Prosody includes Junk-sure to be missed by a non native speaker.
Besides changes in pitch (inflection), we tend to hit certain syllables and words in sentence with more intensity than others.
For example in the three syllable word, "banana," which syllable is stressed? It has to be the second (baNAna) or the word is almost unrecognizable.
Juncture is the fourth element of Prosody. This refers to a short, almost imperceptible pause between words in a sentence. If you think of a "white house" and then say the words, you will put a slight pause between the words. But if you remember that the President lives in the "White House," and say those words, you may note that that pause is missing.
These minute pauses would probably be missed by a non native speaker of English, yet for the adult, as you can see from the examples above, they can actually change the meaning of a sentence.
