The Human Voice.
The sound produced in a person's larynx and uttered through the mouth, as speech or song.
The human voice consists of sound made by a human being using the vocal tract, including talking, singing, laughing, crying, screaming, shouting, humming or yelling.
The human voice frequency is specifically a part of human sound production in which the vocal folds (vocal cords) are the primary sound source.
(Other sound production mechanisms produced from the same general area of the body involve the production of unvoiced consonants, clicks, whistling and whispering.)
Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx (voice box), and the articulators.
The lungs, the "pump" must produce adequate airflow and air pressure to vibrate vocal folds.
The vocal folds (vocal cords) then vibrate to use airflow from the lungs to create 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 articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen or weaken it as a sound source.
The vocal folds, in combination with the articulators, are capable of producing highly intricate arrays of sound.
The tone of human voice may be modulated to suggest emotions such as anger, surprise, fear, happiness or sadness.
The human voice is used to express emotion, and can also reveal the age and sex of the speaker.
Singers use the human voice as an instrument for creating music.
Voice modulation in spoken language.
Human spoken language makes use of, the ability of almost all people, in a given society to dynamically modulate certain parameters, of the laryngeal voice source, in a consistent manner.
The most important communicative, or phonetic, parameters are the voice pitch, (determined by the vibratory frequency of the vocal folds), and the degree of separation of the vocal folds, referred to as vocal fold adduction (coming together) or abduction (separating).
The ability to vary the abduction or adduction of, the vocal folds quickly has a strong genetic component, since vocal fold adduction has a life-preserving function, in keeping food from passing into the lungs, in addition to the covering action of the epiglottis.
Consequently, the muscles that control this action are among the fastest in the body.
Children can learn to use this action consistently, during speech at an early age, as they learn to speak, the difference between utterances such as "apa", (having an abductory-adductory gesture for the p) as "aba", (having no abductory-adductory gesture).
They can learn to do this well, before the age of two, by listening only to the voices of adults around them, who have voices much different from their own, and even though the laryngeal movements causing these phonetic differentiations are deep in the throat, and not visible to them.
If an abductory movement or adductory movement is strong enough, the vibrations of the vocal folds will stop (or not start).
If the gesture is abductory, and is part of a speech sound, the sound will be called voiceless.
However, voiceless speech sounds are sometimes better identified as containing an abductory gesture, even if the gesture was not strong, enough to stop the vocal folds from vibrating.
This anomalous feature of human voiceless speech sounds is better understood, if it is realized, that it is the change in the spectral qualities of the voice, as abduction proceeds, that is the primary acoustic attribute, that the listener attends to when identifying a voiceless speech sound, and not simply the presence or absence of human voice, (periodic energy).
An adductory gesture is also identified, by the change in voice spectral energy, it produces.
Thus, a speech sound having an adductory gesture may be referred, to as a "glottal stop", even if the vocal fold vibrations, do not entirely stop.
Other aspects of the voice, such as variations in the regularity of vibration, are also used for communication, and are important for the trained voice user to master, but are more rarely used in the formal phonetic code of a spoken language.
Vocal Cord - The Source of Human Voice.
The means of communication is enormously essential, for the well-being of any animal.
Even micro-organisms communicate with each other, by means of chemicals.
Fortunately, our means of communication are far better than that.
We rely on it, every day to interact with others.
As is the case with walking, seeing, etc, we tend to take it, for granted.
The human voice is immensely versatile, and rich, both in range and content.
We use it to laugh, cry, scream, shout, sing and the list goes on.
The human voice produced, by the vocal cord is capable of producing highly intricate sounds.
You can tell, if your mother is angry at you, by her voice.
Some people do one better, and can tell, if people are lying just by their voice.
The Main Parts of Human Voice Production.
Following are the main parts of human voice production:
The power source: Lungs.
The vibrator: The voice box.
The resonator: Throat, nose, mouth, and sinuses.
The Power Source: Lungs.
The lungs here perform the essential function of, supplying adequate airflow, and air pressure in order to vibrate the vocal cord.
When we inhale, we draw air into the lungs.
This air is then exhaled, creating a stream of air, through your wide pipe and throat.
This exciting air provides the energy, to vibrate the vocal cords, in the voice box to produce sound.
If you want to make loud sounds, you have to exhale hard, to create a strong airflow.
The Vibrator: The voice box.
The part of the throat that moves, when you swallow is known as a voice box.
The Voice Box (Larynx) sits, on the top of the wide pipe.
