One of the best ways to improve your listening skills is to engage in conversations. Of course, italki is a great place to do just that, whether you find a Language Partner, a Community Tutor, or a Professional Teacher. Find someone to talk to and that will help you learn to listen, as well as to speak. Other ways to improve your listening skills are by watching movies, TV shows, or by listening to the radio. You can do all of these online. It's important to study and practice your target language frequently and consistently, which will help you to better understand when you are listening to programs in English. Repetition is important, also. You shouldn't just listen to a program once a week and expect to get good results. Find a movie in English that has subtitles in your native language. Focus on listening to the English dialogue and just use the subtitles to make sure you're correct. The more you do this, the less you should rely on the subtitles. Again, the best benefit from this method depends on you studying your language frequently. For television programs, one of the best things to watch for language students is the news. News broadcasts are usually evenly paced and use standard, correct language that isn't too difficult to follow. Newspapers tend to be written on an approximately 8th grade comprehension level and television newscasts do pretty much the same thing. Watching the people speak helps, also, because it's easier to understand someone when you can see them. Listening to the radio can be a good method, also, but try to listen to spoken word programs, such as the news, or sports programs. Some people feel that listening to music is a good way to learn a language, but personally, I don't feel that it's a preferable method for beginners. Songs are often not sung in a natural voice and tend to be stylized and may rely too heavily on slang.
