a. Recall the context

b. Retain the text

c. Reproduce it in the test

We can remember the words, phrases and expressions easily based on the context. Human brain has two kinds of memory -- Short term memory (STM) and Long term memory (LTM).

Let the native speakers' idioms and slang be saved in your long term memory by consistent practice. One can speak like a foreigner when the accent is imitated by observation. Contextual language learning is the best technique.

Make the most of the smart phones in recording your accent, phrases and expressions. Always play back and self-remedy by comparing it with the original spoken tape. Watch the videos by native tutors. Watch English movies and songs. The rhythm, music, lyrics, words and tune can be immensely beneficial to acquire the native speakers' accent and style of interaction.

Native speakers use lots of idioms and phrases in their spoken communication. Idioms do not make sense when understood literally. Some of the examples are in the blink of an eye ("very fast") or it's a piece of cake ("easy") can add a level of sophistication to your English and make you sound more like a native speaker.

In order to sound more like a native English speaker, what you say is as important as how you say it. Improving the pace, clarity, and stress and unstress on the words of your speaking will go a long way in improving your fluency and help native speakers to better understand you.

6. Read aloud and sound like Native speaker

Reading aloud in English is a great way to work on the clarity of your pronunciation. If you've spent enough time listening to native speakers, try to mimic the way they talk. Allow your voice to rise and fall with the natural flow of the language.
