ABSTRACT

Most of the times students pursuing their education come across some

technical terms whose explanation can’t be referred in dictionary but often use

Wikipedia to get the relevant explanation. Wikipedia is a Web-based, free-content

encyclopedia. It is one of the most popular reference sites on the Internet. There are

many cases when it is not possible to read the Wikipedia web page. So the aim of the

project is to bring the power of Wikipedia on your mobile phone. The end output will

be like this. If I send “Flash memory” from my mobile as SMS to a particular number

assigned for this service, I will get a call from the service and I will be able to hear the

Wikipedia entry for “Flash memory” as voice.

1. INTRODUCTION

1.1 OBJECTIVE OF THE PROJECT

Most of the times students pursuing their education come across some technical terms

whose explanation can’t be referred in dictionary but often use Wikipedia to get the relevant

explanation. Wikipedia is a Web-based, free-content encyclopedia. It is one of the most popular

reference sites on the Internet. There are many cases when it is not possible to read the

Wikipedia web page. So the aim of the project is to bring the power of Wikipedia on your mobile

phone. The end output will be like this. If I send “Flash memory” from my mobile as SMS to a

particular number assigned for this service, I will get a call from the service and I will be able to

hear the Wikipedia entry for “Flash memory” as voice.

1.2. PROJECT CATEGORY

VOICE WIKI ON MOBILE PHONR is desktop based application

software. The software is installed on a computer which will act as the server. This computer will

accept the request from the user, process it and sends the output back to the user.

Application software, also known as an application or an "app",

is computer software designed to help the user to perform singular or multiple related specific

tasks. It helps to solve problems in the real world. A software application, or program, is a set of

logical conditions grouped together to perform some function. Typically a Microsoft Windows

application will be run within a "window" although that is not a requirement. A "window" in the

context of software is an area of the screen set aside to run a single program and may or may not

have options for controlling the position and size of the program area.

Desktop-based applications have facilitated enterprises to perform

dynamically with easy access to information. These applications are more powerful, persistent

and offer better functionality. That’s why there has been an increase in the demand for

conversion of most internal enterprise applications to flex applications that are web based.

2.EXISTING AND PROPOSED SYSTEM

Existing System:

Wikipedia is mainly accessed through internet enabled computers using web browsers. But it is

not possible to access Wikipedia as such all the time, since we require an internet enabled

computer. We can also get access to Wikipedia on our cell phone using Wikipedia mobile web.

But it also requires an Internet enabled mobile phone with an internet connectivity provided by

the service provider.

Limitations of existing system:

User need computer

User need internet

User need internet enabled phone

Searching not possible at any time

Proposed System:

Proposed system enables users to access Wikipedia using mobile phone by sending a sms (short

message service). It is easy to use and can be accessed from anywhere at any time and it is less

expensive compared to other existing systems. The user can use any kind of mobile phone and

doesn’t require an Internet connection or any other additional functionality.

Features of proposed system:

User doesn’t need a computer

User can use any mobile phone

User doesn’t need an internet connection

Searching is possible at any time

3.TECHNOLOGY USED

MS Visual Studio 2005

Microsoft Visual Studio is an integrated development environment (IDE) from Microsoft. It

can be used to develop console and graphical user interface applications along with Windows

Forms applications, web sites, web applications, and web services in both native code

together with managed code for all platforms supported by Microsoft Windows, Windows

Mobile, Windows CE, .NET Framework, .NET Compact Framework and Microsoft

Silverlight.

Visual Studio includes a code editor supporting IntelliSense as well as code refactoring. The

integrated debugger works both as a source-level debugger and a machine- level debugger.

Other built- in tools include a forms designer for building GUI applications, web designer,

class designer, and database schema designer. It accepts plug- ins that enhance the

functionality at almost every level—including adding support for source-control systems

(like Subversion and Visual SourceSafe) and adding new toolsets like editors and visual

designers for domain-specific languages or toolsets for other aspects of the software

development lifecycle (like the Team Foundation Server client: Team Explorer).

Visual Studio 2005, codenamed Whidbey (a reference to Whidbey Island in Puget Sound),

was released online in October 2005 and to retail stores a few weeks later. Microsoft

removed the ".NET" moniker from Visual Studio 2005 (as well as every other product with

.NET in its name), but it still primarily targets the .NET Framework, which was upgraded to

version 2.0. It is the last version available for Windows 2000 and also the last version to be

able to target Windows 98, Windows Me and Windows NT 4.0 for C++ applications.Visual

Studio 2005 was upgraded to support all the new features introduced in .NET Framework

2.0, including generics and ASP.NET 2.0.

C#.NET

C# is a simple,modern,general-purpose,object-oriented programming language.

It was developed by Microsoft within the .NET initiative and later approved as a standard

by Ecma (ECMA-334) and ISO (ISO/IEC 23270).

The language is intended for use in developing software components suitable for

deployment in distributed environments.

Microsoft Visual C# is Microsoft's implementation of the C# specification, included in

the Microsoft Visual Studio suite of products.

It is based on the ECMA/ISO specification of the C# language, which Microsoft also

created.

MS SQL

Microsoft SQL Server is a relational model database server produced by Microsoft

Microsoft SQL Server is an application used to create computer databases for the

Microsoft Windows family of server operating systems.

Microsoft SQL Server is a relational database management system.

It supports Structured Query Language (SQL), which is the most common database

language in use today.

While it is most popular for use with small to medium sized databases, it has been

catching on for use with large enterprise databases in recent years.

4.SYSTEM DESIGN

4.1 MODULES

There are 4 modules in “VOICE WIKI ON MOBILE PHONE”; they are listed below, following

a brief discussion.

1) Retrieving SMS

2) Wikipedia Search

3) Convert text to Voice

4) Revert Call

Retrieving SMS

This module allows you to send and receive SMS messages using AT commands.

AT commands are instructions used to control a modem. GSM/GPRS modems and mobile

phones that we use along with the system support an AT command set that is specific to the

GSM technology, which includes SMS-related commands to send and receive messages.

Wikipedia Search

This module allows you to extract the keyword searched by the user, and later a Wikipedia

search of the user keyword is performed and the resulting information is extracted. The extracted

data from the net is in text format.

Convert text to Voice

This module helps to convert the searched content to voice format. Here the text file of the

retrieved data from Wikipedia is converted to voice format. This module uses the speech

recognition system.

Revert Call

This module revert a call to the sender and give the information in the voice format. This

can be done using a audio streaming server.

The user sends a sms containing the keyword to the system. The

systems then search the keyword on Wikipedia and retrieve the corresponding data. It then

converts the text data into an audio format and gives the user the output in the form of a call.
