I pronounce your and you're differently
What's the difference in pronunciation?
I just say them slightly differently.
It's reasonable to pronounce words differently if you think it'll help make what you say more understandable. It would be confusing if you didn't make yourself clear.
The difference is huge, and very important.  Maybe there are others who do the same.
It is good to be clear on what you say.  Just make sure that others are on the same page as you.
