A voice message is a recorded verbal communication left by one person for another. It typically involves speaking into a device such as a telephone or smartphone, and recording a brief message that can be played back at a later time. Voice messages are often used when someone is unavailable to take a call, allowing the caller to leave information or a greeting without having to wait on hold. They can also serve as a convenient way for people to communicate with each other, especially in situations where it may not be possible to have a live conversation.
