I'm having a hard time figuring out the right placement and motions of the tongue when making this consonant. I watched a few videos on this topic. People say that in order to make the sound you don't want to be touching the roof of your mouth too much but you have to lightly bounce the tip of your tongue against the roof of the mouth. I have no idea how to do this. I tried doing it and I either touch the roof of the mouth too hardly and it sounds heavy and unclear or in effort to touch lightly, I end up accidentally pulling my tongue away and it doesn't even reach the place that it should. I would be really grateful for an explanation of what is that that tongue is doing when you make this sound. Thank you for the answers in advance!
It is similar to the "d" sound, but the main difference is that you lift your tongue from the bottom of the mouth and touch your top teeth near the top.
While your tongue is touching your teeth, you push out a very small puff of air. This air will separate your tongue from your teeth and it will help make that "t" sound.
The "d" sound is similar in the puff of air, but it does not have the tongue touching the top teeth.
