List 3 Characteristic Features Of Stops:
A stop sound is made by creating a blockage of air and then releasing it, consisting of two parts: a closure and a noise burst. These sounds occur in pairs and have distinct acoustic features, such as aspiration and formant frequency changes. Stop sounds cannot be sustained for more than a second and can be distinguished from fricatives.
Stop sounds, also known as plosive sounds, have three characteristic features:
- Closure: Stop sounds are created by completely blocking the airflow in the oral cavity. This closure is then released to produce the sound.
- Noise Burst: When the closure is released, a sudden burst of noise is produced. This noise burst gives stop sounds their characteristic sharp and explosive quality.
- Aspiration: Stop sounds can also be characterized by the presence or absence of aspiration, which is a burst of air that follows the release of the closure. This aspiration is particularly noticeable in aspirated stop sounds like "p," "t," and "k."
These features together make stop sounds distinct from other types of speech sounds.
