I do that so much. I can read languages on the internet... but it will take me a minute to realize which language it is, since they all sound pretty much (except french and Asian languages) the same and MOST of them have the same symbols... XD
It's not a robot. It's a real person. That person, however, may not be speaking in sentences... they may just have that person say a bunch of random words, and then they use computers to make sentences with those words... so maybe that's why that sounds like that?
