Something I was wondering about this morning: native English speakers, do you pronounce initial [wh] and initial [w] differently? I.e., is there a difference in the way you pronounce 'which' and 'witch' or 'whether' and 'weather'?

@joyce For " weather" and " whether" I do something different with my tongue. Don't know whether it makes a difference to the sound. For "what?" I puff more air out between my lips than I would for " well" but again, it may not be an audible difference.
I'm Australian, more specifically from Adelaide. There are distinct differences in pronunciation in different parts of Australia.
