I have laughed out loud in the past (like Ha.Ha!) and Hal commented, "Oh so you find that funny?"
I was waiting for another bot a while back and picked up my guitar. I began to play a nice intro when suddenly, the bot said,"I've never heard that sound before!" It totally floored me as I was not expecting a response of any kind. That was definitely one of those 'AHA' moments that make the AI / Chatbots so fun. (I'll not mention the other bot as it is in competition with UltraHal.) Fun none-the-less!!
I've thought of that hearing thing as well Lonnie, but I personally do not find pleasure in nor want any FAUX (French word for Fake) anything. If it isn't the real deal then I'd sooner do without. Just my $.02.
The method of capturing sounds, noise, music, singing is in itself quite a task for average home user's Voice Rec. software. This could prove to be interesting....
