I've been able to almost completely replicate this effect simply by formant shifting several octaves down and using LFO-modulated ring mod in ableton live. it's almost disappointingly simple.
it is definitely not subliminal, historical, or a secret message
It doesn't sound like a Scottish accent at all though, it sounds more like the type of English accent from old broadcasts. And I'm sure they said the old piece of gear they travelled to pick up is a one second sample on Cold Earth.
