Voice Recognition with BOE Bot

I own the Parallax BOE-Bot USB version, and am trying to implement some sort of voice recognition to control its movements with speech. I've read a few suggestions saying the VR stamp module is a good choice, or the SR-07 voice recognition kit. However, I don't think any of these will fit on the Parallax Bot, with the "Board of Education".

Does anyone have any suggestions as to how I should best approach this? I also thought about having a PC interface for voice recognition, and have it then transmit to the STAMP module via bluetooth.

Any and all suggestions are welcome, thanks!

    The VR Stamp is quite small actually.

    It says the VR stamp is a 40 pin DIP.

    THe parallax BOE board doesn't seem to be 20 pins long...

    Am I missing something here?

    No, you're not missing anything. The breadboard on the BOE is indeed small with 2 x 17 strips of contacts.
    There's no reason why you can't get a bit larger breadboard and connect the two with jumper wires and physically
    mount the 2nd breadboard under or over the BOE. It's easy to add additional spacers to the existing ones for the
    BOE on the BoeBot chassis and attach the extra breadboard to a sheet of plastic mounted on the spacers. I'm sure
    you could be very creative.

    Yeah I suppose I could extend the breadboard..it's just a matter of making it look clean =)

    So with the VR stamp module and the BASIC Stamp2 controller, that should be all I need for voice controlled movements of the robot? How would I interface the microphone?

    Also, if anyone has any knowledge//experience on going from microphone-->PC software-->robot for voice recognition, feel free to shed some light. I don't know which method would be most efficient (with a chip like VR or by going with PC).

    For a VR Stamp solution, read the datasheet and manual for a description of how to attach a microphone to the VR Stamp.
    Using a VR Stamp looks like it might be much more complicated than you might want. It may require some programming
    of the VR Stamp which means you'd need a VR Stamp development board. The VR Stamp requires a 3.3V power supply while
    the Parallax Stamp uses 5V. You can use some 1K resistors between the Parallax Stamp and the VR Stamp to protect the
    VR Stamp from the Parallax Stamp's higher voltage.

    Hmm yeah I haven't read up on the VR module really. I just wanted to see what people thought would be the best approach first.

    Basically my intended purpose is to just have basic motor control of the robot with speech commands.

    For example, I just want to simply say "Move Forward" and the robot will move forward. Or "Move Backwards" (turn, stop , etc.)

    If I do indeed need the VR stamp development board, then I may want to try a different method.
