8. Scope of the Project
The application is designed to teach beginners. At minimum
we try to include the following:
Most frequently used vocabularies including pronunciation
Numbers and alphabets including pronunciation of native
speakers and equivalent English spelling
Most Frequently used phrases used in communication
And some sentence construction.
Some Afan Oromo language grammatical rules.
All lessons separated in to module.
Tests at the end of every lesson to enhance user knowledge.

9. Continue….
This application cannot teach the whole Afan Oromo
language and all its grammatical rule.
 Vocabularies used not pass more than 300 words.
Sentence construction used as example not to teach
deeply the language grammar.
The application only for English language speakers.
Also the major difficulty of this application is platform
dependency.

10. Significance of the project
After successful implementation of the application user
 learn Afan Oromo any time anywhere, saving money
spend during class tutor, using a new afan Oromo
mobile learning application.
 As Afan Oromo is one of the languages most spoken
in the Africa, there is few works for development of the
language that done in software’s area. Thus this work
may become one from few works that contribute for
the development of the language

13. Systems Analysis and Design
approach
Development methodology (OOSD). This has two
phases.
Object Oriented Analysis (OOA)
 During this phase the team used to Model the
functions of the system (use case modeling),
Object Oriented Design (OOD)
 During this phase the team used to refine the use case
model to reflect the implementation environment,
Model object interactions and behaviors that support
the use case scenario, and finally update object model.

Description of the Existing System & the Proposed
System
Introduction of Existing System
The first step of preliminary study in the system analysis
process involves the identification of needs are:-
Manual Based
students go to class and learn the lesson from their
teacher by sitting in the class room
Afan Oromo Learning Android Application(Bakkalcha Barii) 20

21. Introduction of Existing System
Web page applications
In the internet we can find many language learning
tools and WebPages. here as example two popular
WebPages designed for language learning.
“i languages.org” is web site designed to teach
languages on internet. The site contains about 92
languages spoken throughout world. Most of the
topics included are vocabulary, grammar and
phrases.
Afan Oromo Learning Android Application(Bakkalcha Barii) 21

22. Continue….
“digital dialects”. A web Site designed to teach about 70
languages spoken in the world through games. It has
interactive and visualized picture and movie. Each
game has its own lesson that contain tutorial about
specific game and some of which supported by audio
and movies. The games categorized in to phrases,
numbers, spelling and alphabet. Its suitable game to
understand basic vocabulary words specially for
beginners. But this game teaches few words and always
need connection.

23. Continue….
Window software’s
There are many windows software application for language
learning. We can find many language learning tools freely
and commercially. Here we list as example two windows
software designed for language learning. One designed for in
Afan Oromo and other for English learning purpose. Among
that “Oromiffa the EZ way” is commercial windows computer
software designed to teach Afan Oromo easy way for
foreigners. It can be used by absolute beginners or
intermediate level users. The programs teach
pronunciations, words, phrases, contain games and quizzes.
But it is platform dependent (only works on windows) and
price cost is expensive.
