Voiceless Alveolar Sibilant - Features

Features

Features of the voiceless alveolar sibilant:

  • Its manner of articulation is sibilant fricative, which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency turbulence.
  • Its place of passive articulation is alveolar, which means it is articulated with the tongue at the alveolar ridge just behind the gums.
  • Its place of active articulation is usually laminal, meaning that the tongue blade (the part just behind the top) contacts the alveolar ridge, with the tongue tip resting behind the lower front teeth. However, according to Ladefoged and Maddieson, an apical articulation (with the tongue tip touching the alveolar ridge) is also possible, with in fact about an equal number of English speakers using each of the two types.
  • Its phonation is voiceless, which means it is produced without vibrations of the vocal cords. In some languages the vocal cords are actively separated, so it is always voiceless; in others the cords are lax, so that it may take on the voicing of adjacent sounds.
  • It is an oral consonant, which means air is allowed to escape through the mouth only.
  • It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
  • The airstream mechanism is pulmonic, which means it is articulated by pushing air solely with the lungs and diaphragm, as in most sounds.

Famous quotes containing the word features:

    All visible objects, man, are but as pasteboard masks. But in each event—in the living act, the undoubted deed—there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask!
    Herman Melville (1819–1891)

    “It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.”
    Robert Frost (1874–1963)

    However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.
    Andrew Jackson (1767–1845)
