The most convenient context for conversational practice may be in structured language learning sessions, where someone is consciously helping you to learn the language. If you have one or more persons who are employed to help you on a daily basis, those people will be accustomed to speaking with you. They will have a good feel for your current level of ability, and thus will be in a good position to make sure that what they say to you is comprehensible. There is a low stress level involved in conversing with a familiar person in a familiar setting, when compared with conversing with all the people you happen to encounter out in the world at large.
In addition to formal language sessions, you will increasingly be able to engage in conversation with friends. For them, conversing with you is hard work at this point, so it requires some commitment on the part of your conversational partners. But again, people who know you well will be able to communicate with you far more effectively and easily than people who do not yet know you. Even though you can find out many ways to learn one new language, you should select one to help you learn it effectively. Cheap Rosetta Stone is supposed to be one of the best ways in language learning.
