We don't say I /ate/ out/ this/ weekend/, we say
I ay-dout this weekend.
Ate and out are linked, and the t becomes more of a d -
The t on out is stopped, it sounds like ate out, not ate ouT.
In the statement "The meeting is in her office," we contract the word is, meeting's, not meeting is.
We link is, in, and her. The h drops out. it sounds like zinner, meeting-zinner office.
We don't say I/ need/ to/ tell/ you/ about/ it,
we say "I need-duh tell you abou-dit."
Need and to are linked. The d is stopped and the t becomes more of a d. Need-duh. The pure /u/ vowel becomes reduced to vowel schwa /ə/. Need-duh.
About and it are linked. The t becomes more of a d, abou-dit. The final t is stopped, abou-dit, not about iT.
