Sonorants are those articulations in which there is only a partial closure or an unimpeded oral or nasal scape of air; such articulations, typically voiced, and frequently frictionless, without noise component, may share many phonetic characteristics with vowels.

The word resonant is sometimes used for these non-turbulent sounds. In this case, the word sonorant may be restricted to non-vocoid resonants; that is, all of the above except vowels and semivowelSemivowel

  often behave like sonorants. The pharyngeal consonant is also a semivowel corresponding to the vowel .

Whereas most obstruents are voiceless, the great majority of sonorants are voiced. It is certainly possible to make voiceless sonorants, but sonorants that are unvoiced occur in only about 5 percent of the world's languages.
