In human speech, egressive sounds are sounds in which the air stream is created by pushing air out through the mouth or nose. The three types of egressive sounds are pulmonic egressive (from the lungs), glottalic egressive (from the glottis), and lingual (velaric) egressive (from the tongue). The opposite of an egressive sound is an ingressive sound, in which the airstream flows inward through the mouth or nose.

Pulmonic egressive

Pulmonic egressive sounds are those in which the air stream is created by the lungs, ribs, and diaphragm. The majority of sounds in most languages, such as vowels, are both pulmonic and egressive. Pulmonic egressive sounds are found in all spoken languages. [1]

Glottalic egressive

Glottalic egressive sounds are known as ejectives.

Lingual egressive

The lingual egressive, also known as velaric egressive, involves a double closure similar to that of the lingual ingressive sounds known as clicks, but with airflow in the opposite direction. With the velum closed, the speaker forces air out of the mouth using either the tongue or cheeks, as in the French expression of dismissal. While not known to be used for normal vocabulary in any human language, [2] apart from the extinct Australian ritual language Damin, a variation of this airstream mechanism is known to musicians as part of circular breathing.

In articulatory phonetics, the manner of articulation is the configuration and interaction of the articulators when making a speech sound. One parameter of manner is stricture, that is, how closely the speech organs approach one another. Others include those involved in the r-like sounds, and the sibilancy of fricatives.

<span class="mw-page-title-main">Phonetics</span> Branch of linguistics that comprises the study of the sounds of human language

Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech, how various movements affect the properties of the resulting sound, or how humans convert sound waves to linguistic information. Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones, and it is also defined as the smallest unit that discerns meaning between sounds in any given language.

In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.

The field of articulatory phonetics is a subfield of phonetics that studies articulation and ways that humans produce speech. Articulatory phoneticians explain how humans produce speech sounds via the interaction of different physiological structures. Generally, articulatory phonetics is concerned with the transformation of aerodynamic energy into acoustic energy. Aerodynamic energy refers to the airflow through the vocal tract. Its potential form is air pressure; its kinetic form is the actual dynamic airflow. Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound.

The bilabial clicks are a family of click consonants that sound like a smack of the lips. They are found as phonemes only in the small Tuu language family, in the ǂ’Amkoe language of Botswana, and in the extinct Damin ritual jargon of Australia. However, bilabial clicks are found paralinguistically for a kiss in various languages, including integrated into a greeting in the Hadza language of Tanzania, and as allophones of labial–velar stops in some West African languages, as of /mw/ in some of the languages neighboring Shona, such as Ndau and Tonga.

<span class="mw-page-title-main">Palatal click</span> Consonantal sound

The palatal or palato-alveolar clicks are a family of click consonants found, as components of words, only in southern Africa. The tongue is nearly flat, and is pulled back rather than down as in the postalveolar clicks, making a sharper sound than those consonants. The tongue makes an extremely broad contact across the roof of the mouth, making correlation with the places of articulation of non-clicks difficult, but Ladefoged & Traill (1984:18) find that the primary place of articulation is the palate, and say that "there is no doubt that should be described as a palatal sound".

<span class="mw-page-title-main">Alveolar click</span> Click consonant sound

The alveolar or postalveolar clicks are a family of click consonants found only in Africa and in the Damin ritual jargon of Australia. The tongue is more or less concave, and is pulled down rather than back as in the palatal clicks, making a hollower sound than those consonants.

In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation and articulation, it is one of three main components of speech production. The airstream mechanism is mandatory for most sound production and constitutes the first part of this process, which is called initiation.

In phonetics, ingressive sounds are sounds by which the airstream flows inward through the mouth or nose. The three types of ingressive sounds are lingual ingressive or velaric ingressive, glottalic ingressive, and pulmonic ingressive.
