Question on the voiceovers in Nier raids

I refer to the alarum voice at Copied Factory, the operator in Puppet's Bunker, and the announcer at the Tower. What are those voice overs saying because I could not make out what is being spoken?

As far as I know it's not actually anything intelligible.

I heard a rumour that it was actually real life station announcements from the Tokyo subway, but deliberately distorted to hide that. Whether that is true or not is anyone's guess, but SE has done something like that before (back in FFXIII in the Purge train at the start the dot matrix display in the background scrolls real life Tokyo rail system station names but rendered in Coccoon script).

The language in Nier is a "made up" one, just a jumble of Japanese, English, and some European words/sounds.
The Nier OST "Song of the Ancients" tracks use a lot of that "language".
For example:

Kuwata tsunowo vralai

Kwondzuvai undovartsu wronduwail
Tjortetei jeki liago

Jiunmata ivelischpfuli
Neftyoma sorepiyamei
Schijiyako alefni fatalliliya

Popola (sung simultaneously)

Just ignore them. Nothing they do makes any sense.
