Is there a way to shut off the comic relief voices in Oddworld: New 'n' Tasty?

I'm playing Oddworld: New 'n' Tasty on Steam. It's taken some liberties over the original game, some good and some not so much. There's one that's grating for me: the Sligs and Mudokons all have some idle comic relief commentary, and they'll mutter it constantly, stuff like:

Slig: Ugh, when's lunch?
Slig: Maybe I'll even get paid this month.
Mudokon: Another day in the office...
Mudokon: Employee of the month! Now I even have my own brush!

In the original, everyone was silent and there was a really oppressive atmosphere to Rupture Farms. Suffice to say this commentary is really atmosphere-breaking for me and is making it hard to fully enjoy the game.

Is there a way to shut off the commentary, and only the commentary?

The volume control for voices also controls gamespeak and cues like a Slig saying "what!?", and subtitles don't display these messages, so that in itself doesn't solve much.
