Interactive Voice Response (IVR) systems
allow callers to interact with the
communications system over the telephone.
IVR is used to enable the caller to retrieve
information from a database, enter
information into a database, or both.

How It Works?
An IVR system talks to callers following a
recorded script. It prompts a response to the
caller and asks him to respond either verbally or
by pressing a touchtone key, and supplies the
caller with information based on responsesmade.

PROJECT OBJECTIVE
• DTMF decoding is used to interpret the caller's
response to voice prompts.
• DTMF tones are entered via the telephone
keypad.
• Micro-controller plays the message according
to DTMF code and answer through Mobile.
• LCD displays coding generated by DTMF

AIM OF THE PROJECT
• IVRS is a Acronym for Intelligent Voice
Response System.
• Will consider the nature of the user, to provide
the correct response.
• And will provide the user with all sorts of
related information for his concern.

Progress
• We have made a modification by using
cellphone in place of SIM 300 module due to
complex data sheet and its high cost although
performance will be same.
• In voice IC circuit we will record our voice
message.
• We are working on the programming section
and logic side by side.
• We have made the PCB layout of our circuit.

ADVANTAGES
• The biggest advantage of IVR for small and largeorganizations is to save time and money
• IVR systems can take care of most of the frequently askedquestions that an organization receives
• If a large company is able to save even a second off theaverage length of each phone call with a live operator, itcan save them hundreds of thousands or even millions of dollars a year
• IVR systems have the advantage of making callers andcustomers feel like they're being attended to, even if it's just by a machine.

LIMITATIONS-
• The only disadvantage of IVR systems is that
many people simply dislike talking to
machines.
• Older adults may have a hard time following
telephone menus and lengthy instructions.
And younger callers get frustrated with the
slowness of multiple phone menus.
