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. This system can handle tasks like checking account balances, making reservations, or providing updates. IVR systems often use pre-recorded messages and voice recognition to guide users through various options. By automating responses, IVR helps businesses manage high call volumes efficiently, improving response times and customer satisfaction while reducing operational costs.
