One of the reasons for poor diction is flaccid lips. In this exercise I show you how you can make your lips more active and improve diction.
Every morning I start by saying tongue twisters and / or reading the texts of benchmarks.
And I do it monthly, that is, I learn a dozen tongue twisters and work with them for a month. When these are perfected, I learn new ones, etc.
It's more difficult with rap tracks. First, not all benchmarks appeal to me. Secondly, not every text can be spoken.
Oksimiron, Eminem and Epic Rap Battle of History help me.
Articulatory gymnastics for lips and cheeks
Tongue twisters (there are many, many different collections, depending on the required pronunciation)
Singing (preferably in a voice)
Reading by ear
There are a huge number of exercises for the development of the so-called "speech apparatus". You can study on your own or contact private speech schools, they teach such a subject - stage speech, of which diction is an integral part. Highly recommend. Not only will you improve your diction, but you will also acquire generally correct speech. Well, if there is no opportunity to attend additional classes, then go ahead to the theater libraries of the leading theater universities. There are a lot of textbooks that reveal the "secrets" of good speech.
I will answer as I myself have recovered from stuttering. 1) talk less with those who make fun of you. 2) find a secluded spot and sing. sing songs you like. the secret is simple. when you sing you sing to yourself. but when you say that for others. when for others that is the fear that they will ridicule or not understand. 3) after you start singing without stuttering, say the words. quietly to myself at first. then loudly. 4) visiting a speech therapist will also not be superfluous.
I sincerely wish you victory over the problem!
Read aloud. Speak tongue twisters, in which the emphasis is on those sounds that "sink" in you. In this case, it is advisable to put something on the cheek, for example, a nut.
Progress will be noticeable sooner than you think.
If you want a clear, well-defined and confident diction, then I can advise you to start playing online games. I guarantee that after losing at least 50 hours, you will start shooting with words like Eminem, tens or even thousands of words and the category of "foul language" will fly one after the other and you just shit with the clarity of your diction.
