Can you please tell me the difference between automation and AI automation … Thank you

So I’ve been experimenting with AI voice receptionists, and I just recently put together a working demo. This one can answer calls, handle basic questions, and even book appointments — all while sounding super natural. I recorded a short call so you can hear it in action 👇(attached video) What fascinates me most is how close we’re getting to AI voices that feel human, with pauses, ums, and natural flow.Imagine every small business having this running 24/7, never missing a single lead. So recently I've made this video and posted on my various channels YT, Linkedin, FB, twitter, on Base App 😅, yes! Basically everywhere and many people reached out to me on this, asking about its realness feel, indian voice, also got some projects of it. And ya it really amazing to see how much demand of this simple thing is in the market. So just thought to share it here as my experience. See the video on your own and let me know its feel what do you think about it! Would love to know: 👉 Does this sound “real” to you? 👉 Where do you think voice agents like this could be most useful? Or whatever you think.
