1. This document provides a final project report for developing a Virtual Personal Assistant using AI technology. It includes sections on analyzing the business case, requirements modeling, system design and implementation. 2. The requirements modeling section defines functional requirements for both administrators and common users, such as the ability to configure features, arrange the application interface, add personal interests, and get location-based suggestions. 3. The system design covers topics such as use case diagrams, sequence diagrams, class diagrams and state diagrams to model the voice recognition system and how users and administrators will interact with the application. Implementation details like supported file formats are also described.

3. INTRODUCTION

4. Introduction
AI is one of the newest fields in science and engineering.
Work started in earnest soon after World War II, and the
name itself was coined in 1956
AI currently encompasses a huge variety of subfields,
ranging from the general to the specific:
Playing chess
Proving mathematical theorems
Driving a car
Diagnosing diseases

5. Introduction

7. Speech recognition is used in
command based applications such as
data entry control systems, in mobile
devices such as in mobile phones and
to help people with hearing
disabilities.
According to Professor Todd
Austin (2007) Speech recognition
is the task of translating an acoustic
waveform representing human
speech into its corresponding
textual representation.

51. 7. Conclusion
1. To perform development methods, knowledge
workers and IT specialists meet to define and
review business requirements: joint application
development (JAD) and rapid application
development (RAD).
2. Meetings were arranged with IT department to
see what requirements are needed. At the end of
every meeting the meeting memorandums must
be clarified, checked to gather the requirements.
3. Feasibility analysis section of Preliminary
Investigation Report must be checked and all the
requirements should distribute among certain
requirement types.
