What is an IVR system used for?

The correct choice is an Interactive Voice Response System, commonly abbreviated as IVR. This technology is widely used in the telecommunication field to allow callers to navigate a phone system before speaking to a live representative.

An IVR system operates by providing pre-recorded voice prompts that guide users through a set of options to help them connect to the appropriate department or access necessary information. This interaction usually involves pressing buttons on the phone keypad or responding verbally to prompts. The primary purpose of an IVR system is to streamline the communication process, reduce wait times, and improve customer service efficiency.

Options like Interactive Voice Recognition, Internet Voice Relay, and Intelligent Voice Response refer to related technologies or concepts but do not accurately define the primary function and structure of an IVR system as it is utilized in most customer service settings.
