While there are multiple ways one can improve one's skill in spoken English, the first and foremost thing to do, ideally, is to find out the areas challenging one's ability to speak fluently, correctly and confidently in English. Once that is done, then the next steps become more guided, whether by self or a mentor, and the rest becomes quite easier through regular and dedicated hours of practice.
