Method proven in practice: we perform the exercise "Horse" (click the tongue). During this exercise, you will feel how the tongue becomes wide and "sticks" to the hard palate. This is what we need. After that we perform the "Mushroom" exercise. It comes from "The Horse". We begin to perform this exercise very slowly, and at the moment when the tongue begins to rest against the hard palate with its maximum area, we leave it there. Then we inhale and direct the air stream to the tip of the tongue, pronouncing the sound T. You can also put the sound P from the sound S. To hiss, just not as usual, but by inhaling and exhaling a large portion of air, directing it to the tip of the tongue (it should vibrate ).
Speech therapists, when working with people with rotacisms (defects in the pronunciation of this unfortunate sound), usually use such an algorithm (if you don't want to contact a specialist, you can try it yourself, but keep in mind that achieving a result will require regular training and enormous volitional efforts): open your mouth wider, you begin to pronounce a long sound "Z" and at this time with your finger (in the original a special probe is used, but the effect, in fact, does not change) make oscillatory movements across the tongue. This causes vibration of the tip of the tongue, the absence of which, as a rule, leads to a violation of the pronunciation of "p". Repeat such exercises daily, gradually ensuring that the vibration arises reflexively, without external stimulation, combine them with repeated repetition of words, learning tongue twisters, poems and short texts saturated with this sound (you can find a huge amount on the network) and believe that patience and labor will grind everything! Articulating gymnastics (the list of exercises for this sound is also easy to find) will be of great help, by the way.
Don't pronounce the letter "r" and joy becomes disgusting.
At a young age, you can still get rid of without effort - to go to a speech therapist.
In adulthood, there are a couple of uncomfortable schemes:
Exercises, with a long and thorough pronunciation of words, tongue twisters
If you are an announcer or read a speech, then in the text you can get rid of words containing this unpleasant 18th letter - pick up synonyms. (which I do)
Sometimes the problem lies in the language itself - it may not reach the sky. Then a small incision is made between the tongue and the "bottom" of the mouth. But then for getting used to and pronouncing "p" you will need to do all the same exercises.
In adulthood, it is very difficult to correct burriness, and sometimes it is completely impossible. However, if you don't burst much or you just don't like your p, you can do the exercises.
Cluck your tongue. Like when children play the sound of a horse running. (probably, the position of the tongue at the moment will tell you how it should be correctly positioned when pronouncing the sound "p", and repeating the exercise will teach the tongue to be placed correctly)
Read tongue twisters with this sound. Growl a lot.
As a child, a speech therapist gave an exercise where you just had to inflate a balloon. I honestly have no idea why. Probably, this is also connected with correct articulation.
only with long training sessions you will achieve something. I still do not always pronounce due to physiological characteristics. but in general, do you need it? does it bring such great discomfort? if not, burr is not a vice, there is nothing wrong with that. and if you want to become an announcer / presenter / etc. and you need a clear speech, then type yourself a list of words with this sound and repeat like Our Father several times a day.
