How to enhance once voice quality

Hello!

I am planning to produce my own videos and share it online especially on YouTube and on my blog dealing with web hosting reviews , but the problem with me is that I am not satisfied with my voice and tone quality in my videos. There is one more problem, I am not a native western so my pronunciation is not of native type. I Know it's fine for my country audience but how about people from other countries. They will find it it hard to understand.

I wanna look like a pro in my videos. Can anybody have any idea about any technology which could help me, tuning my voice quality and converting my pronunciation into american type.

Please any suggestion is Appreciated!

Share how you guys out there manage to produce master piece videos.

Thanks!
