No, you don't sound like a native AmE speaker to me either. In the first few words, "the" sounds like "de", "speaker" sounds like "spicker" and "speak" sounds like "spick". The phrasing is just a little off in a couple of places. I agree that it sounds slow and, to me, it seems like that's because you're struggling a bit with pronunciation. If I had to guess, I would say you're either from an Asian (Oriental) country - Korea, Japan, Taiwan maybe, or just possibly from Germany, Austria, Switzerland, or somewhere in that area. I would say that English is not your native language but that you've spent much of your life in an English-speaking country, just not lost all of your accent.
We don't have to be native AmE speakers ourselves in order to have an opinion on whether you sound like one.
