Getting rid of some echo on my audio

Hi guys,

I’ve filmed something and there seem to be a slight echo “effect” on the audio that I would like to get rid of.
I’m quite new to Audacity and would love someone’s help on how to do that.
(if you can point me to a YouTube clip this would also be great.

Thank you

Since we can’t fix echo, let’s assume it’s not. Post a sample of the work on the forum.
