Template:Short description An obstruent (Template:IPAc-en Template:Respell) is a speech sound such as Template:IPAblink, Template:IPAblink, or Template:IPAblink 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
Obstruents are subdivided into:
- plosives (oral stops), such as Script error: No such module "IPA"., with complete occlusion of the vocal tract, often followed by a release burst;
- fricatives, such as Script error: No such module "IPA"., 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 Script error: No such module "IPA"..[2]
Voicing
Obstruents are often prototypically voiceless, but voiced obstruents are common. This contrasts with sonorants, which are prototypically voiced and only rarely phonemically voiceless.[3]
