8) Practice for at least 30 minutes every day
There is no way around it: the only way your pronunciation will improve is if you practice, practice, practice! Your pronunciation will not magically improve just because you’re speaking English. The sounds of English may be very different from the sounds in your language. It may be difficult and even uncomfortable for your mouth to make some of the sounds in English.
You need to practice with a purpose. Practice the sounds of English until they feel as natural and comfortable as the sounds of your language. It won’t happen overnight, but gradually your pronunciation will improve.
