I searched the Net for any support of the idea that a Spanish "j" could sound like a "p," and found nothing. However, I did find something that might help to understand the prounciation. I saw it said that the "j" is sounded out like the "h" in "hot" but "raspier." This latter point I did not priorly know. And I am thinking now it must be an intentionally induced harsh raspiness which could cause a "p" sound or effect to occur. And I would think that "julio" and "junio" should sound similar.
The j sound, [x]: It is an unvoiced, dorsal fricative. Unvoiced indicates that it is formed without use of the vocal cords, dorsal refers to the location in the mouth (back of the tongue), and fricative describes the interruption of the flow of air. Depending on what country you are in, or even the region of the country, this can sound more or less raspy, forceful or guttural in Spanish. The University of Iowa has a great little website with lots of phonetics information for multiple languages, if you are interested.
In Spanish, "referee" means "árbitro", but in some sports, there are also "jueces". For example, in football/soccer, there are a main referee, called "árbitro", and assistant referees, called "jueces de línea".
But, although Duolingo says that "referees" is a correct translation, if you answer like that, it marks wrong!
The situation is known as a short coming. Apparently, the peeps that work up the lists are different from the ones that create sentences and they don't talk to each other. So, if you feel adventurous you can use the other words in the lists if applicable then when you error out you can report it as a sentence which should have been accepted. It may then get fixed in a distant future. Maybe.
It is just something you have to remember. If it was juezes it would sound weird in spanish. Changing it to jueces maintains the correct pronunciation. English is known for having many words that don't make sense with pronunciation or spelling. That is why it is very hard to learn English in the beginning for some.
Thanks for this explanation. I award you a lingot! The z in Spanish sounds like an s in English. A c followed by an i or an e in English is soft (in other words it sounds just like an s in English and apparently in Spanish too.) So in Spanish it is just a spelling change not a sound change.
In American English we usually mean "judge" as in courtroom/jury. But it is also used for judging sports, like in the Olympics. Rarely would someone call a referee (or umpire) a judge. Yet a referee does make a judgment call on a play (in sports).
I'm sure that was just clear as mud. :)
In English, you would not call a referee in a game of soccer (football) a judge.
You would not call a member of a panel of judges in Olympic diving or gymnastics a referee.
You would call the official who sits in a high chair to watch a game of tennis an umpire. The people who crouch down next to the lines of the court who decide whether the ball is in or out are linespeople or line judges.
