Obstruent
(Redirected from Obstruents)
An obstruent (/ˈɒbstruːənt/ OB-stroo-ənt) is a speech sound such as [k], [d͡ʒ], or [f] that is formed by obstructing airflow. Obstruents contrast with sonorants, which have no such obstruction and so resonate.[1] All obstruents are consonants, but sonorants include vowels as well as consonants.
Subclasses
[edit]Obstruents are subdivided into:
- plosives (oral stops), such as [p, t, k, b, d, ɡ], with complete occlusion of the vocal tract, often followed by a release burst;
- fricatives, such as [f, ɸ, θ, s, ʃ, x, v, β, z, ʒ, ɣ], with limited closure, not stopping airflow but making it turbulent;
- affricates, which begin with complete occlusion but then release into a fricative-like release, such as [t͡ʃ] and [d͡ʒ].[2]
Voicing
[edit]Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely phonemically voiceless.[3]
