Voiceless alveolo-palatal fricative

Features

• Its manner of articulation
  Manner of articulation
  In linguistics , manner of articulation describes how the tongue, lips, jaw, and other speech organs are involved in making a sound make contact. Often the concept is only used for the production of consonants...
  
   is sibilant
  Sibilant consonant
  A sibilant is a type of fricative or affricate consonant, made by directing a jet of air through a narrow channel in the vocal tract towards the sharp edge of the teeth.-The term:...
  
   fricative
  Fricative consonant
  Fricatives are consonants produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of ; the back of the tongue against the soft palate, in the case of German , the final consonant of Bach; or...
  
  : 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
  Turbulence
  In fluid dynamics, turbulence or turbulent flow is a fluid 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. Flow that is not turbulent is called laminar flow...

• Its place of articulation
  Place of articulation
  In articulatory phonetics, the place of articulation of a consonant is the point of contact, where an obstruction occurs in the vocal tract between an active articulator and a passive articulator...
  
   is alveolo-palatal
  Alveolo-palatal consonant
  In phonetics, alveolo-palatal consonants are palatalized postalveolar fricatives, articulated with the blade of the tongue behind the alveolar ridge, and the body of the tongue raised toward the palate...
  
   (palatalized
  Palatalization
  Palatalization or palatalisation generally refers to two phenomena:*As a process or the result of a process, the effect that front vowels and the palatal approximant frequently have on consonants;...
  
   laminal
  Laminal consonant
  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 on the top. This contrasts with apical consonants, which are produced by creating an obstruction with the tongue apex only...
  
   postalveolar
  Postalveolar consonant
  Postalveolar consonants are consonants articulated with the tongue near or touching the back of the alveolar ridge, further back in the mouth than the alveolar consonants, which are at the ridge itself, but not as far back as the hard palate .Among the fricatives and affricates, a subtype called...
  
  ): it is articulated with the front of the tongue
  Tongue
  The tongue is a muscle on the floor of the mouth that manipulates food for chewing and swallowing . It is the primary organ of taste, as much of the upper surface of the tongue is covered in papillae and taste buds. A secondary function of the tongue is speech, in which the organ assists...
  
   behind the alveolar ridge
  Alveolar ridge
  An alveolar ridge 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 of the teeth.They can be felt with the tongue in the area right above the top...
  
  , and the body (middle) of the tongue raised toward the palate
  Palate
  The palate is the roof of the mouth in humans and vertebrate animals. It separates the oral cavity from the nasal cavity. The palate is divided into two parts, the anterior bony hard palate, and the posterior fleshy soft palate or velum...
  
  .
• Its phonation
  Phonation
  Phonation has slightly different meanings depending on the subfield of phonetics. 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...
  
   type is voiceless: it is produced without vibrations of the vocal cords.
• It is an oral consonant
  Oral consonant
  An oral consonant is a consonant sound in speech that is made by allowing air to escape from the mouth, as opposed to the nose. To create an intended oral consonant sound, the entire mouth plays a role in modifying the air's passageway. This rapid modification of the air passageway using the tongue...
  
  : air is allowed to escape through the mouth.
• It is a central consonant
  Central consonant
  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 voiced alveolar fricative and the alveolar nasal .A consonant in which air...
  
  : it is produced by allowing the airstream to flow over the middle of the tongue, rather than the sides.
• The airstream mechanism
  Airstream mechanism
  In phonetics, the airstream mechanism is the method by which airflow is created in the vocal tract. Along with phonation, it is one of two mandatory aspects of sound production; without these, there can be no speech sound....
  
   is pulmonic egressive: it is articulated by pushing air out of the lung
  Lung
  The lung or pulmonary system is the essential respiration organ in air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart...
  
  s and through the vocal tract, rather than from the glottis
  Glottis
  The glottis is defined as the combination of the vocal folds and the space in between the folds .-Function:As the vocal folds vibrate, the resulting vibration produces a "buzzing" quality to the speech, called voice or voicing or pronunciation.Sound production involving only the glottis is called...
  
   or the mouth.
