I'm new here and have a question. Let's say that I want to build a system that will allow me to speak directly to a robot and have it reply by playing an existing sound file. I don't want to speak into a tablet or headset, but directly to the robot. There will be no servos running, no whirring or clacking of other components, so there will be no background noise. Does the EZ-B v4 allow for a microphone input that would allow me to do this? If not, is there another piece of hardware you can think of, maybe even one that is self-contained, that would for this function?
