I want to make a robot that does the following when told just "1" of the commands next to the action:

• (Go Forward 1') = ("ONE!" || "MOVE!" || "GO!" || "UP!" || "FRONT!")
• (TURN In Place CLOCKWISE 90^o) = ("TWO!" || "TURN!")

Also I only have 2 mics & 4 op-amps, so this project has to be implemented throw software only...

Do you know how to code some speech recognition code for a computer?
If so you can try to port it to Arduino but I dont think you have enought ram or processing power for that.

[Reply #2 on:]

You can't do it with just a mike & op amp.
Not enough memory or processing power.

how about if we simplify the speech?
like this:
Forwards = "ONE!" + (Pause > 3seconds)
Backwards = "ONE!_ONE!" + (Pause > 3seconds)

also I want to make sure you 2 read the part where i said that i'm going to use only 2 words total to control the Arduino...

also I have an Arduino mega 1280...

No it can't be done.

The best you can hope for is some sort of sound level trigger, sound = trigger1, sound pause sound = trigger2

[Reply #6 on:]

that is kinda what i was saying:
Sound of lengthX, then ~0.3_second pause, thenSound of lengthX, then 3_second pause = trigger1
Sound of lengthX, then 3_second pause = trigger2

[Reply #7 on:]

but what should the code be?

[Reply #8 on:]

That should be possible but could result in some false positives. Also, you could implement pitch detection with an FFT and then sing to it (if you can reproduce a note)

A bit like this:-

Sparkfun.com (down right now) has a speech recognition device - can't recall how it's interfaced- that is all off board.  Worth noting.
