English is a foreign language and joint efforts is needed to learn so as to overcome limitations.

I m teaching English from last 8 years. Grammar Diction , Intonation,  Syllable,  are my core area.

Considering sentence construction is very Important for individuals.

Vocabularies has a energy that gets you there on stage and speak for hours and hours.

Pronunciation gives you command over language. 

Building Scenarios will help you gain trust from the audience.

Finally you must learn and earn using English day in and day out. People must see your recommendations and Inputs in their challenges with this language.

Voice Authority comes with huge set of skills not limited to confidence , vocal functions and Articulation.

I admire people who are willing to fight and debate in English.

Because when you are high on emotion such as Anger your mind gets out of control.

So learn to debate more in English.
