I use Magix Audio Studio.

But there is decent freeware audio editing programs out there that could do the trick such as Audacity.

You have to know what you are doing though. You have to know how to use the filters and noise cancelation functions.

Yes, I tried to use audacity, but it didn’t work because I don’t know how the filters work. So I thought it would be easier to generate different files with random options and just listen.

Create a narrow bandpass filter of a few hundred hertz to reject the background then sweep the spectrum for the spot which best raises the voice out of the noise floor, then play with the spread of the bandpass (FWHM) to optimize it for the width of the voice signal.
