My and Our, Amr Hlp Needed

I have a question about weak forms in G.A.
If you go to search for the word "MY" at M-W.com you will see two different pronunciations, one is "mai" and the other one is "m&",
I understand that the second one is the weak form, what troubles me is that I didn't know that americans pronounce this word in such a way when unstressed.

Also, if you look up "OUR" you will encounter two pronunciations: "är" and "au(-&)r".
I didn't know that the first one was common in america, and I always thought that this word was pronounced "&r" when unstressed, and if that's the case ,
why don't they show the unstressed pronunciation?,
just like they show "y&r" for YOUR".

I don't understand, help, please

<< didn't know that the first one was common in america,>>

I'm an American, and I pretty much exclusively pronounce "our" as [Ar\].

<<and I always thought that this word was pronounced "&r" when unstressed, and if that's the case, why don't they show the unstressed pronunciation?,>>

I think I would always pronounce "our" as [Ar\], even in unstressed position. I think one factor preventing reduction of unstressed "our" to [@`] might be that it would lead to confusion with "her".

<<I understand that the second one is the weak form, what troubles me is that I didn't know that americans pronounce this word in such a way when unstressed. >>

Some people do but not everyone. The unstressed /m@/ "muh" is relatively uncommon at least here in California. If it is used here it may be only in a jocular fashion.

<<I think I would always pronounce "our" as [Ar\], even in unstressed position. I think one factor preventing reduction of unstressed "our" to [@`] might be that it would lead to confusion with "her".>>

Yeah I don't have [@r\] for "our." It's usually [Ar\].

<<Some people do but not everyone. The unstressed /m@/ "muh" is relatively uncommon at least here in California. If it is used here it may be only in a jocular fashion.>>

The same applies here in Massachusetts - I, and everybody I know, pronounce unstressed "my" as [maI]. Unstressed [m@] would be perceived as a strange or extra-regional feature here.

so guys, one last question, how do you pronounce OURS?
A:R or AURS.

Thanks for your help,
love this forum

Unstressed and normally, it's arrs. But if I am trying to stress the word, I'll pronounce it the same way as I do "hours" -- ow-ers.

>>Unstressed and normally, it's arrs.<<

That's how I pronounce arse.

Oops, you're right. I would actually pronounce "ours" as arrz, not arrs.
