When the vocal folds come together and vibrate as air flows through them during the exhale of air from the lungs, they make sound. The sound wave for your voice is produced by this vibration. The vocal folds must vibrate together symmetrically and frequently in order for the voice to be clean and not raspy or scratchy. As you age, your vocal chords may tighten up, which can cause a voice change.
There are two types of voices: soprano and contralto. These terms describe the relative size of the two vocal cords that produce each note. For example, a soprano voice has larger cords than a contralto voice. Both men and women have these two sets of vocal cords, but most people only use one set at a time when speaking.
The way in which you use your voice determines its quality. Your voice can be cultivated or untrained. An untrained voice is one that is without training or education. This means that you use it without thinking about what you are saying or how you are saying it. The quality of an untrained voice is poor; it can be loud or soft, clear or muddled sound. A trained voice on the other hand has been cultivated through practice and education. It can be used for music or speech. A trained voice is better because it can be controlled in terms of volume and tone. Also, a trained voice is more likely to be understood by others.
The pitch of the voice is determined by the pace of vibration. For example, the voice becomes higher when the vibration rate is faster.
The voice box (larynx) is a muscular organ located in the neck just below the throat. It functions to produce voices. The larynx is made up of two main parts: the cartilaginous framework and the soft tissue lining the framework. The framework consists of seven bones called cartilages that support the soft tissue. The soft tissue includes two membranes called vocal cords that move up and down inside the frame like a pair of lips across which air can flow when you speak.
The muscles that control the movement of the vocal cords are called the pharyngeal constrictors. There are three of these muscles: the thyrohyoid muscle, the sternothyroid muscle, and the omohyoid muscle. They are attached at one end to the body or skull and at the other end to the thyroid gland or its ligaments. These constrictors pull the vocal cords closed against the trachea (windpipe) to make sounds.
How do our voices produce sound? The vocal folds are located towards the top of the airway. The vocal folds pull together and vibrate during exhale, stopping air passage. The number of times the folds vibrate every second, however, is determined by the pitch being sung. For example, the higher the note, the more times per second the folds vibrate.
The sound that comes out of our mouths travels in waves through the air. These waves impact other parts of your body along the path they take until they are stopped by something solid. The ears receive the sound wave first, which then transmits it to the brain via the auditory nerve. Voice sounds follow a similar pathway from mouth to brain.
However, since voice sounds travel in waves through the air, they will affect other objects along their route. For example, if you shout "Hey!" into the empty hallway, your voice will travel down the hall and be heard by anyone who might be walking down it. As it passes through the walls, doors, and people, its energy will trigger any motion detectors or lights that are nearby. As this happens, notice what happens to your voice. It gets louder as it goes away from you and softer as it approaches another person. This is how we can communicate over long distances using only our voices.
Since voice sounds travel through the air, they will be affected by weather conditions.
The voice is the sound generated in the larynx by the vibrating of the vocal folds (vocal cords). This vibration produces certain speaking sounds. The vocal folds are considered to be abducted when they are separated, and adducted when they are closed. Vocal folds abducted (open) for longer periods of time will produce a rough voice; adducted (closed) for longer periods of time will produce a smooth voice.
The muscles of the larynx are responsible for controlling its size and shape. These muscles include the thyrohyoid muscle, which attaches to the thyroid cartilage and helps rotate it left and right; the sternothyroid muscle, which attaches to the middle part of the sterno-thyroid articulation and helps rotate it up and down; and the cricothyroid muscle, which attaches to the upper end of the cricoid cartilage and helps tilt it back and forth. The posterior portion of the larynx is attached to the spine by the soft tissue and bones called the pharyngeal wall. The pharyngeal wall consists of three portions: the oropharynx, the nasopharynx, and the hypopharynx.
The oropharynx is that part of the mouth cavity behind the teeth but in front of the tongue and palate. It includes the oral cavity, the nasal cavity, and the sinuses.
The vocal folds, in conjunction with the articulators, are capable of creating extraordinarily complex sound arrays. A person's tone of voice can be adjusted to convey emotions such as anger, surprise, fear, happiness, or sadness. Also, the way a person speaks can be interpreted by others who know him or her well.
The average human voice has five distinct pitches that can be produced by varying the width of the glottis (the opening between the vocal cords). These pitches correspond to the notes G, D, E, F, and C above middle C. Other pitches can be added to these basic tones if necessary; for example, a speaker may slightly widen the gap between the vocal cords to produce a higher pitch.
When people talk about the "voice of God", they are usually referring to the highest pitched tone that can be achieved without using your lungs as a resonator, which is called the "tenor" note. This note is generally considered to be around G4 when spoken by someone of moderate size. However, there are male speakers who can reach G5 or even higher if they use their throat rather than their chest as a resonator.
