Interactive Voice Response (IVR) system


An Interactive Voice Response (IVR) system I

a computerized system that allows a person,

typically a telephone caller, to select an option from

a voice menu and perform transactions with a

computer system. This can be as simple as obtaining

account balances or as complex as performing

sophisticated transactions.

An IVR system plays a pre-recorded voice prompt

and the caller presses a number on a telephone

keypad to select the option, or speaks simple answers

such as yes, no, or numbers in response to the

voice prompts.

Database Systems Corp. (DSC) is a leading provider

of computer telephony integration products including

automated call answering services and IVR phone

systems. DSC turnkey IVR systems are composed of

Intel processors with embedded Windows OS from

Microsoft Corporation. These systems also include

Dialogic computer telephony boards.

DSC also provides complete Windows IVR software

that lets you develop your own call answering

applications. DSC can likewise perform custom ivr

application development for you. From simple to

complex phone applications, DSC personnel can

design, develop, test and implement your phone

campaign quickly and have your phone program in

place with a minimal amount of time

IVR Voice Messaging

IVR Applications Using Voice XML

IVR Voice XML Application


Database Systems Corp. (DSC) is a leading

provider of computer telephony products

including interactive voice response solutions

using XML and VXML technology.

What Is IVR and VXML?

VoiceXML (VXML) is a format for

specifying interactive voice dialogues

between a human and a computer. This

standard allows IVR and voice applications

to be developed and deployed in a way

similar to how HTML is used for web

applications. Systems employing this

technology are sometimes referred to as

Voice Portals.

A common implementation is to deploy

banks of voice browsers attached to the

public switched telephone network so that

users can use a telephone to interact with

voice applications.

Our phone messaging services with VXML

messaging lets you automatically send phone

messages from your computer system to our phone

systems using VoiceXML Push logic. Our phone

systems can automatically access information from

your computer systems and web servers using XML

pull logic, retrieving web information and converting

this to voice.

Alerts can be automatically broadcast to systems

administrators or to an entire department based upon

an external event such as a power failure or system

failure. Other applications may be as simple as

wakeup calls or weather alerts that are triggered

automatically from your own computer systems or

messaging systems.

XML Pull Data Access

Database Systems Corp. supports XML Pull and Web

Information Access logic that enables our PACER

phone system to make external requests for

information via the internet. Using this technique,

callers can be given information maintained

anywhere on the web. Using our Text To Speech

application software, text information can be

retrieved via discreet messages to other web sites (or

servers) and this information converted into a phone

message that is automatically played to the caller.

Virtually any type of information can now be relayed

to a caller using our phone system.

Arlington Transit

ART - Arlington Transit operates within

Arlington County, Virginia,

supplementing Metrobus with smaller,

neighborhood-friendly vehicles and

providing access to Metrorail and Virginia

Railway Express (VRE). Most of ARTâ„¢s

state-of-the ART buses operate on cleanburning

natural gas; all have climate

control to keep you comfortable and

dependable schedules to keep you on

time. -

ART uses our IVR application

technology including XML push to assist

commuters waiting for bus service.

While waiting for bus service, callers can

use their cell phone to call an 800

number published at a bus stop. They

enter the bus stop number on the phone

keypad and our service sends a query to

a central dispatch website retrieving

information about the next bus to arrive

at this particular stop. Data is pushed to

our phone system using VXML protocal

and is converted using our text to speech

program. This message in turn is played

to the caller, giving them the

approximate time of the next bus arrival.

What Is IVR?

Interactive voice response, or IVR, is a

computerized phone system that enables

a person, typically a telephone caller, to

make a selection from a voice menu. The

selection is made using touchphone

keypad entries or voice responses. This

interaction allows the individual to

communicate with the phone system and

thus the computer system.

The phone system plays pre-recorded

voice prompts and the person typically

presses a number on a telephone keypad

to select the option associated with the

voice prompt.

DSC provides the following interactive voice

response solutions:

· IVR Systems - Complete analog and

digital IVR phone systems.

