Asalamulikum

Dear if u want to be a good orator then u should start speaking.coz regular speaking will help u and by this way u can hold strong command on spoken language.dear i will try to give u some suggestion to reach out u in this regard,coz i had the same problem.

1)Dear if u wana improve ur spoken skills then u have to take input that is listening,coz listening is an input for spoken.likewise, reading is an input for writing.
2)Speak no matter how much hard is that for u.
3)Speak wid someone in order to have discussion and learn more ideas wid others.
4)If there is no one speak wid ur own self i used to and now i feel that i have brought considerable change in my own spoken language .
5)when ever u are alone in ur room take any topic and then start speaking on that topic and keep on doing the same drill.
Inshallah u will hit the bull eye soon,but if u are committed and having workaholic spirit.

waslam
regards
