Following the success of the advanced voice response in interacting with callers, industry experts promised the inception of more refined applications which would aid advancement in technology for the world at large in the 1970’s. Fast Forward decades later and the voice response technology suffers major setbacks. It is limited in all facets of development; there have been little or no amount of success recorded in the advancement since its discovery in the 1970’s.  The IVR is a technological system that allows humans route and interact with calls using voice, DTMF tones through the keypad.

Newer technologies have been introduced to the market with striking features:

Keywords, natural recognition and key phrases are the  popular tiers of the IVR speech recognition under a particular supplier; they have been curated to function at any business setting or dealings Direct caller request is the work of the keypad recognition which is also the least sophisticated tier; This tier strives on the correct prognosis by user, if clicking A will get you B, then a user is to follow that circle, if a user defaults, the IVR will refer the user to a main menu function or terminate the whole procedure. The IVR is expectant of a direct compliance to the requested asked for.

Key Phrase recognition; this tier stresses on the use of tag lines, short description that embraces a chain of specific searches. The IVR responds with all related results to the search. If I ask for stores in Abuja, the search results would be looking like;  stores ,Stores in Abuja. Here, its inevitable for communication not to be broken.

The IVR  should observe, articulate the user’s actual plan or request rather than relying on fallible key words

Its a known phenomenon that natural recognition is the  most preferred technology but still as primitive as the years run by. Due to the costly nature of the IVR’s, it is incapable of reaching all heights. New technological breakthrough, using Artificial intelligence generated by IVR technology.

Interactive Voice Response is used to for high call volumes, improves customers experience and reduces cost . It is rich in various spheres like medical sector, surveying and banking.

In the banking sector, the IVR is used as an extension of the 24/7 customer service connection. Meanwhile in the medical scene, the IVR are used by research institutes and pharamacognist make use of the technology. The IVR set the database for filing . In surveying, the IVR is used in many television shows that have the tendency to spark enormous calls and texts.
