Is there a tool to learn to pronounce aviation jargon accurately? So I've been reading technical aviation books and I come across a lot words I want to learn to say correctly but unlike simple words which I just look up in an audio Oxford dictionary I can't think of where online I can find audio pronunciations of aviation words. Any suggestions?
With the exception of abbreviations (like FSDO, pronounced fizz dough) there's not much "jargon" in aviation that's not a standard word in whatever language you're speaking. Words like "dihedral", "anhedral", "aileron", etc. should certainly show up in a dictionary.

The abbreviations are "tribal knowledge" the same way they are in any other field (e.g. SCSI, SATA, IMAP in the tech field). I'm not aware of any authoritative compendium of pronunciations.
