"I don't"
I pronounced "I don't" as [ao~] whenever it's not a response. So for instance
"I don't have one" [ao~ hE{:v wV:~]
"Do you have one?" "I don't" [aI: do~?].
Does anyone have this contrast between "I don't" in a sentence and "I don't" as a response.
I don't really have such a contrast; rather, I just very frequently lose /d/ in "don't", "doesn't", and "didn't" in everyday speech when following a personal pronoun ending in a vowel or "why" in general. Note that such is a very common feature in everyday speech in North American English today, particularly in the speech of younger people and in the case "I don't".
<<I don't really>>
What a coincidence. You started your first sentence with "I don't".
<<"don't", "doesn't", and "didn't">>
What about "do", "did" and "does"? Do you lose /d/ in those also?
>><<"don't", "doesn't", and "didn't">>
What about "do", "did" and "does"? Do you lose /d/ in those also?<<
No, I always have [d] or [4] in these for /d/, which is never lost.
<<[ao~] >> That sounds like a nasalized "ow!" to me.
I pronounce "I don't" as [a: oU~]. It keeps its two syllables while losing the /d/. Do you others actually pronounce "I don't" as one syllable when it loses the /d/?
If I recall correctly, Josh Lalonde is from Canada.
For me "I don't" when somewhat stressed in everyday speech is disyllabic, being ["a~:.o~?], when not followed by a vowel, or ["a~:.o~n], when followed by a vowel. When unstressed in everyday speech it is monosyllabic, being ["a~:o_^~?], when not followed by a vowel, or ["a~:o_^~n], when followed by a vowel. When very unstressed in everyday speech it may also be ["a~:o_^~].
<<I don't [ao~]
I didn't [AI I:~?]>>
What about "he doesn't"? I have [hi Vz=n], or [i Vz=n].
