Speech recognition is very hard to implement. Even home computers using lots of CPU cycles cannot completely understand human voice every time and be reliable at it. It may be doable if you have all day on your hands for months and you decide to use a much more powerful IC such as the DSPIC30 series. For this reason I have never heard of anybody actually accomplishing this.

The microphone will also need amplification circuitry and a good quality DAC converter. The other problem is the device will not know when to stop moving left or right unless they constantly said stop and so it would stop suddenly and the user would then need to say go again. this is less ergonomic for people to use than using a much cheaper and simpler joystick.

Unless you make very reliable code it would be a hazard as well because it could misunderstand you and so the user may find themselves in the wall :D

Edit: Actually i found a DSPIC30 libary here for speech reconition: **broken link removed**
