Which service is calling customers like a fake call center?

Question

Marketing

I received a call where the operator, against the background of the real noise of the KC, began to offer me some kind of service. After a few remarks, I realized that the operator is not real, but a robot (bot). The bot very succinctly adjusted to my answers, asking the following according to the script.
Can you please tell me what kind of service(s) this is?
The standard services that I managed to google are just audio clips that turn on.

Answer 1

Standard and no. They are being programmed

Answer 2

Of those that can stream speech recognition and cost dialogue infobot.pro, smartcalls.io and ringing dog. The rest mainly work through keystrokes (there are many of them, google "robot calls"). Cool robots with complex synthesis, with the ability to understand the context, etc. are created to order at a high cost.
