Today I finally found some evidence for the "right"* way to pronounce "Joralemon St." in downtown brooklyn:
says it's /dʒər'æləmən/, not my (and others') guess of /ˌdʒorə'lɛmən/. Likewise
And it has to be, to make the amphibrachs work out in the poem here:
"Schermerhorn", though... Everyone seems to agree that the main trick is that the ch gives a hard /k/, but there's quibbling over the vowel. I'm most fond of what I hear train operators say, unmistakably, as they pull into the Hoyt-Schermerhorn stop: /'skɪməˌhɔn/, something like "Skimmahawn" if I had to spell it out.

Aw damn I just heard "Shimmahawn" on the train on the way home just now. WHAT AM I SUPPOSED TO SAY YOU GUYS.
