Introduction:

Our semester project is an android app that will respond to user on calling a

particular name. The user will first set a name for its mobile and then if he loses

his phone or forgets after putting it somewhere in his house or office, he will callthat name and the phone will start ringing if he calls the correct name. The range

of voice recognition will be limited to one room.

Scope:

Scope of the application is limited , it will operate only 2 to 5 meter range in

length approximetaly equal to one normal room of 14 x 13 sq meter.

Objective:

This application will help people to find their mobile ,if mobile is available in

limited range.It will work in silent mode as well means sometimes our mobile is in

silent mode , when we call to our phone , we are unable to find our phone due tosilent mode, mobile was unable to ring the phone, so this application will ring

your phone even your mobile is in silent mode.Sometimes people disconnect your

sim from mobile when they found your mobile after that it is impossible to call on

mobile , so this app will run instead of your sim disconnected from phone.

Limitations:

1- The range of application is limited means it is applicable to room space only

even less than it.

2-

The phone must be switched on always to access this application or to findyour mobile.

3- Sometime due to noise of surrouding it will not interpret the same word as

user spoke.

4- It will not interpret the words other than English like (abbas , hussain,

mitho , pandey , saxena) etc



Functional Requirements:

1-Assign a name(keyword) to your application.

2-Alter name facility also available.

3-Save the name(keyword) into file using file handling.

4-Convert speech to text through speech recognition.

5-The spoken word will interpret same as user speaks.

6-Use the saved name(keyword) with name converted through speech

recognition for matching.

7-After successfull match mobile will ring.

8-Application would catter surrounding noise.

9-If mobile is in silent mode by default instead of this it must ring the phone.



Non-Functional Requirements:

1-Application will run 24/7 in background.

2-Surroundings sound will not impact speech recognition.

3-Application range will be enough means will operate in room space.

4-Response time should be less, as user will find his phone quickly.

5-If mobile is covered under some th , it will still catch the voice command and

will respond to it.

Architecture:

The architectural pattern we had used is pipe and filter,because stream of data is

passed through a series of processes.The processes are working concurrently in

the application.The processes are shown in component diagram below.