The voice box is a part of the wide pipe, and the air exhaled from your lungs, passes through the voice box.
The vocal cord consists of two tight strings, that open during breathing, and close when you exhale to make a sound.
They vibrate very fast, almost from 100 to 1000 times per second.
You may vary the pitch, which explains the concept of frequency, pitch, etc. by controlling the tension, in the muscles in the voice box.
The vocal cord is also known as a vocal fold.
The vocal cord modulates, the flow of air from the lungs and into it.
The Resonator: Throat, nose, mouth, and sinuses.
Vocal cord by themselves, produces only a buzzing like sound, much like a bee.
Sound is not created, by vocal cords.
Instead, it is created by the interactions of the vibrations created, by your vocal cord, with the muscles and tissues in your mouth, nose, throat and tongue.
When you talk, your tongue darts all around your mouth helping you pronounce complex syllables.
The vibrations are deliberately altered, in our throat, and mouth to produce, the unique human voice.
In below Image, it shows these body parts.
The components of the human voice generation system: vocal cord, throat, nose, etc..
You must have also noticed, a difference between the voice of a man and a woman.
This is thanks to the differently sized vocal cord.
This change in vocal cord size occurs largely, during puberty when the male’s voice becomes deeper, and the female voice becomes sharper and melodic.
Important Facts.
Vocal cords.
The vocal cords (voice reeds) are thick folds of throat tissues, which are responsible for generating sounds, through vocalisation.
Main layers of vocal cords.
Deep lamina Peoria, superficial lamina Peoria, squamous epithelium, thyroarytenoid muscle, and intermediate lamina Peoria are the main layers of vocal cords.
Human body parts which are collectively responsible, for the production of human voice.
Lungs are the power source, and the voice box is the vibrator.
Nose, throat, sinuses, and mouth act as the resonators.
Voice Box.
The voice box (larynx) is the region of, the throat comprising the vocal cords.
It is predominantly used, for talking and breathing.
The Human Voice in the Universe or the Space or the outside planet Earth.
No, a human voice does not move in the universe or the Space or the outside planet Earth.
The Sound does not travel in the universe or the Space or the outside planet Earth.
The Sound waves travel, through vibrations in a medium, like air or water or solid, and cannot travel through empty space.
In the universe or the Space or the outside planet Earth, there are no atoms or molecules to carry sound waves, so there is no sound.
The Sound waves lose, energy over time.
As they travel through a medium, causing them to get quieter, and quieter until they disappear.
The Sound waves are reflected, by mediums.
Like walls, pillars, and rocks, which is known as an echo.
Can you hear sound in space.
No, you cannot hear any sounds, in near-empty regions of the space.
The Sound travels, through the vibration of atoms, and molecules in a medium, (such as air or water or solid).
In the universe or the Space or the outside planet Earth, where there is no air, sound has no way to travel.
Is it possible, to send messages, through brain waves of the human?.
Technical telepathy is the best method.
The electrical nature of the brain allows, not only for sending of signals, but also for the receiving of electrical pulses.
These can be delivered, in a non-invasive way, using a technique called transcranial magnetic stimulation (TMS).
What is the highest brain wave in Humans?.
Gamma brain waves are the fastest brain waves, produced inside human brain.
Although, they can be hard to measure accurately, they tend to measure above 35 Hz, and can oscillate as fast as 100 Hz.
Human brain tends to produce gamma waves.
How to measure brain activity in humans.
The Human Brain, is difficult to study, not only, because of its inherent complexity;
The billions of neurons, the hundreds or thousands of types of neurons, the trillions of connections.
The Human Brain, also works at a number of different scales, both in the physical sense and in the time domain.
To understand, the human brain’s electrical activity at these scales, no single technology is enough.
As a result, neuroscientists have a suite of tools, at their disposal.
Some of these, such as fMRI and EEG, can be used in humans, because they are non-invasive; they work through, by looking into the skull, But, these tools suffer, from a lack of detail.
To get a more microscopic picture, of neuron activity, researchers turn to human models.
This allows the behaviour of individual neurons, or small groups of neurons, to be analysed in much greater detail.
The main Questions, for which this mission exists.
1. The Human Mouth, and The Human Ears are having, fixed distances, and standard range.
2. The Sound speed is, only 343 meter per second.
3. The Diameter of the Planet Earth, is 12756 killometer, that is 1 crore, 27 lakh, 56 thousand, Meter.
