1. Introduction

1.1 Purpose


Voice Based Web Browser. voice-based web to make information accessible to
users who may not be able to read or write, or who do not have access to the Internet.
Users can access the voice-based web using a toll-free number, through a variety of
ways including a voice recognition system or a tone phone. Unlike a computer
interface, a voice interface needs no keyboard, no mouse, no screen, freeing users
from these barriers to access and action. It requires no training. It is accessible to
anyone with a telephone. Voice is mobile—information can be sent and retrieved
from anywhere. Since customers can have access at anytime from anywhere, voice
makes it possible to use time more effectively. Fast and efficient, voice frees users
from not only the desktop, but even the laptop.

1.2 Scope
 The user gives the request through the voice or text using phone ,personal
computer or Touch tone.

 The request goes to the voice browser.If the request is voice, speech
recognition converts voice into text.

 Checks the grammers and then using speech synthesis to convert text into
pre-recorded audio.

 The pre-recored audio should be store in the administrator.it should display
to the user.

1.3. Definitions, Acronyms and Abbreviations

• ADMIN-Administrator has the authority for convert the voice into
text,text into voice and then displaying to the user.

• ASR-Automatic Speech Recognition is to convert the speech into text.

• HTML – Hypertext Markup Language is to create static websites.

• J2EE – Java 2 Enterprise Edition is a programming platform and it is the part
of the java platform for developing and running distributed java applications.

• EJB – Enterprise java bean, it is architecture for the development and
deployment of transactional, distributed object applications-based, server-
side software componen



• RSA – Rational Software Architect is a designer toolkit which is
designed for develop more complex projects by providing fully dynamic
web service.

• DB2 – Database 2 is the database management system that provides a
flexible and efficient database platform to erect strong on demand
business applications.

• UML- Unified Modeling Language is a standard language for writing
software blueprints. The UML may be used to visualize, specify,
construct and document

• XML - Extensive Markup Language used for data transfer and XML is
stored naturally in DB2

• HTTP – Hypertext transfer protocol is a transaction oriented client/server
protocol between web browser and a web server.

• HTTPS – Secure hypertext transfer protocol is a hypertext transfer
protocol over secure socket layer.

1.4 Technologies used:

 HTML – Hyper Text Markup Language

 Java Script – Script Language

 XML – Extensive Mark Up Language

1.7 Overview
Existing System:
• Type the text search the content who may not be able to read or write
people does not access it.

Drawbacks:
WAP(Cellular phones, Palm Pilots)access to the web:
 Small screens: For web phones, there's an incredibly small viewing area;
palmtops are barely better.

 Speed of access: All devices have slow access.

 Limited or fragmented availability: Wireless web access is sporadic in many
areas and entirely unavailable in other areas.

 Awkward input: Palm's Graffiti, touchtone pads, or even tiny QWERTY
keyboards are awkward for any amount of writing, even a short email.

 Price: Many technology limitations are being addressed by higher-end
devices and services. But the entry price for a good wireless web palmtop
with decent display, keyboard, and speed is easily $700 to $900, not
including monthly access.



 Lack of user habit: It takes some patience and overcoming the learning curve
to get the hang of it -- connecting, putting in an address, typing. Users just
aren't used to the idea and protocol yet.

Proposed System:
 Voice Browsers offer the promise of allowing everyone to access Web
based services from any phone, making it practical to access the Web
any time and anywhere, whether at home, on the move, or at work.
 Users will able to choose whether to respond by a key press or a
spoken command.
 Voice browsers allow people to access the Web using speech
synthesis, pre-recorded audio, and speech recognition.
Our plan:
 Accept the voice commands
 Output should be converted into speech

2.4. Communication Interface

• Voice based web browser will be connected to the World Wide Web.
• The HTTP protocol will be used to facilitate communication between the
client and server.

2.5 Product Function:

Voice based web browser-Easy to use - for people with no knowledge or fear of
computers. Voice interaction can escape the physical limitations on keypads and
displays as mobile devices become ever smaller. Many companies to offer services


over the phone via menus traversed using the phone's keypad. Voice Browsers are
the next generation of call centers, which will become Voice Web portals to the
company's services and related websites, whether accessed via the telephone network
or via the Internet. .

Some of the features of the product are as follow:
Accessing business information:

2.6. Constraints
• The information of all the users must be stored in a database that is accessible
by the Administrator.

• Voice based web browser system is connected to the computer and is running
all 24 hours a day.

• The users can access Online Book Sales with mobile SMS System from any
computer that has Internet browsing capabilities and an Internet connection.
