Pronunciation
Last but not least, examiners will score your pronunciation. Those with the highest scores in this category will pronounce words well enough for native speakers to understand them perfectly at all times. Pronunciation problems which limit your ability to be understood when speaking will reduce your score.
It's important to remember that English pronunciation involves more than just the sounds of words. Native speakers will also be listening for proper tone, stress, and flow in your words as well as within sentences. When test-takers are unfamiliar with the natural rhythm and intonation patterns of English, the only surefire way to improve is to hear and use as much spoken English as possible throughout the day. You can speak English and listen to your response every day right here at BestMyTest with our IELTS speaking practice questions.
Realistically, doing this may not be possible for everyone. Even so, you can still make the most of your limited time by listening to recordings of native speakers. To practice improving your pronunciation, you'll need to channel your inner parrot. Try stopping the recording and repeating short portions exactly the way you heard them a few times. Listen for rising and falling tones, pauses, and even the speaker's emotion. Doing this will allow you to develop your own pronunciation within different contexts, as well as train yourself to hear and replicate the real sounds of native-like English.
Free IELTS Speaking Test Resources
Improving your speaking skills with free resources is a little more challenging than the other three IELTS sections. It's true that speaking English can help you improve, but what really helps is having conversations with a fluent English speaker. Someone that can help correct your mistakes. Of course, a fluent English speaker isn't always available, so we'll go to the next best thing. Free IELTS speaking resources.
