Look Dear, they're not playing our song!
That is what prosody is, a melody and all languages have their own particular song.
I'm reminded of the one time I left the USA, to visit Japan. I stood on the Ginza in a state of intense culture shock, as people dressed in strange clothes drove on the wrong side of the street, ate pink and white oddly shaped foods and read signs from up to down instead of left to right.
To regain my composure, I did what any true American would do…I went to see a John Wayne movie (dubbed, I later learned, in Japanese). Not understanding the currency, I believe I paid $30 for the movie, but that is another story. The real surprise came when John Wayne, in boots and chattels, came out and hissed in chopped syllables, "Oh hai yo go zaee masu." I was totally destroyed.
No more, I am sure, than a citizen from Japan would be at hearing Toshiro Mifune (my favorite Japanese actor) speak (dubbed) in a drawling American tone.
We have learned to expect a specific melody or prosody from a speaker of a specific language.
