Voice
Your attitude is projected through your voice as well as your body language. Make sure your body language and voice always says, “I’m here to help as best I can.”
When your voice is annoyed, impatient, or condescending, the other person may become angered or angrier. Speak with a calm, firm, caring, soothing tone. Your communications will be more relaxed, more pleasant, and better understood.
The speed and rhythm of your speech is important as well. Clear communication includes appropriate pauses and inflections to support the words.