· IVR Software - IVR application

development software solutions.

information within IVR programs.

DSC IVR solutions utilize Intel processors and

contain Dialogic IVR telephony boards. These

solutions provide callers with the ability to

automatically obtain information or perform

transactions using a phone system.

IVRS (interactive voice response systems) use

voice recorded prompts and menus to present

information to callers. Touch-tone telephone

keypad entries are gathered from the caller to

collect information and to provide user

navigation. Information is delivered to the caller

using text to speech or pre-recorded responses.

This information can be obtained locally from

internal databases or remotely through the

internet. (IVR and VXML Data Access).

Interactive Voice Response (IVR) Systems

 Interactive Voice Response (IVR) systems have become more complex and more prevalent.
 Information can be accessed and processed over the phone through touch tone and speech user interfaces.
 The speech component allows customers to use verbal commands to obtain general or personal (account) information and conduct transactions.
 Providing an intuitive user interface is key for a successful user experience.
Fidelity’s Phone Stats
 Fidelity’s phone systems receive a combined average of 282,000 phone calls per day.
 Forty-two percent of those calls are handled by an automated system.
 Fidelity has conducted a great deal of research into older adult’s usage of the web.
 We observed many age-dependent behaviors that affected web usage.
 Would we see similar results if we looked at our IVR system?
Our Usability Studies
 We have conducted over 125 IVR-based usability and research sessions over the past 5 years, many with older adults.
 The studies included several “typical” usability sessions (approx. 8-10 users) and one larger research study that specifically focused on older users.
 The systems tested were designed to:
 Find account and personal information
 Conduct transactions
 Report technical problems
 Check voicemail
 Set up a voice ID
 Most systems used both speech recognition and touch tone interfaces.
Research Study Results
• Task Completion Rate by Age Group
(p = .037, n=27)
Designing for the Older User
 Older users bring different abilities and expectations to phone-based interactions than younger users do.
 Until the middle of 2004, 96% of users interacted primarily through touchtone.
Lessons Learned
 We compiled the following lessons learned from the variety of usability studies we conducted over the past few years with older adults.
 Our recommendations are based on our past experience and other available research.
Don’t set false expectations
 Unrealistic expectations of system’s abilities (Expecting a ‘Star Trek’ experience).
 Users knew they weren’t talking to people, but many older adults tried to interact with the system as if it were human.
 The conversational and easy-going “nature” of some interfaces may set false expectations.
 Some users described certain system responses, such as “Got it,” as colloquial and not professional.
 “Younger users expressed annoyance at the system attempting to sound sorry.
Be Consistent
 Consistency is very important.
 Sudden auditory changes of the automated voice might signal an error or incorrectly indicate that users have been transferred somewhere else.
 Menu structure and controls should be consistent throughout the interaction. Don’t set up the ability to use voice commands in one part of the system and then disable voice commands in other parts of the system.
Pacing of System
 Pace of system was often too fast for older users.
 Older users tend to be slower at information processing.
 Providing them just enough time between spoken menu items to echo each choice sub-vocally appears to improve their success with IVR Systems.
