This question isn't answered here:
- Differentiate between past and present just by pronunciation when word is followed by d- or similiar sound
That question asks about what happens when the following word begins with a consonant in general. This one is asking about the various possibilities for an intervocalic tap if a following word is an unstressed function word beginning with /t/. It's also asking whether there's any possibility for regressive assimilation here.
I read this in American accent book. I quote the text exactly how it is written in the book:
The suffix -ed is not pronounced precisely when it is linked to another consonant. For example, mailed the sounds very much like mail the in the following sentences:
- I already mailed the letter.
- I will mail the letter.
The suffix -ed is not heard at all when it is linked to /t/ or /d/. For example talked to sounds identical to talk to in the following sentences:
- I talked to her yesterday.
- I talk to her every day.
Okay but then my question is, how do Americans distinguish between these two sentences:
- I try to call you.
- I tried to call you.
In the first sentence the /t/ will be realised by a voiced tap because it occurs between two vowels. In the second will we get a regular [t] and then a voiced tap? Will we get a double tap or a double length tap? Or will we just get a single tap? Or maybe here we will just get two regular /t/s?
Do native speakers differentiate between "I tried to call you" and "I try to call you" from the context?
