Definition

What is it?

A voice recorder is a device or an app that captures and saves sounds, especially human voices. It turns spoken words into an audio file that you can listen to later. Think of it like taking a photo, but for sounds instead of pictures.

Simple Example

Quick Example

Imagine your cricket coach is explaining a new strategy for fielding. Instead of trying to write everything down quickly, you can use a voice recorder on your phone to record his instructions. Later, you can listen to the recording again to remember all the important points and practice better.
