Appendix

1. Introduction1.1 MethodologyRational Unified Process Rational Unified Process (RUP) is an object-oriented and Web-enabled program development methodology. RUP is like an online mentor that provides guidelines, templates, and examples for all aspects and stages of program development. RUP is comprehensive software engineering tool that combine the procedural aspects of development with other components of development within a unifying framework. RUP establishes four phases of development, each of which is organized into a number of separate iterations that must satisfy defined criteria before the next phase is undertaken:

Inception phase : Developers define the scope of the project and its business case Elaboration phase : Developers analyze the project needs in greater detail and define its architectural foundation

Version 2.0

Construction phase : Developers create the application design and source code Transition phase : Developers deliver the system to users. RUP provides a prototype at the completion of each iteration.

1.2 PurposeThe essential purpose of Voice Based Web Browser is to enter from visual paradigm to voice paradigm -- including Admin and User. Voice browsers allow people to access the Web using speech synthesis, pre-recorded audio, and speech recognition. Voice interaction can escape the physical limitations on keypads and displays as mobile devices become ever smaller.

1.3 Scope

There are 2 basic users-Admin and User User must enter the voice command among the listed commands. Admin controls the entire access of the user, maintains History and Bookmarks.

1.4 Definitions, Acronyms, AbbreviationsAdmin Administrator, who is mainly responsible for making the browser ready to use, maintains History and Bookmarks thus providing access to the web browser for user.

Version 2.0WASCE WebSphere Application Server Community Edition[WASCE] is an Application Server that runs and supports J2EE and Web Service Applications. JSP Java Server Pages [JSP] is used to create dynamic web content. J2EE Java2 Enterprise Edition[J2EE] is a programming platform which is a part of java platform for developing and running distributed java. UML Unified Modeling Language is a standard language for writing software blueprints. The UML may be used to visualize, specify, construct and document. XML Extensible Markup Language is a text based format that let developers describe, deliver and exchange structured data between a range of applications to client for display and manipulation. HTTP Hyper Text Transfer Protocol is a service protocol. Eclipse Eclipse is a multi-language software development environment comprising a workspace and an extensible plug-in system. It is written mostly in Java. It can be used to develop applications in Java and, by means of various plug-ins, other programming languages.

1.5 Tools UsedRational Rose

Version 2.0Rational Rose is an object-oriented Unified Modeling Language (UML) software design tool intended for visual modeling and component construction of enterprise-level software applications. Rational Rose documents the diagram as it is being constructed and then generates code in the designer's choice of C++, Visual Basic, Java, Oracle8, Corba or Data Definition Language. Eclipse Eclipse can be used to develop applications in Java and, by means of various plug-ins, other programming languages. It can also be used to develop packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java. Eclipse began as an IBM Canada project. The Eclipse Platform uses plug-ins to provide all functionality within and on top of the runtime system, in contrast to some other applications, in which functionality is hard coded. The Eclipse Platform's runtime system is based on Equinox, an implementation of the OSGi core framework specification.

Version 2.0Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all gratis open standards.

Web Services A Web service is a method of communication between two electronic devices over the web. The W3C defines a "Web service" as "a software system designed to support interoperable machine-to-machine interaction over a network".

UML Unified Modeling Language (UML) is a standardized general-purpose modeling language in the field of object-oriented software engineering. The standard is managed, and was created, by the Object Management Group. UML includes a set of graphic notation techniques to create visual models of object-oriented software-intensive systems.

J2EE Java Platform, Enterprise Edition or Java EE is Oracle's enterprise java computing platform. The platform is primarily used for development of enterprise software, including network and web services, in the Java programming language. e-Forms An e-form (electronic form) is a computer program version of a paper form. Aside from eliminating the cost of printing, storing, and distributing pre-printed forms and the wastage of obsolete forms, e-forms can be filled out faster because the programming associated with them can automatically format, calculate, look up and validate information for the user. 1.8 Overview

Version 2.0Drawbacks

There is restriction on the number of commands. The user interface language is English only.

Proposed System

Interface provided to the user is a Web Browser. User- Interacts with the browser by providing voice commands. Admin Controls the activities of the user.

Our Plan

Designing an efficient Web Browser. Allowing the Browser to accept voice commands provided by the user. To provide desirable voice output to the user.
