Listen and talk more. Listen to television and movies in English that sound natural to you and try to copy the way they say the words. Notice the muscles around their mouths and as you try to sound like them, visualize your own facial muscles and breathing. Your voice in the new language will likely sound different from your voice in your own language- not just the individual sounds. If your new language has sounds that are not used in your native language, you may not be able to hear them any more. If this is the case, just do your best to sound like what you do hear. They should be able to understand you even if they can tell you are not a native speaker. As a native English-speaker, I want to say, "Thank you for learning English and don't worry too much about an accent as long as you can be understood."

You will always have your own accent, it is not important so long as people can understand you. The best way to sound more natural is to learn natural phrasing or collocations, two or three words that go natural together.

Yes indeed I agree with collocations and watching movies... I would actually go even further than collocations (business trip, not ...journey) and focus on lexical chunks/phrases too (if I were you, I'd..., While you are X, could you Y, etc) Big question, How? Big answer, Reading! A page will have HUNDREDs of natural lexical phrases and if you read 20 pages an hour you are repeating them continually in your brain. Reading at about 8-12 years old is when a person's language really develops! As a student don't read books where you can't easily read many pages an hour. Choose a graded reader that means the reading is fun. Then of course regular speaking practice on Italki will get your brain to practice pulling those natural lexical phrases out of your subconscious memory!

Hi, Daisy! To follow up on John's comments, have you tried learning how to use phrasal verbs? These are verbs that contain more than one word and have their own meanings. An example in Spanish is "darse cuenta de," which together does not mean what the three words individually mean.

So, tell me your secrets; how have you handled it to make your accent sound natural?
