Lingua-foyda ack-er-on-sis (you could also get away with Lingua-fohda I think).
Inter-nee-si-vus (again I think you could also get away with inter-nes-i-vus)
I get that it's one thing to type a word and another to say it, particularly unusual ones like this. I pronounced Giger as guy-ger forever until I heard it pronounced properly on making-of docos as ghee-ger (to rhyme with eager). And even then I had trouble getting my head around the proper pronunciation.
