I am 99% sure Americans quite often flap the /d/ sound which comes right after /r/ in the phrases "Where did", "Where do", "Where don't" and "Where does" (I am talking about the initial /d/'s), and I always flap the /d/ in those phrases; but now I somehow couldn't be completely sure that Americans do that. Do Americans do that?
I know that when "did" follows a vowel, the first /d/ can be pronounced as a flap sound. For example in "Who did you go with". But it is wrong to flap it if you say "Yes, I did" since "did" is stressed there. So, I am asking if I can flap the first /d/ of "did" when I say "Where did" as well. Also I am asking about the other phrases I gave which start with "Where".
Example sentence:
"Where did she go?"
I would always flap the first /d/ of "did" in this sentence.
Another example:
"Where does she go?"
I also would always flap the /d/ in this sentence.
One more example:
"Where do you live?"
I would always flap the /d/ here as well.
And the final example:
"Where don't you want to go?"
I would flap it here too.
Update:
You can see what I mean by the "flap sound” in this YouTube video, or in this YouTube video, and at this ELL question (please look at Peter Shor's comments who is quite knowledgeable in this topic).
