My IPA font isn't working at the moment. Sorry.
Let's try it this way.
In North American English, the vowel in
got isn't pronounced [o], as in
hope. It's pronounced [a] as in
father. Like this, g[a]t, and it rhymes with "hot".
This is how
got is pronounced in your example sentence,
Ex: I g[a]'[D]uh meeting tomorrow.
Hopefully someone will come along with an IPA version.
All the best.
