Interactive voice response (IVR) is a technology that allows computers to interact with humans through voice and keypad inputs. IVR systems are used in a wide variety of applications, including customer service, technical support, and information retrieval.
IVR systems can be simple or complex. Simple IVR systems may only offer a few basic options, such as directing callers to the appropriate department or playing a recorded message. More complex IVR systems may offer a wide range of options, including self-service features that allow callers to resolve their own issues without speaking to a live agent.
