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.



Circuit Diagram



Main Component used • AT89S8253 8-bit Microcontroller with 12 Kbyte Flash.

• CM8870 DTMF IC.

•APR 9600 Voice IC.

• Mobile phone.

• 16 x 2 Character LCD.

• 7805 IC.

• Resistor & ceramic capacitor.



PCB Layout



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.



APPLICATIONS-

• Banking & Finance

• Education

• Government

• Telecommunications



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.
