Interactive Voice Response (IVR) is a technology that allows a computer system to interact with humans using DTMF tones input from a connected phone call's keypad. An IVR system is now a basic necessity for handling large call volumes or filtering out calls to be routed to the correct departments in a call centre. With Text-to-Speech (TTS) features, modern IVRs can dynamically interact with humans, following inputs from their phone's keypads. IVRs are widely used to direct calls to the appropriate departments, let callers select preferred languages before interacting with an agent, and facilitate order bookings based on a predefined menu. Thus, it is an effective way to automate the communication of certain information that has to be repeated every time a customer calls or tries to connect in respect of some issues or problems.
