Does the tongue tip vibrate when speaking in Spanish? Or does other parts of the tongue also vibrate? .

ekalina Maybe someone in the class knows it, but he doesn’t, because what he said about how to vibrato is all wrong, but the description of his classmates is correct. There is always a D sound when saying arra. It is not a problem with the tongue, but because lz has not mastered the correct strength of the muscle groups and cannot control the strength well. The big tongue vibrato must be the root of the tongue, not the tip of the tongue. What ekalina said is definitely the supervisor's guess. The problem of d stops when lz has been practicing for a period of time. d is a stage that most beginners must go through when making vibrato, and it is not a method problem. ekalina, do you have the guts to stand up and tell me if my guess is right? Come forward! ! ! ! ! ! ! ! ! ! ! ! ! ! !
