Interactive Voice Response (IVR) is a technology that allows users to interact with a computer system through voice or keypad inputs. It is commonly used in customer service settings, enabling callers to navigate menus and access information without needing to speak to a human representative. IVR systems can handle various tasks, such as checking account balances, making reservations, or providing technical support. By automating these processes, IVR helps businesses improve efficiency and reduce wait times for customers, making it a valuable tool in modern communication.
