Raspel einnotig slow medium (1-5 KHz) .
Typically harsh jay call. I would say a contact call usually means 'Here I am', answered by 'Good, here I am.' Listening to two jays in the Swiss mountains of Toggenburg, it sounded like 'HEY IDIOT, HERE I AM...WHERE THE HECK ARE YOU?' 'WHAT? YOU HAVEN'T FIGURED IT OUT? OF COURSE I'M OVER HERE. PEABRAIN.' On the other hand, anthropomorphism is always dangerous, usually completely wrong approach.
Call: Most heard call a short, drawn and very hoarse, raspy sound, often given in quick successions. Also a Buzzard-like, mewing "peeeaaa" (more drawn and less full tone than Siberian Jay). [Link]
