This page contains phonetic information in IPA, which may not display correctly in some browsers.

Each spoken consonant can be distinguished by several phonetic features:

  • The manner of articulation is how air escapes from the vocal tract when the consonant or approximant (vowel-like) sound is made. Manners include stops, fricatives, and nasals.
  • The place of articulation is where in the vocal tract the obstruction of the consonant occurs, and which speech organs are involved. Places include bilabial (both lips), alveolar (tongue against the gum ridge), and velar (tongue against soft palate). In addition, there may be a simultaneous narrowing at another place of articulation, such as palatalisation or pharyngealisation.
  • The phonation of a consonant is how the vocal cords vibrate during the articulation. When the vocal cords vibrate fully, the consonant is called voiced; when they do not vibrate at all, it is voiceless.
  • The voice onset time (VOT) indicates the timing of the phonation. Aspiration is a feature of VOT.
  • The airstream mechanism is how the air moving through the vocal tract is powered. Most languages have exclusively pulmonic egressive consonants, which use the lungs and diaphragm, but ejectives, clicks, and implosives use different mechanisms.
  • The length is how long the obstruction of a consonant lasts. This feature is borderline distinctive in English, as in "wholly" vs. "holy", but cases are limited to morpheme boundaries. Unrelated roots are differentiated in various languages such as Italian, Japanese, and Finnish, with two length levels, "single" and "geminate". Estonian and some Sami languages have three phonemic lengths: short, geminate, and long geminate, although the distinction between the geminate and overlong geminate includes suprasegmental features.
  • The articulatory force is how much muscular energy is involved. This has been proposed many times, but no distinction relying exclusively on force has ever been demonstrated.

All English consonants can be classified by a combination of these features, such as "voiceless alveolar stop" . In this case, the airstream mechanism is omitted.

Some pairs of consonants like p::b, t::d are sometimes called fortis and lenis, but this is a phonological rather than phonetic distinction.

Consonants are scheduled by their features in a number of IPA charts:

Famous quotes containing the word features:

    “Art is the child of Nature; yes,
    Her darling child, in whom we trace
    The features of the mother’s face,
    Her aspect and her attitude.”
    —Henry Wadsworth Longfellow (1807–1882)

    “The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
    —Marcel Proust (1871–1922)

    “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)
