It's been several days and nobody has responded, so I will attempt to reply.
Not really sure what you mean by scrambled voice. Are you speaking of digital voice protocols such as P25, D-Star, DMR?
There are no "Plug Ins" like SDR# uses for various features such as decoding digital voice in SDR Console.
What frequency does this 'scrambled voice' operate on?
A screen shot posted would be VERY helpful!

If scrambled voice is simply spectrum inverted you should be able to switch to the opposite sideband and move the appropriate direction and demodulate it. Nothing does this for you automatically, though.

Suppose you are on USB. Then the spectrum is inverted. You tune up 3 kHz and switch to LSB. It should be readable with limited retuning.
