Removing vocoder/voice masking?

I took a recording of something that strange I heard on a telephone hold line and could easily make out voices in the music which had vocoder or something on them to mask what was being said. With just a single track is it possible to remove these effects and clear up the voice somehow? Thanks in advance!

Here’s a link to the recording itself:!C81ECLBZ!135iZicXNJ48kK15rxUI6BhaudJ4o3RFClypFbdv5kE.

No it isn’t possible.
If you can find the song on iTunes you may be able to look up the “lyrics”, but I suspect that it is just “vocal sounds” rather than meaningful “words”.
