Ok, I am totally stumped by this... "So each person probably has to make their own, what we call <XX> - meaning their own kind of calculation""
The <XX> sounds like "hedge bah," with the first consonant being an uvular fricative. I've been googling all the Hewbrewesque spelling variations I can think of and I'm drawing a blank. Trying to google a word with the meaning "meaning" is proving very tough as well.
I appreciate this is an impossible ask, but if anyone has any clue at all, we'd appreciate it!
I'm not sure if she could give me the audio - confidentiality of interviewee I think..
