how can I do more practice as I m confused in conversation with others, I am not confident that I am pronouncing correctly or not?

Ohho If you want to speak English so first of all you have to leave your "saram". and build confidence inside you. Never thought what other think about you and your pronunciation. English is not a big deal. If you try to speak English a week regularly then you will be good speaker. And try to think also in English. use good grammars and keep learning on this app. I think this may help you. Good morning. Have a good day to u dear friend.
