Camera mic got covered halfway through my graduation speech

First time user here.
I converted the MOV file to MP3 using AnyConverter. Then I imported the audio to Audacity.
If it helps, it sounds like listening to a speech through a glass bubble.
How do I fix this and make it easier to hear what I’m saying?

Here is the audio if it could help. Problems start at about 3 minutes in.

This is as far as I got. The picture is Effect > Equalization. It’s not just muffled. It’s also noisy. The correction starts after a few seconds.

Hi, thanks for helping. Is there anyway to get rid of that fuzzy noise? I played around with the high pass filter and amplified it too. I don’t know if that is the right way to do it. You equalized pretty good, is there a way to delete the noise using the noise removal effect?
