The business environment of the 21st century is expanding to include people from cultures and countries around the world. It takes special skills to communicate across these many cultures. Your courtesy and respect help establish a good foundation for effective communication. People respond to courtesy and feel comfortable when they know they have your respect. This helps them to be open and willing to ask questions when they don't understand something. By making people feel comfortable, you help them to be better listeners. Avoid words that require a dictionary when communicating cross-culturally. Pepper your communication with words that everyone understands.

Step 1
Slow down when you speak. Allow those who don't have the same native language as you the time to interpret what you are saying.
Step 2
Speak clearly and concisely. Make eye contact and enunciate plainly. Avoid using ambiguous or dual-meaning words. One of the problems non-native-English-speaking cultures have with the English language is misunderstanding the many meanings one word can have.
Step 3
Keep it simple. Think in terms of your audience, and speak to their understanding. Don't make long speeches that lose your group. Allow listeners the time to soak in what you have said. Pay attention to your audience and be an active speaker and listener. You can ascertain a group's grasp of your communication by their response to your words.
Step 4
Maintain respect and courtesy for people who come from different cultures. When you respect the people you communicate with, this helps reduce the stress they feel when trying to understand what you are saying. Doing basic research on specific ways to interact with the cultures you will be coming into contact with is a great way to show your multi-cultural group that you respect them.
Step 5
Smile and be open. Your body language communicates your acceptance -- or non-acceptance -- and respect, as it helps put listeners at ease. Your body language conveys unspoken communication. Avoid large gestures with your hands, as this can be intimidating to people who might misunderstand your meaning. Keeping your arms crossed often makes people think you are not open to what they have to say.
Step 6
Avoid slang. Slang words are unique to individual cultures and not always interpreted correctly. To ensure effective cross-cultural communication, don't use slang words others might not know.
Step 7
Shun humor. What is funny in one culture might not be in another. Humor might be misunderstood and interpreted in a bad light. While humor is a good icebreaker, it can backfire when the cross-cultural group misses humor's meaning. When in doubt, avoid using humor when communicating with people from many cultures.
Step 8
Adopt a formal communication approach until you develop a rapport with your group. A casual, informal approach can be upsetting to people from different cultures, especially when you have just met them. Use a respectful and formal mode of speech until you have developed a relationship with your cross-cultural group.
Step 9
Stay away from using negative questions or answers. Double negatives are confusing enough to those with English as their native language. In a cross-cultural situation, double negatives are easily misunderstood. Keep questions and answers simple so everyone understands.
Step 10
Ask for feedback. Request members of the cross-cultural group to speak up and provide interaction or ask questions. When you permit two-way communication, this helps prevent misunderstandings and clears up questions people might have.
Step 11
Summarize what you have said. Don't assume that just because you said it everyone understands. Repeat what you have said in a different way, summarize it and allow people the time to grasp what you have said. By summarizing what you have said, you can verify that everyone is on the same page.
