Obstruent [ 2024-2026 ]

Obstruents frequently occur in pairs—one voiced (vocal folds vibrate) and one voiceless (no vibration)—such as /s/ vs. /z/ or /t/ vs. /d/.

In phonetics, obstruents are divided into three main "flavors" based on how the air is managed: obstruent

An obstruent is a speech sound produced by obstructing airflow in the vocal tract, resulting in a complete or partial blockage that creates noise or friction. Unlike sonorants (such as vowels, nasals, or liquids) which allow air to flow relatively freely, obstruents are defined by their "tight" or "hissy" acoustic properties. Categories of Obstruents In phonetics, obstruents are divided into three main

They produce a significant increase in air pressure inside the mouth compared to the surrounding air. Obstruent vs. Sonorant Obstruent vs

To understand what an obstruent is, it helps to see what it is . In linguistic terms, they are formally marked as [-sonorant] . Obstruents Airflow Restricted or blocked Relatively free Sound Quality Noisy, turbulent Resonant, musical Voicing Often voiceless Prototypically voiced Examples /p, f, tʃ/ /m, l, w, vowels/

They are marked by the presence of noise or silence during the constriction phase.
