The term communication is really a multifaceted one, but in its essence is defined as an exchange of messages through a vehicle, the voice, and a code, the language, which is shared among a common group of humans beings.
If we were to pause for a moment to think about everything we do unconsciously when we utter a single sentence, we would be truly amazed. If we only had to think consciously and to control with precision breathing, posture, balance and body language, articulation and coordination for speech signals, facial expressions and all the rest, our brain would not have time to think logically about anything else.
In human reality, our capabilities consciously are very limited. According to the latest medical studies, less than 10% of the population is able to do two things at the same time. Many people are convinced that they are able to do more than two, but they are only deluding themselves that they are in control.
Having clarified this concept, it’s obvious to everyone that, when communication fails, the cause for the famous line “I didn’t get it”, or “I’ll let you know”, that we have all been told many times in life, needs to be understood, not as to what was done or said consciously, but what was communicated or missing unconsciously.
This step is critical as all of this teaches us how to “add” something to our own way of communicating, without worrying about our “voice” tool and without analyzing all the instinctive behaviors that each of us has developed through our own personal life experiences.
To give an example that is even more simple to understand; if each of us began to recite a poem from memory in front of an audience, such as "The Infinite" by Leopardi, you would get the same results whatever Public Speaking or personal Growth course you had followed, as all teaching would be aimed at adding something to the content and use of the voice, body, face and emotion.
