Lessons with tutors can help you with pronunciation and vocabulary. The tutor can model accurate pronunciation and suggest vocabulary in topics you are interested in.

A helpful tool for pronunciation is to share an article with a language partner.  You can read a short portion and then your partner can correct you.  If your primary interest is pronunciation and improving vocabulary, this approach is efficient.  Having a discussion helps you to think and understand quickly but often does not give the opportunity to receive corrections.
