3. ACKNOWLEDGEMENTS
My project is the result of the encouragement of many people who helped to
shape it and provided feedback, direction and valuable support. It is with hearty
gratitude that I acknowledge their contributions to my project.
I would like to thank my internal guide Ms.Shameena Pk for the constant
help and support extended towards me during the course of the project. I am also
grateful to our Head of the Dept, Mr.Gireesan T K, Department of Information
Technology, for permitting me to take up this project and her encouragement. I thank
my Principal, Dr.Shoukath Ali Karuvatt who has always been a great source of
inspiration.
Last, but not the least, I would like to thank my peers and friends who
provided me with valuable suggestions to improve my project.

4. 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.

1.2. 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.
Conve rt 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.

5. REQUIREMENT SPECIF ICATION
Software requirement specification (SRS) forms the basis of software
development. The requirements document (SRS) is the official statement of what is required of
the system developers. It should include a detailed specification of the system requirements. It
helps to check if the software has met the requirements. Hence a high quality SRS is a
prerequisite to high quality software. This chapter gives an overview on the following
information:
