I enjoy this is site. I see it uses "no-name-spell" for phonetics. (I call it this because it has no name as far as I can find out). That notation is useful because it's English friendly with no special symbols. Truespel is as well. It's indicated by a tilde(~). See below



As I hear it spoken in truespel notation it's ~pairuputtetik
~pair as in "pair"
~up as in "up"
~ut as in "ut" etc.
Note thet stress is first syllable or after a double consonant.
