In my experience, a lot of Americans, on many occasions, don't make the standard /t/ sound in words like "wanted," "twenty," "accidentally," "presented," "interview" etc. I feel like when they don't make the /t/ sound in words of that type, many of them kind of go by the /t/, or probably make a sound that's similar to the flap /d/ sound.
I looked up videos on this occasion in American English on Youtube. In all of the videos I saw, the instructors say the /t/ is completely dropped when that happens, but when I hear Americans, mostly it doesn't sound like they completely ignore that consonant. It feels more like they go by it somehow or make a sound similar to the flap /d/ as I said. When I talk also, when I completely drop the /t/ in those kind of words, it sounds kind of off to me. I don't know if it sounds uneducated or totally wrong if I completely drop the /t/. I actually remember noticing that some Americans probably completely dropped the /t/ on some videos involving Americans that I saw before, but those moments were rare. It might depend on the region and education maybe?
This is one of the videos on this topic. What do you think? Do you think Americans can completely ignore the /t/ sound in words like, "wanted"? Do you think it is wrong? What kind of sound should I make if I want to go by the /t/ sound like Americans? This is pretty important for me since I have been learning American English for some time.
