I've had success getting EZB to perform speech recognition on my voice and even the voices of my grandkids....BUT
I'm trying to get one EZB to recognize the TTS voice of another EZB and have not been successful, i.e. robot to robot verbal conversations
I tried different Windows voices and changing speed and emphasis with no success. Even the Microsoft recommended 3rd party voices didn't work.
I tried going through the laborious Windows speech training program where you have to say dozens of sentences and had problems training it to recognize an EZB voice
I even tried recording my own voice for playback and that wasn't recognized either by EZB speeech recognition
