The average total lung capacity of an adult human male is about 6 litres of air. [1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [2] decreasing to 12–20 breaths per minute ...
[2] [3] [4] The tone of voice may be modulated to suggest emotions such as anger, surprise, fear, happiness or sadness. The human voice is used to express emotion, [5] and can also reveal the age and sex of the speaker. [6] [7] [8] Singers use the human voice as an instrument for creating music. [9]
The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...
Ingressive speech sounds are produced while the speaker breathes in, in contrast to most speech sounds, which are produced as the speaker breathes out. The air that is used to voice the speech is drawn in rather than pushed out. Ingressive speech can be glottalic, velaric, or pulmonic.
Voice projection is the strength of speaking or singing whereby the human voice is used powerfully and clearly. It is a technique employed to command respect and attention, such as when a teacher talks to a class, or simply to be heard clearly, as used by an actor in a theatre or during drill. Breath technique is essential for proper voice ...
Human vocal apparatus used to produce speech. The physical structure of the human nose, throat, and vocal cords allows for the productions of many unique sounds, these areas can be further broken down into places of articulation. Different sounds are produced in different areas, and with different muscles and breathing techniques. [28]
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 laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.
A voice type is a particular kind of human singing voice perceived as having certain identifying qualities or characteristics; vocal range being only one of those characteristics. Other factors are vocal weight , vocal tessitura , vocal timbre , vocal transition points , physical characteristics, speech level, scientific testing, and vocal ...
