'''Interactive voice response''' ('''IVR''') is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and [[dual-tone multi-frequency signaling|DTMF]] tones input with a keypad. In [[telephony]], IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be inquired about through the IVR dialogue. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling as IVR systems are more intelligent than many [[predictive dialer]] systems.<ref>{{Cite web|url=https://thenextweb.com/future-of-communications/2015/04/20/enhancing-customer-engagement-with-interactive-voice-response/#gref|title=Enhancing customer engagement with interactive voice response|publisher=The Next Web|author=Tolentino, Jamie|date=20 April 2015 }}</ref>

IVR systems can be used to create self-service solutions for mobile purchases, banking payments, services, retail orders, utilities, travel information and weather conditions. In combination with systems such an [[automated attendant]] and [[automatic call distributor]] (ACD), call routing can be optimized for a better caller experience and workforce efficiency. IVR systems are often combined with automated attendant functionality. The term '''voice response unit''' ('''VRU''') is sometimes used as well.<ref>{{cite book | isbn=9780471216667 | title=Implementing Voice Over IP | first=Bhumip | last=Khasnabish | location=Lexington, Massachusetts, USA | url=https://books.google.com/books?id=Nmbexusn9q4C&q=vru+ivr&pg=PA203 | publisher=John Wiley & Sons, Inc.| page=203 | access-date=21 March 2012 | date=2003-05-30}}</ref>
