What is an example of a continuous sound?

A continuous sound is characterized by the ability to produce it without interruption, allowing for a prolonged voicing of the sound. In this context, the /m/ sound is an example of a continuous sound because it is produced with the vocal cords vibrating while the mouth is closed, enabling the sound to be sustained for as long as breath is available. This contrasts with sounds like /p/, /t/, and /k/, which are classified as stop consonants. These stop sounds require a complete closure of the vocal tract during their articulation, causing them to be released suddenly and making them non-continuous. Therefore, the /m/ sound is the correct choice as it represents a sound that can be elongated, illustrating the concept of continuous sounds effectively.
