I have some isolated audio of some dialogue, and there is a slightly robotic sound to the person speaking that I'm looking to get rid of, but no matter what I try I can't seem to get rid of it. Here's a sample. (You might need to listen with headphones to be able to hear it. The effect is pretty subtle.)
I have tried editing it out using Audacity (and I tried MANY different effects), AI voice restoration tools, I have spent hours googling and asking around but so far nothing has worked.
Is there any way at all to make these vocals sound more natural through post-processing?
(PS I know there are two similar questions to mine on here, but the samples in both are lost thus I cannot conclude that the answers given in them apply to my case.)
