Maybe give her a talk when you're not discussing something important and tell her how hard it is to hear what she's saying and that you're not trying to be mean but you still can't really.

If you do it outside of other discussions, maybe she'll better remember.

That said I feel for you. That stuff can be annoying and I know that feeling of not wanting to be a dick but looking like an asshole.

It’s the same rules as when someone over-estimates your fluency in another language. When I was first learning Spanish, I asked people to slow down all the time because I couldn’t keep up. It seems most people are good at honoring that - at first. But at a certain point, they go back to their normal speed (or volume.) So I had to either constantly ask people to slow down, or just smile and nod through clumps of words that sped by in a blur and hope I interpreted the speaker’s tone correctly.

Oh god I worked with someone like that, a whisperer. When I asked her to speak up, she would make exaggerated mouth movements as if I was a lip-reader. Later on she moved into broadcasting and I was pleased to see (and hear) that they had taught her to use her vocal cords.

Can you politely tell her that you have trouble hearing her often and that she may need to speak up whenever she communicates with you? You can blame it on your own hearing to prevent offense.
