Greetings Forum, I would like to incorporate an ADC Electret to assist with the windows 7 VR for my talking head FRED. We know that Windows 7 VR is really only good for one person, so it would be nice to differentiate 2 different voices and the robot responds accordingly. " Please Guest of Master (DJ Sures) may i have your name and the purpose of your visit" ...or some such response! This would mean perhaps using ReadADC control and responding OR (@Rich ) creating a script to "analyze" a different frequency/waveform. We all know that a females voice has a higher frequency typically and therefore would be easier to "differentiate" two or more voices! This script is not ment to allow VR of different people but to merely "know" that there are two people saying "something".......I believe the EZ-Board has 8 bit ADC which would be enough resolution to work with....0- 255. its the waveform/frequency I am not sure about.
