Is the English Language Changing?

[Elipsys]

I have observed many people, including news commentators, that are changing the way some words are pronounced. Important, becomes impor-aant; mountain, becomes mou-annn; Beautiful, becomes buu-ful; forgotten, becomes forga-annn, and even news-casters saying Trevon Mar-ann, etc. Is this regional, bi-coastal, ethnic, or pious self edification? I understand "Ebonics," but feel it lazy, and it isn't just ethnic people doing this. What is happening? Do I need to change? I am not racist....Ax me and I will tell you,...."No!"
