Articulation, often associated with speech production, is how people physically produce speech sounds. For people who speak fluently, articulation is automatic and allows 15 speech sounds to be produced per second. [30] An effective articulation of speech include the following elements – fluency, complexity, accuracy, and comprehensibility. [31]
Respiratory sounds can be produced by expelling air from the lungs. However, to vary the sound quality in a way useful for speaking, two speech organs normally move towards each other to contact each other to create an obstruction that shapes the air in a particular fashion.
A major distinction between speech sounds is whether they are voiced. Sounds are voiced when the vocal folds begin to vibrate in the process of phonation. Many sounds can be produced with or without phonation, though physical constraints may make phonation difficult or impossible for some articulations.
The sound of each individual's voice is thought to be entirely unique [13] not only because of the actual shape and size of an individual's vocal cords but also due to the size and shape of the rest of that person's body, especially the vocal tract, and the manner in which the speech sounds are habitually formed and articulated. (It is this ...
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.
The only language where such sounds are known to be contrastive in normal vocabulary is the extinct ritual language Damin (also the only language outside Africa with clicks); however, Damin appears to have been intentionally designed to differ from normal speech.
In linguistics, articulatory phonetics is the study of how the tongue, lips, jaw, vocal cords, and other speech organs are used to make sounds. Speech sounds are categorized by manner of articulation and place of articulation. Place of articulation refers to where in the neck or mouth the airstream is constricted.
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 ...
