What are plosive sounds?

• A. Sounds produced with continuous airflow
• B. Sounds that are produced at a constant pitch
• C. Consonant sounds produced by blocking and releasing airflow
• D. Vowel sounds made with the mouth wide open

Answer: (C)

Plosive sounds are indeed consonant sounds that are produced by momentarily blocking the airflow in the vocal tract and then releasing it suddenly. This process creates a burst of sound, hence the term "plosive." For example, sounds like /p/, /b/, /t/, and /d/ are classic examples of plosives. In each case, the airflow is stopped for a brief moment, creating a build-up of pressure, and is then released, producing the characteristic explosive sound of these consonants.

The other options do not accurately describe plosive sounds. Continuous airflow describes fricative sounds, while constant pitch pertains more to voicing or tonal qualities rather than being specific to the articulation of consonants like plosives. Lastly, vowel sounds produced with the mouth wide open focus on a completely different aspect of speech production that does not relate to the manner of articulation that plosives exhibit. Understanding these elements helps clarify the distinct nature of plosive sounds within speech science.
