HELP - Need to remove repeated voice from a interview video

Hi,

As stated in the subject, i have a interview video where the person's voice is echoing in a way that her words are repeating again after a second she speaks. 

Attached a sample audio file.

Request if someone can help me out with removing the echo in the audio. As im new to this editing, request to share the perfect settings which you used to clean the echo.

Thanking in advance
