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.•

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:
• The corporate "front desk" which asks callers who or what they want
