Client – American Express – IVR (Interactive Voice Response) - Interactive voice response, or IVR, is an automated telephone system technology that enables callers to receive or provide information, or make requests using voice or menu inputs, without speaking to a live agent. IVR is powered by a pre-recorded messaging or text-to-speech technology with a dual-tone multi frequency (DTMF) interface. In American Express we allow card members to leverage both audio and visual experience simultaneously when they call to avail self-servicing in IVR.
