Improving intonation, accent reduction

I need to improve the "impact" of my delivery. This was one of the development needs that my manager has in mind for me.

Thats true, even if you have stuff, and you are not able to convey it in a manner people are impressed, most of the hardwork goes waste..

My voice is monotonous - no up's and down's in the frequency.. It is a drone.. When you listen to me, you would feel that you are listening to a truck that speaks :)..

I also need to improve my accent [So that my US counterparts get me properly]

I need speech processing software to analyse, improve and monitor my voice.
