I'd pronounce those the same (western US accent), but it can vary. Check out the caught/cot merger, for example: https://en.wikipedia.org/wiki/Cot%E2%80%93caught_merger

They are for me. Exactly the same pronunciation and emphasis. Maybe there are some dialects of English where they are not pronounced the same.

They're really quite close, both pairs of them. But the emphasis isn't quite the same as most people speak it.

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.

Yes, they're homophones.
