Time to call upon the vast pool of knowledge of the best tech community on the internet! I'm looking for a program or app that will allow me to place a microphone that will detect key phrases and spit out prerecorded responses. I'm looking to stage a very simple conversation with a "ghost" through a radio. The obvious route is to record everything on a time delay but because the event in question has a variety of variables I'm not entirely comfortable that I can maintain a timeline. Hopefully someone has some experience here and can point me in the right direction. I'm certainly willing to entertain other options though. A wireless remote that will allow me to page through recordings in succession would also work adequately, but it would mean I have to "ask" questions in a precise order. What do we think? Does such an audio detection program exist? Thanks guys! I'm sure you'll knock this one out of the park for me!