 However, some younger users actually preferred menu items spoken at a more rapid pace (less time between items) as they could get to the information they wanted faster.
 Pace of system was often too fast for older users.
 If possible, consider implementing a system that recognizes the age of the user and leverages that to determine the amount of space between items and the speed at which the menu prompts are spoken.
 If that is not possible, we recommend following the option that would help the greatest number of users, i.e. the largest user group.
Avoid Information Overload
 Too many menu choices & long messages
 Reduced working memory capacity in older users made this more problematic for them than younger users.
 When presented with a long menu, we observed many older users simply choosing the last item in the list.
 Lengthy messages can also overload memory. We observed a a few older users opting out to a representative possibly because it took too long to get to the menu prompts.
Avoid Jargon
 Usage of jargon, obscure terminology
 This affected all users, but especially older users and those with lower levels of financial literacy.
 If users are unsure what a menu prompt means, they will be more likely to just make a random choice or attempt to reach a representative quickly.
 Know your users and avoid using “jargon-y” terms that they may not understand.
 Using familiar words & ones that refer to concrete objects has been shown to improve performance.
 Older users were overly polite.
 Older users were often hesitant and had trouble interrupting the system.
 They often said “please” and “thank you”.
 They spent much longer on the phone at the end of the call than younger users because they waited for an obvious ‘out’ vs. just hanging up.
 Allow generous barge-in.
 The system should ignore various pleasantries such as “please
and “thank you”.
 Inform users at various points in the interaction that they can hang up when they’re finished.
Include Some Touchtone Options
 Many users prefer using the touchtone options to speaking their choices.
 Always offer a touchtone option for entering sensitive information, like SSN and PIN.
 Touchtone options serve as an external memory device, offering a physical indication of the available choices (think of a finger hovering over buttons). This seemed especially helpful to older users.
 Use touchtone options strategically when transitioning users into a new technology
 In the initial rollout, offer both touchtone and voice options in the first menu.
 Touchtone options should always be available as a backup.
► Accents, environments, privacy concerns.
Frequency of Sound
 Because higher-frequency sounds are the first to go with progressive hearing loss1, use a lower-pitched voice.
 Peak hearing sensitivity is around 3,000 – 4,000 Hz.
 Lower frequencies are less susceptible to ‘masking’ effects
Positive Reaction to Voice Recognition
 Many seniors were very enthusiastic about the voice recognition.
 Hands-free interaction helps users:
 With physical impairments such as arthritis
 Fine motor-control problems
 On cell and cordless phone
 “Words are much easier!” – comment from a user with severe arthritis.
 Many of the usability issues we observed affected both older and younger people, but in general older users had more trouble recovering from those errors.
 Many of the usability recommendations given here would benefit all users if implemented.
 Understanding issues that result from the aging process help not only older users but lead to a more universally accessible design.
The key is to know and design for your user.
 If the majority of users is older make sure your system accommodates their requirements.
 Set expectations. Warn customers of big changes – ahead of time and/or in the system itself.

