Michio Kaku telling himself to wake up

In a theoretical physicist talk, Michio Kaku talked about the different types of civilizations that could possibly exist out in outer space and at the end of the speech he said thank you, but in reverse it was "Wake up!" pretty firmly lol.

Most of the talk in reverse was gibberish or in another language. There is some english but hard to differentiate. I'll try to find more later.

Here is a perfect example of reverse speech:
