You might ask here if you are in doubt.
For instance Salicional is pronounced Sal-ish-un-al with the stress on the second syllable. Slurred all together of course.
And Diapason is Di-a-pay-zun accent on third syllable. Di as in die, a like the a in at.
These examples might not work without some explaining of how to pronounce each syllable as I've done for Diapason.
