how to pronounce "higher" and "hire", "pattern" "turn"

hey! finally we have a moderator who can delete unsavory messages from this forum! Who are you, moderator? I commend you.

Caesar, you have some very interesting remarks. are you a professor?

I pronounce them the same.

No, Octo, I am not a professor. Besides, my native tongue is Spanish (I am from Costa Rica), but most US people I have talked to believe that I have no accent whatsoever.

Cheers!
