About insteresting
About interesting, it sounds like /interis/ (/e/upside). It should be /tri/. It seems you separated t and r to /teri/. The first e is a silent one.
Another thing is you can always do BE or AE, but better be consistent, not mixed up. Otherwise, later on, you have to come back to straighten them all. I think since we are in US, we might follow AE.
Just my 2cents. Maybe I am too wordy.
