Remove horrible screeching noise

I have an audio file of someone speaking which seems to have a bit of a screeching noise (similar to when removing vocals) when they talk, especially when saying an S. Is there any way to fix this?

You can post 10 second stereo (two blue sound waves) or 20 second mono clip (one blue sound wave) of the work here on the forum. Export using WAV (Microsoft) format please. Scroll down from a forum window > Upload Attachment.

As a fuzzy, but almost universal rule, we can’t take out effects or processing in post production.

What’s the goal? Goals are good. Are you hoping we’re going to rescue your work well enough for a podcast? If you can’t always understand what’s being said, that’s usually the end of the world.
