None of them knew you are supposed to reduce the /i/ and/t/. To fully pronounce these sounds will be unusual for the listener, who is expecting a sound more like -adee, instead of itee. Make the /i/ sound like the “uh” or schwa. Make the /t/ sound like a /d/.
Also in these multi-syllabic words, you’ll want to stress the syllable right before the -adee.
Keep up the good work speaking English!
