Overview

In phonetics the place of articulation identifies the location in the vocal tract where a consonant (or some vowels' secondary quality) is produced. It is one of the key properties that distinguish speech sounds: together with manner of articulation and voicing, place helps define each consonant phoneme in a language. For a general introduction see phonetics or the study of human speech sounds at speech science resources.

Primary articulators and categories

Articulatory descriptions contrast the active articulator (usually some part of the tongue or the lips) with the passive place (teeth, alveolar ridge, hard palate, velum, uvula, pharynx, or glottis). Phoneticians often group places into four broad families: labial (lips), coronal (tongue tip or blade against front parts of the mouth), dorsal (tongue body against the palate or velum), and laryngeal (glottal and pharyngeal regions).

Common places of articulation

  • Bilabial (both lips)
  • Labiodental (lower lip and upper teeth)
  • Dental / interdental (tongue against or between the teeth)
  • Alveolar (tongue against the alveolar ridge)
  • Postalveolar
  • Retroflex (tongue tip curled back)
  • Alveolo-palatal
  • Palatal (tongue body against hard palate)
  • Velar (tongue body against the soft palate)
  • Labiovelar (simultaneous labial and velar contact)
  • Uvular
  • Pharyngeal
  • Glottal (vocal folds)

Examples and linguistic importance

Languages differ in which places they use contrastively. For example, English contrasts bilabial /p, b, m/, labiodental /f, v/, alveolar /t, d, s, n/, postalveolar /ʃ/, palatal /j/ and velar /k, g, ŋ/; other languages add uvulars, pharyngeals, or a series of retroflex sounds. Place of articulation affects phonotactics, allophony, and accent traits; it also shapes acoustic cues that listeners use to identify consonants.

History, analysis and notable points

Interest in articulatory places goes back to classical and medieval grammarians and was developed systematically in modern linguistics and experimental phonetics. Descriptions combine observation, palatography, and instrumental methods (like spectrography and articulatory imaging). Some sound types, such as clicks or ejectives, involve different airstream mechanisms and are classified alongside places of articulation but require additional notation; secondary articulations such as palatalization, labialization, and velarization add simultaneous place-like quality to a consonant.

Distinctions to remember

Place of articulation is distinct from manner (how air is shaped or blocked) and voicing (vocal fold vibration). Accurate identification of place is central for phonetic transcription, language description, speech therapy, and technologies such as speech synthesis and recognition.
