognition, as demonstrated by this voice-controlled robot arm.
The system is using the Julius open-source speech-recognition engine running on the Pi with the Linux Debian Squeeze distro.
In the demo the creator uses a microphone to command the arm to manoeuvre and open and close its grip. See more footage of the system in action.
