I want to make a robot that does the following when told just "1" of the commands next to the action:
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.
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...
how about if we simplify the speech?
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
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
but what should the code be?
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.
