Not Like a Guitar String Vocal folds vibrate when excited by aerodynamic phenomena; they are not plucked like a guitar string. The Process of Voice. Footer Search this website. Join Our Mailing List.

The vocal folds are two small muscles that have a moist covering, within the larynx. When you breathe, the vocal folds are open to allow air to flow from your upper airway into your trachea and lungs. When you want to speak, you close your vocal folds and begin to exhale, causing an increase in pressure that starts them vibrating cyclic opening and closing. The buzzing tone created by the vocal folds becomes what we know as the human voice through resonance system 3.

Resonance is the shaping and amplification of the sound waves of the vocal tone. The length and shape of the vocal tract influences the shaping of this tone, as well as what structures or cavities the sound waves may bounce off of.

Voice is not always produced as speech, however. Infants babble and coo; animals bark, moo, whinny, growl, and meow; and adult humans laugh, sing, and cry.

Voice is generated by airflow from the lungs as the vocal folds are brought close together. When air is pushed past the vocal folds with sufficient pressure, the vocal folds vibrate. If the vocal folds in the larynx did not vibrate normally, speech could only be produced as a whisper. Your voice is as unique as your fingerprint. It helps define your personality, mood, and health. Approximately Disorders of the voice involve problems with pitch, loudness, and quality. Pitch is the highness or lowness of a sound based on the frequency of the sound waves.

Loudness is the perceived volume or amplitude of the sound, while quality refers to the character or distinctive attributes of a sound. Many people who have normal speaking skills have great difficulty communicating when their vocal apparatus fails. This can occur if the nerves controlling the larynx are impaired because of an accident, a surgical procedure, a viral infection, or cancer.

Humans express thoughts, feelings, and ideas orally to one another through a series of complex movements that alter and mold the basic tone created by voice into specific, decodable sounds.

Speech is produced by precisely coordinated muscle actions in the head, neck, chest, and abdomen. Speech development is a gradual process that requires years of practice.
