Communication Guru said that in communication process it consists of 7% spoken words, 38% of tone of voice and 55% of non-verbal (body language).
Yes, that's right. I have been taking advantage of the 55% of body language. Most clients I gave my interpreting services came from the refugee background and unfortunately these people couldn't have a chance to have a formal education. Some people of those were born in refugee camp and their communication skills are at lowest level, so that sometime even communicating with the same language they lack understanding to complex nature of the dialogues. When I used body language in addition to verbal interpretation it helps them a lot to understand and on the other hand the body language assured the English speaker that the message is well delivered.
I recollected a story that I had been told by one of the doctors from Royal Adelaide Hospital, Chest Clinic, while I had been assisting in the process. He said, one remote area in China a farmer was having a meal in his kitchen. A couple of ducks came into the kitchen through a door, which was open. The farmer said, "Get out" pointing his finger to the opening door. At once ducks went out. The doctor told me with a smile on his face that ' wow, animal understands'. I said, yes, it does, it is non-verbal communication. Even if animal understands non-verbal communication human can understand more easily whether they came from refugee background or they have low level of education. Interpreting is not a big problem if proper body language is used.
Communication has done sometime even if no word is spoken. For example, 'silence denotes admission'.
