Vocal folds (speaking) In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent ...
The vocal timbres created by physical changes in the vocal fold vibrations and muscular changes in the laryngeal muscles are known as glottal configurations. [11] These configurations happen as a result of adduction and abduction of the glottis. A glottal configuration is the area in which the vocal folds come together when phonating.
The histological structure of the vocal fold can be separated into 5 [2] or 6 [3] tissues, depending on the source, which can then be grouped into three sections as the cover, the transition, and the body. The cover is composed of the epithelium (mucosa), basal lamina (or basement membrane zone), and the superficial layer of the lamina propria.
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 ...
Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general. Phoneticians in other subfields, such as linguistic phonetics, call this process voicing, and use ...
The vibration produced is an essential component of voiced consonants as well as vowels. If the vocal folds are drawn apart, air flows between them causing no vibration, as in the production of voiceless consonants. [7] The glottis is also important in the Valsalva maneuver. Voiced consonants include /v/, /z/, /ʒ/, /d͡ʒ/, /ð/, /b/, /d/, /ɡ ...
The frequency of vibration of the vocal folds is determined by their length, tension, and mass. As pitch rises, the vocal folds are lengthened, tension increases, and their thickness decreases. In other words, all three of these factors are in a state of flux in the transition from the lowest to the highest tones. [17]
Falsetto (/ fɔːlˈsɛtoʊ, fɒl -/ fawl-SET-oh, fol-, Italian: [falˈsetto]; Italian diminutive of falso, "false") is the vocal register occupying the frequency range just above the modal voice register and overlapping with it by approximately one octave. It is produced by the vibration of the ligamentous edges of the vocal cords, in whole or ...
