Hi! Good to know that you are thinking about people for better communication. I have some suggestions for you. Everybody has his own accent. People occasionally need time to process what is being said and formulate a response.
It is okay to ask someone to repeat anything or to be requested to do so yourself. Keep in mind that a poor understanding of English does not necessarily translate into a lack of intelligence. It takes understanding and patience to communicate across language and cultural difficulties
Learn about some strategies that are helping to grow communication among different cultures:
Know Yourself: Understand your motivation for researching this subject, including biases, assumptions, attitudes, and preferences.
Culture and Value: Learn about many cultures and values, both within and outside the United States.
Language: Use common language; avoid slang and jargon. Use everyday vocabulary.
Take your time: Avoid jumping to conclusions. Allow someone to finish, relax, and be flexible.
Consider the physical and human setting: Physical and human setting encompasses one’s physical environment and background, customs, previous practice, and timing.
Improve your communication abilities: Listen and pay attention. Concentrate on explicit signals while remaining sensitive to implicit clues. Be mindful of nonverbal clues and communication. Establish common aims.
Encourage feedback: Allow for message corrections and adjustments. Create a comfortable setting. Ask questions and pay close attention to responses.
Hope so! This information is enough for you to know about better communication.
