Details on how this is possible are on the developer's blog
We've been talking about Raspberry Pi for some time and people have found a lot of uses for this amazing little device. The ingenuity has gone a little further than anyone could imagine and it seems it will be possible to control robots using the mini PC.In a blog post on the official Raspberry PI blog, the developers of the mini PC have presented the work of Aon², an aerospace engineer that tested a speech recognition system using the Raspberry PI, in order to control a robot.
The speech recognition technology is called an LVCSR – a Large-Vocabulary Continuous Speech Recognition decoder. In this case, Raspberry PI is running Debian and has an USB microphone attached.
Detailed instructions about the process can be found on his website.
Raspberry Pi relies on an ARM processor with a clock speed of 700 MHz, 256 MB of RAM, an SD card slot and a 5V Micro USB connector that supplies the power. It also features RCA and HDMI ports.
