SRS Voice Controlled based Smart Home for Handicapped Peoples

Home automation is the future and an important part of a house. Home automation is highly reliable in the system for controlling house electrical appliances and other home-based ornaments like temperature, humidity, etc. As technologies improve the home automation system is becoming smarter and can regulate certain tasks automatically and autonomously. The home automation systems are cost-effective and reduce the consumption of energy in the household and cut the cost of electricity bills. The voice-controlled smart home automation system helps to control electrical appliances by
using voice commands. The system uses a Bluetooth module for data transmission for controlling the functioning of electrical loads. The Bluetooth can receive an input signal from any device which has Bluetooth compatibility such as a smartphone. Smart home automation is most beneficial for handicapped or aged people. The system solves the problem of switching on/off electrical appliances because when the user just has to give a voice command to control the appliance or electrical loads. The system is designed in such a way users can control all appliances at once or can control each separately. The system works by interfacing the on/off switches of electrical appliances or loads by using a mechanical relay or solid-state replay, after connecting relays in the system the electrical switch works as a two-way switch. The voice command is sent by using software designed for controlling the system, a built-in microphone, and a voice recognition system implemented in the device. A micro-controller-based design is implemented in the system, the microcontroller receives an input signal from the user
device and sent a signal to the respective relay for turning on/off electrical appliances connected with a system such as bulbs, and fans, air conditioner units, etc. Last, one of the major functions of the system is to call for help. Your system must be capable for generate a signal for help based on voice input.

Use Case Diagram of Diagnosis of Voice Controlled based Smart Home for Handicapped Peoples

a use case diagram can summarize the details of your system’s users   and their interactions with the system. Scenarios in which your system or application interacts with organizations, people, or external systems. Goals that your system or application helps those entities achieve

Usage Scenarios Diagnosis of Voice Controlled based Smart Home for Handicapped Peoples:

A brief user story explaining who is using the system and what they are trying to accomplish. A Scenario is made up of a number of simple, discrete steps that are designated as being performed by either the System or a  User.

ADOPTED METHODOLOGY for Voice Controlled based Smart Home for Handicapped Peoples:

The adopted methodology for this project is vu process model. Vu process model is a combination of water-fall model and spiral model. This combination has many advantages. This model has high risk analysis so avoidance of risk would be achieved. This model is easy to understand and use. Now first we will discuss the Water-fall model.
