As a speaker of fairly standard British English, I would say they are homophones; I tried but couldn't find any natural way in which I could pronounce them differently.

dictionary.com shows both with the same IPA: \wik\ and \pis\.

I think they're identical.

I’m sure, in many accents, that they are. Definitely not the same in Australian Strine.

As an American, I knew about Straya but this is the first I've heard of Strine. Or should I say Murican :)

They're identical in Australian English.

Which one?

They are identical. I think he was making a distinction between {week, weak} on one hand and {wick} on the other (but I was also initially confused by the way he put it). This is a big hurdle for native Spanish speakers as well, because i in Spanish is always pronounced as "ee". There seem to be a lot of embarrassing word pairs around these vowels; sheet, beach, etc.

Yeah what I meant is that it just increases the possibilities of awkwardness. Piss of cake, piss process, etc.
