    The article was very interesting. Actually, I never thought about  the way I held certain ending of words in a sentence as having a specific name for it. I know that sometimes when I say a statement, I will raise my voice tone at the end of the sentence because I am looking for a response from someone. For instance, "I’m going to wear this dress^."  Crystal states that studies have shown that women used it twice as much as men and teenagers used it ten times more often than people did over 20 (249). This is not surprising. Perhaps, women use it more than men do because we love to express ourselves in different ways, and communicate with one another.
In expressing ourselves, we begin to put certain emphasis on particular words to give a signal for importance. For example, when I teach, I have a habit of sounding off  the ending letters of some words in  higher pitch  in a sentence. As I tell my students, I do this to only let them know that I am saying something I want them know or that they should have already known, and I am just trying to recall their memory. On the other hand, I believe that teenagers use high rise intonation because they are always searching for approval from their peers.   Teenagers do this because they do want to stand to be so different.  For instance,  a teenager might say, "We are going to the party^. "  Although he is making a statement, he is still searching for a response.  He does not want to appear as being "not cool" even though he does not really want to go to the party.

T    he next time you say something or listen to someone, pay closer attention about how you say it or the other person says it because you might be using a high rise intonation^.

Note: ^ stands from high pitch at the ending of the word
