Speak more with friends or with teachers here like me! Watch more movies and take good note of their pronunciation. Prepare and practice speech or dialog speeches! Google any word that you're not sure how to pronounce it and listen to its pronunciation.

The way i use to improve my speaking skills is speaking with myself during the day. While doing courses and staff around the house i keep talking to myself and discussing topics that I'm interested in. I know it seems crazy but it works.

I know how it sounds, but to improve speaking skills you need to speak more! You can find an exchange language partner (someone who is interested in learning your language and talk to them first in English, then in your language) or a community teacher and talk to them for money. I think you could also check out Facebook groups of students who are learning English and talk to the members.
