The human voice consists of sound made by a human being using the vocal folds or vocal cords for talking, singing, laughing, crying, screaming, etc. 

The human voice is a frequency which ranges from about 60 to 7000 Hz.
It is the vocal cords that produces sound when a person speaks.

Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; 1: the lungs, 2: the vocal folds(vocal cords) within the larynx, and 3: the articulators. 

Purpose of the lungs:


The purpose of the lung (the pump) is to produce adequate airflow and air pressure to vibrate vocal cords, (this air pressure is the fuel ofthe voice). 

Purpose of the vocal cords:


The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. 


The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine tune’ pitch and tone.
 
The tone of voice may be modulated to suggest or to express emotions such as anger, surprise, hate, love, or happiness, thus the voice also could be a reflection of ideas, external frequency of stimuli which influencies someone’s vocal code into the act of speaking.


which means that people can speak things that they pick up or download from their environmental energies, frequency of nocturnal spiritual presence, and radio frequencies…
