you refer to the website in lycaeum? is a mistery I'm searching everywhere but I don't know what is, at the beginning I tought was Welsh but then I realized they were anagrams, that's all I understood, is such a mistery!
Paralingua is an imaginary nonsense language used at the Lycaeum website.
It's not language at all, it's either some sort of game, or else a hoax. Detailed technical analysis of its statistics can be found at:

It works roughly like this:
1. Upon requesting a page by search term, it hashes the term to seed a random number generator which then creates random word-like strings. This seeding ensures you get the same page each time for the same search term. Here's some proof it's random: it will *always* find a page for any search term, no matter *what* junk you bang out on the keyboard e.g. here is page "about" a previous editor of this question!

2. The "translator" actually just finds nonsense anagrams. They aren't really "translations", in fact once again it will accept any old junk within certain length limits, and offer the same "translation" no matter how you scramble those letters, e.g.
http://www.lycaeum.org/mv/anagrams/PARATRANSLATE.cgi?phrase=Ni+sohee+sed+che
and
http://www.lycaeum.org/mv/anagrams/PARATRANSLATE.cgi?phrase=cdeeeehhinoss
give exact same "translation".
By the way, the illustrations are copies of diagrams on alchemy deep-linked from another site (and consequently, some of them are broken), while non-Roman letters are copies of pages from the mysterious Voynich manuscript:

however it is not otherwise related to Voynich.
Paralinguistics refers to the nonverbal aspects of communication, such as intonation, pitch, and facial expressions, that help convey meaning alongside spoken language. It plays a significant role in understanding the speaker's emotions, attitudes, and intentions.
