English is troublesome, that is the reason for books like the "Cambridge English Pronouncing Dictionary," now in its 16th edition.
The current edition also covers American pronunciations- yes, they can be different. I don't know about Australian, but they could be topsy-turvy.
As referenced by Masato, the BBC Dictionary also is good (Oxford Press).

According to the Karpeles Manuscript Library Museum, the pronunciation is KARP e les.

German is easier, unless you delve into low German. Then all bets are off.
