short note on plosive
Answers
Plosive consonants are oral sounds, i.e. the soft palate is raised so that air from the lungs cannot pass upwards into the nasal cavity. The air can, therefore, only escape through the oral cavity. All plosives are produced by a complete obstruction of the airflow at some position in the mouth, for example by the lips coming together. Air from the lungs is then compressed behind the temporary obstruction and the air pressure builds up in the mouth. The obstruction is then removed (in this case, by the lips parting) and the air rushes out of the mouth with a slight explosive force, hence the name plosive. Because plosives are made by a complete obstruction that briefly stops the airflow, they are also referred to as stops or stop consonants. Plosives, or stops, occur in pairs and may be produced with or without the vocal folds vibrating. Recall that sounds produced without vocal fold vibration are said to be voiceless. In contrast, sounds produced with vocal fold vibration are said to be voiced. There are three pairs of voiceless-voiced plosives. These are outlined below.
