Most of the time, the difficulties in English speaking lie in listening, pronunciation, vocabulary and confidence. If you can overcome these challenges, there will be a huge improvement in your speaking skill.
1. Listening
When it comes to conversation, 50% of the time is spent talking and the other 50% spent listening to the other person speak. It is difficult to reply if you don’t understand what they are saying.
You can also use these phrases in conversation when you don’t understand something: “I’m sorry, I didn’t understand that.”; “Could you repeat that, please?”, “Could you say that again, please?”
2. Pronunciation
It can be difficult to pronounce English words. When speaking English, you have to consider not just word pronunciation but the connections between the words in the sentence. Rhythm and intonation of the sentence are other difficult things.
3. Vocabulary
Sometimes it is difficult to say what you are thinking because you are missing two or three important vocabulary words.
4. Confidence
If you feel nervous and are afraid of making a mistake when speaking English, then confidence is your problem. Not worrying too much about grammar.
This is one of the best way to learn English quickly _ talk to yourself; talk with your teachers and friends in English class. If you make a mistake, they can correct you. It is important to practise in less-pressurised situations as much as possible to increase your confidence. Then you will be more comfortable speaking English in high-pressure situations.
