some of the words sounded like a foreign language by Talia

Yesterday I went on youtube and I watched a video and some of the words sounded like a foreign language. But when I showed my mum the clip she said it was all English. But it couldn't of sounded English so then I went to lay on my bed because I was losing my marbles. About an hour later, I got up and watched the clip again but when I heard the words they were different instead of the clip being a song it was somebody talking to me and it was weird because they knew my name. I was puzzled what is going on with this computer.
