What is the pronunciation of 'cause?

[Asgarpour]

Hi, guys.
As you know, 'cause is the colloquial form of because.
According to the website oxforddictionaries.com, the pronunciation of because and cause is /bēˈkəz/ and /kôz/ in order:

because: http://www.oxforddictionaries.com/definition/american_english/because
cause: http://www.oxforddictionaries.com/definition/american_english/cause

Now, I do not know if the pronunciation of 'cause is /kôz/ or /kəz/!
Please help me.
Thanks in advance.

I would express it as /kʌz/. I am not familiar with the central symbol in /kôz/. In extremely rapid speech, speakers of AmE might shade towards /kəz/.

I don't do phonetic symbols but in BrE, it's "coz". It rhymes with "was".

cause: http://www.oxforddictionaries.com/definition/american_english/cause

The abbreviation 'cause is pronounced exactly like the second syllable of the word because i.e. /bēˈkəz/.

The pronunciation /kôz/ is of the different word cause, which rhymes with pause.
