The alveolar ejective fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is sʼ, and the equivalent X-SAMPA symbol is s_>.

Features

Features of the alveolar ejective fricative:

Its manner of articulation is sibilant fricative, which means it is produced by directing air flow through a groove in the tongue at the place of articulation and directing it over the sharp edge of the teeth, causing high-frequency turbulence.
Its place of articulation is alveolar, which means it is articulated with either the tip or the blade of the tongue against the alveolar ridge, termed respectively apical and laminal.
Its phonation type is voiceless, which means it is produced without vibrations of the vocal cords.
It is an oral consonant, which means air is allowed to escape through the mouth.
It is a central consonant, which means it is produced by allowing the airstream to flow over the center of the tongue, rather than the sides.
The airstream mechanism is glottalic egressive, which means it is produced by pushing air with the glottis, rather than with the diaphragm.

The term

The term sibilant is often taken to be synonymous with the term strident

Fricatives (or spirants) are consonants produced by forcing air through a narrow channel made by placing two articulators close together. These are the lower lip against the upper teeth in the case of [f]

turbulence or turbulent flow is a flow regime characterized by chaotic, stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and time.

place of articulation (also point of articulation) of a consonant is the point of contact, where an obstruction occurs in the vocal tract between an active (moving) articulator (typically some part of the tongue) and a passive (stationary) articulator (typically some part of

Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the superior teeth.

An alveolar ridge (also known as the alveolar margin) is one of the two jaw ridges either on the roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth. The alveolar ridges contain the sockets (alveoli) of the teeth.

An apical consonant is a phone (speech sound) produced by obstructing the air passage with the apex of the tongue (i.e. the tip of the tongue). This contrasts with laminal consonants, which are produced by creating an obstruction with the blade of the tongue (which is just behind

A laminal consonant is a phone produced by obstructing the air passage with the blade of the tongue, which is the flat top front surface just behind the tip of the tongue.

In phonetics, phonation is the "use of the laryngeal system to generate an audible source of acoustic energy, i.e., sound, which can then be modified by the articulatory actions of the rest of the vocal apparatus.

An oral consonant is a consonant sound in speech that is made by allowing air to escape from the mouth. To create an intended oral consonant sound, the entire mouth plays a role in modifying the air's passageway.

A central or medial consonant is a consonant sound that is produced when air flows across the center of the mouth over the tongue.

Examples of central consonants are the voiceless velar plosive (the "k" in the English word "skin"), the voiced alveolar fricative (the

In phonetics, initiation is the action by which an air-flow is created through the vocal tract. Along with articulation, it is one of the two mandatory aspects of sound production: without initiation, there is no sound.

The space between the vocal cords is called the glottis.

Function

As the vocal cords vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing.
