Improving one's accent is a long journey. At first, you should ask yourself what accent you want to have. American, British, Australian accent? American or British from which region or city? New York, Dallas, London or some other British accent? Be aware that some cities (London, for example) have more than one accent. If you already know the accent you have to start listening to radio programs, podcasts and regional TV channels. Talk as much as you can to people that have the accent you want to acquire. If possible go to the place where that accent you want to learn is spoken. If you really want to change your accent, wait, wait and wait because the change is not too fast, unless you are a child. Children can change their accent more quickly. Personally, I don't much care about accents. Communicating clearly is my goal when I learn a new language.

If you speak too quickly, and with the wrong intonation and rhythm, native speakers will have a hard time understanding you. Don't worry about your listener getting impatient with your slow speech -- it is more important that everything you say be understood. * Listen to the 'music' of English. Do not use the 'music' of your native language when you speak English. Each language has its own way of 'singing'. * Use the dictionary. Try and familiarize yourself with the phonetic symbols of your dictionary. Look up the correct pronunciation of words that are hard for you to say.
