Five Ways To Improve Your Spoken English At Home
First, you should improve your English pronunciation because good pronunciation will help people understand your spoken English clearly, even if you don’t know many words. Second, most English learners read too much and listen too little. If you want to improve your English speaking, spend more time listening! Listen to the audio while you read the text, then read the text out loud, trying to imitate the pronunciation you hear in the audio.
Then, reading English texts out loud will train your mouth and lips to pronounce English words more naturally. I suggest reading every text out loud twice. The first time, read slowly and focus on pronouncing each word correctly. Circle the words that are difficult to pronounce and repeat each one ten times. The second time, read faster and focus on making your English flow, speaking each sentence with a natural rhythm.
In addition, whenever you learn a new word, try saying it in a complete sentence. If you do this with every new English word you learn, it will help you speak English in complete sentences more naturally.
Finally, if you don’t have contact with native English speakers, watch TV shows and films in English with English subtitles to learn English conversation patterns.
