Help Siri and keyboard can't hear me

I've read several discussions on this problem. This is what I've found: I did a reset to the settings, which someone recommended. This shuts Siri off. The Voice Control can hear me. Once I turn Siri back on, I can not be heard. Shut it off, Voice Control hears me....

I've done everything short of a system restore.

I also have an ipad and Siri works with no problems.

Can anyone help?

Maybe I'll have to head to a genius bar.
