Thanks for all the responses.

From them I read:
First priority is to avoid speaking the www.
Second most used version is repeating 3 times the letter w (with your local variation of how to pronounce it - doubleyew, doubleya, dubya, ...).


Mary, Volkswagen (only one o in it) is not pronounced Volksvagon. It is pronounced Vau-We or Volkswagen ;-).

The letter V is sometimes pronounced like a hard F (as in Volk or Volkswagen or Vau) and sometimes soft like a W (as in Vase - the thing you put flowers in).
But the letter W is always pronounced soft.

It is hard to describe the pronunciation with written English, as English pronunciation is even less consistent (example: the letter group ough: though, thought, through, tough, ... or ea: read/read/early ... or new/sew or ...) with the written letters than in German.
