How much has my speeking skill improved for a week?

What should

I do to improve my pronunciation? Slur is difficult, and to make my speech intone is also difficult😭

【This is the one part of Selena Gomez's speech】

I’d be lying if I said that I've never tried to make myself better by giving in because I have, but I’ve learnt from my actions, and for all of the things I’ve done I’m proudest of that I’ve learnt from my mistakes. I want you to know what it’s like that I know what it’s like. Figuring out what types of friends you have, you are who you surround yourself with.

So I just want to say I hope I can inspire each and every one of you to just trust in yourselves, to love and be loved.