What can be done using an Inter voice System?

When connecting an Inter-voice system into telephone lines (either analog lines or digital T1/E1 trunks), the applications can handle either incoming or outgoing calls and then perform the following voice processing features:
• Provides unlimited pre- recorded voice messages
• Live recording of customer messages
• Accesses or stores information to and from the back-end host, database or the Internet
• Uses leading speech recognition technology to process either spoken words or full Sentences.
Who should use Inter voice?
Using Inter voice hardware and software, we have developed voice automation applications, which can:
• Transfer the customer calls to the right people to handle
• Provide the most updated product or service information
• Record customer messages for follow up later
• Perform automated transaction processing without human intervention.
What are interactive voice response (IVR) systems?
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. IVR systems allow the user to efficiently exchange information, reducing clerical processing.
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 responses made.
What are important features of IVR systems?
IVR system should store responses made by callers. Should be able to provide different responses to callers based on time of day called. Should be able to capture either touch-tone or voice responses by callers.
1.1 Aim Of The Project
We have decided to choose this topic “IVRS” because
• IVRS is a Acronym for Intelligent Voice Response System
• The system used is Intelligent for Interaction
• 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 So we have decided it to implement this system for educational purpose i.e. marks enrollment.
CALL centres originated as a cost-cutting measure by US companies several decades ago, but they only really started to take off in the UK in the 1970s. The initial centres were in-house operations in larger organizations and they tended to share and be formed by the same basic assumptions and drivers. The idea was that if you could cluster the majority of telephone based contacts with the customer in a single department you could have people focused just on call-related services. Several advantages would follow. First, as a coherent department focused on telephone services, such a ‘centre’ could be managed more coherently. A second motive was that through careful management of the centre, you would inevitably get the benefit of having more calls handled by fewer people. Steve Morrell, Managing Director at Contact Babel, an organization that specializes in analyzing the call centre market, points out that this early focus on ‘efficiency’ and cost cutting, in a sense, got the call centre industry started off on the wrong foot - at least in relation to current ‘best practice’ "It meant that the whole industry focused on measuring things such as call lengths, or time to resolution. The faster the operator could complete a call, the more efficient and effective the contact with the customer was deemed to be," he explains. Divide the number of calls by the number of operators, and you could see at a glance how ‘efficiently’ your centre was operating.
The bigger the number, the better. The shorter the call duration and the shorter the time to resolution, the better. There were obvious problems with this approach. First, it led to a ‘sweat the agent’ attitude, since the pressure was on to set call centre agents more and more ‘stretching’ targets by way of calls per hour that they were supposed to complete. Second, it led to a high turnover in staff as people became burned out by the pressure cooker atmosphere.
Since the costs of training a call centre agent are not trivial (Morrell puts them at around £6,000 per agent on average), a high staff turnover leads to high costs. A third issue, which took rather longer for companies to grasp, was that agents were not being given the opportunity to learn very much about the customer, or to add much value to the customer’s relationship with the organization. In fact in many instances an emphasis on keeping call times as brief as possible would actually cause the agent, at best, to sound impersonal and unsympathetic to the customer. At worst the experience would be decidedly unsatisfactory and would possibly do lasting damage to the company’s brand and reputation in the customer’s eyes.
Morrell points out that call centres were given a huge boost in the UK in the 1980s when telecoms deregulation led to a fall in the price of fixed line calls. Channeling contact to the customer through the telephone became an even more cost effective option for companies. Since the UK led the way in telecoms deregulation in Europe, this was a major factor in the UK having more call centre seats than any country with the exception of the US. We currently have in excess of 800,000 call centre places across currently have in excess of 800,000 call centre places across the UK, and the number is project and implimentationed to go beyond 1,000,000 within the next three years.
Colin Mackay, a Director of the industry body, the Call Centre Managers Association (CCMA), points out that pioneering centre set up by Direct Line and then by First Direct, proved how powerful these centres could be for financial services organizations. "It meant that they could reach large numbers of the public without the requirement for sales people on the street," he said.
As Mackay notes, about 80% of the questions that people have about financial services products, from mortgages to loans and insurance, can be answered over the phone, without the need for a face-to-face meeting. Operations such as Direct Line were able to demonstrate considerable cost savings and efficiencies over conventional financial services product distribution strategies. Scotland and the north-east of England did very well out of the first two decades of call centre operations in the UK. As Mackay explains, call centre operators tended to favour regions outside the expensive south-east of England, where building premises were far cheaper, and where there was a reasonably well-educated potential work force. The fact that the north-east of England and Scotland had seen a massive decline in their heavy industries meant that there was also competitive pressure for jobs, so wages were more competitive too, than down south.

Interactive Voice Response System


To Integrate Interactive Voice Response System with the present Indian Telecom Network. The goal design of any IVR system should be to get the customer what he or she needs in as few steps as possible while allowing for security and logistical needs.

Technical Details:

Microsoft Visual studio C++

Innovativeness and usefulness:

Interactive voice response (IVR) is a technology that allows a computer to interact with humans through the use of voice to address these requirements Interactive changed number announcement, Interactive telephone bill enquiry system, Interactive fault reporting system, Interactive commercial information & special service assistance, Interactive telephone fault clearance system, Automatic bulk number change announcement, Automatic payment reminder, Any other generic application.

Brief Overview:

My paper will try to provide a framework on how to think about Interactive Voice Response System works and its application to a organization. The telephone number change can occur not only due to the area transfer or the exchange numbering scheme fine but also due to the subscriber’s request .Thus there is a necessity of a system wherein the Department will be able to inform any subscriber querying on old telephone number about the new telephone number. This will help the subscriber to easily find the correct telephone number of the customer whom he wants to contact quickly. So is the application of bill enquiry system, Interactive fault reporting system, Interactive commercial information & special service assistance, Interactive telephone fault clearance system, Automatic bulk number change announcement, Automatic payment reminder.

