The expression of the face communicates emotions
Recognizing who is lying is easy if you learn to observe the face. That's exactly why here at Inborn Voice we teach you to first learn how to watch so you can then find out when you are lying, even to yourself.
The face speaks
Facial expression translates someone's deepest thought or feeling into something easily readable by any observer. On the other hand, if we think about our physiological growth, we have all developed first hearing , then listening, then touch, then listening , followed by sight and sensing. They are all senses able to make us interact and recognize in the world what we like and what we don't. It is no wonder that a child in diapers smiles at a smiling face and starts crying in front of an angry face.
In essence, we learn to react first to what we see and feel that to what we " listen ". In fact, language is a layer of communication that has evolved subsequently to hearing and that requires the support of the grey matter of the brain, while "feeling" is part of the reptilian part of our brain: an instinct, a sixth sense.
The eyes as a sixth sense
When we receive a verbal message we always interpret it accompanied by the different non-verbal languages that we elaborate unconsciously, that is what we report as "sixth sense". In reality it is not an abstract or paranormal perception, we have simply decoded the signals of the face on the basis of our previous experience.
This step is fundamental to achieve effective communication, and as you may have guessed it requires a path of personal growth and not just voice improvement.
When the message expressed through language, by voice, brings a different meaning from the one transmitted by the expression of the face, our brain tries to identify the best meaning. If the face says "I'm not interested" and the voice says "I'm interested", our brain will give priority to visual messages and not to auditive ones, i.e. it will perceive a "lie". In reality, maybe the person was just worried about making a bad impression and wasn't lying, but unconsciously we classified him or her as not "reliable".
Only a good Vocal Coach can teach you how to handle all these aspects of communication, which as you may have understood is not limited to the voice alone, but is a much larger and more complex world than you initially believed.
