plosív

Plosiv is a term used in phonetics and linguistics to describe a consonant sound produced by stopping the airflow in the vocal tract and then releasing it suddenly. These sounds are also known as stops or occlusives. The production of a plosive involves three main stages: closure, where the airflow is completely blocked; release, where the blockage is removed; and aspiration, which is a brief puff of air that may follow the release.

Plosives are classified by the place of articulation, which is where the airflow is blocked, and by the manner of articulation, which describes how the airflow is released. Common places of articulation include the lips (bilabial), the alveolar ridge (alveolar), and the velum (velar). The manner of articulation for plosives is always a complete closure followed by a sudden release.

In many languages, plosives can be either voiced or voiceless. Voiced plosives are produced with vibration of the vocal cords, while voiceless plosives are produced without vocal cord vibration. For example, in English, the 'p' in "pin" is a voiceless bilabial plosive, while the 'b' in "bin" is a voiced bilabial plosive. Similarly, 't' and 'd' are alveolar plosives, and 'k' and 'g' are velar plosives. The presence or absence of voicing can distinguish words in many languages, making plosives crucial for phonetic distinctions.