Scope of Work:

Interactive Voice Response System has been a key enabler to automatic bill enquiry system, bulk charge number announcement system, change number announcement system, commercial information system, fault reporting system, payment reminder system.
Nevertheless, the path to interactive voice response system is far from trivial. The deployment of services based on IVRS will not be an easy task and a few daunting issues are to be faced in several aspects, including manageability, scalability and reliability.
This paper will focus on the services of interactive voice response system and try to provide a broad overview of the main challenges ahead.

Interactive Voice Response (IVR) System

.doc   Interactive Voice.doc (Size: 132 KB / Downloads: 22)


The Interactive Voice Response (IVR) System serves as a bridge between people and computer databases by connecting the telephone network with the database. The telephone user can access the information from anywhere at anytime simply by dialing a specified number and following an on-line instruction when a connection has been established. The IVR system uses pre-recorded generated voice responses to provide information in response to an input from a telephone caller. The input may be given by means of touch-tone or Dual Tone Multi-Frequency (DTMF) signal, which is generated when a caller presses a key of his/her telephone set, and the sequence of messages to be played is determined dynamically according to an internal menu structure (maintained within the IVR application program) and the user input. The IVRS system which will be designed will provide an ideal platform for the operation of start-ups and existing small concerns. It will be a highly economical and efficient way to replace the Dialogic card which is very costly and requires a high maintenance and regular up gradation.

DTMF Transmitter:

Mobile is based on DTMF Technology. When you press a button of mobile keypad, a connection is made that generates a resultant signal of two tones at the same time. These two tones are taken from a row frequency and a column frequency. The resultant frequency signal is called "Dual Tone Multiple Frequency". These tones are identical and unique.
A DTMF signal is the algebraic sum of two different audio frequencies, one from low frequency group and other from high frequency group.
Each of the low and high frequency groups comprise four frequencies from the various keys present on the telephone keypad; two different frequencies, one from the high frequency group and another from the low frequency group are used to produce a DTMF signal to represent the pressed key.
When you send these DTMF signals to the telephone exchange through cables, the servers in the telephone exchange identifies these signals and makes the connection to the person you are calling.

Voice Processor:

As shown this circuit has three pushbuttons: one for recording, one for playback on edge detection and one for playback on level detection. Since we don't have three pushbuttons in our lab kit, we will use simple wire bridges to simulate the buttons (to simulate a pushed button we connect the wire bridge to ground). The recording button does exactly what it says: pushing it allows you to record sound. Releasing the button stops the recording.
If the end of memory (EOM) of the chip is reached before the button is released, the chip will automatically terminate the recording and go to the power down mode. There is also a red recording indicator LED. This LED lights up when you record sounds. Sounds can be recorded in two different ways: using the microphone as seen in the above circuit example - or using a direct input from e.g. your stereo system's cd-player which is connected to ISD1720's analog input pin. Unfortunately, this is quite tricky - the following application note shows you why. In most cases, if you want to record CD sound, holding the microphone close to your stereo's speaker will be a faster solution with only a little quality payoff.

Microcontroller and EEPROM

Microcontroller Logic: The function of microcontroller is to control input output based on the programmed embedded hex logic. The microcontroller continuously scans input logic. The input logic is BCD data from 9170 and keypad. The BCD data is used in voting mode while keypad data is used in administrative mode for checking total number of vote for corresponding party.
Let us consider a case at the transmitter mobile I have pressed number 2, thus at receiver side 9170 generate corresponding BCD logic 0010. The microcontroller receive 0010 at pin no 1,2,3,4. The microcontroller is programmed if input is 0010, go to check password.

User mode

In user mode microcontroller is programmed to continuously scan portb input coming from mobile phone. If some user is using first of all he has to make a call to the ivrs number, ivrs automatically receive the call and start voice processor to announce instruction. Then he has to enter roll number. The microcontroller confirms that given roll number is using first time. If is first time voice processor announce enter
