JTT, go back to the "mada meena" and "kagle ogle ay" I mentioned. Using that exercise, work on getting clear vowels and consonants. Relax. Sing/speak on the vowels, to keep your sound open. Don't hammer "k" sounds, don't let all the air leak out on "h" sounds, don't hiss on the "s" don't hang on to nasal "r", "m" or "n" sounds. Don't break words and phrases in the middle (a bad habit in pop singing right now). Have enough breath to carry you through to the end of a word or phrases (this is where learning breath support comes in). Diction IS about the voice. Even if you are asking about speaking, not singing, it all applies.

Maybe you could give me an example of exactly what you think is "blurry" about the presentation you want to sharpen - do you have an accent that is difficult for some people to understand? What exactly is "blurry"?

Sincerely trying to help,

Alice
