Abstract - Home Automation has gained light over the past
few years. It is viewed as a necessity than a luxury in many
aspects. With the help of home automation, it has eased the
daily lifestyle of the physically disabled and elderly age
group of our society. Our proposed system reaches out to
help these neglected groups of our society by giving them a
sense of independence in their daily chores for different
functionalities and purposes. We aim in developing an
economical and efficient home automation system that will
work in proximity to home appliances. The voice command
recognition is achieved using dedicated hardware
components and an Arduino board to read inputs. Thus our
system can be used for the conversion of existing homes into
smart automated homes at economical, robust and flexible
approaches.
Key Words: home automation, speech recognition,
voice commands, internet of things, economical home
automation
1. INTRODUCTION
Smart Home Automation system is becoming popular
these days and voice-controlled smart home environment
is getting special attention. voice recognition technologies
with fully embedded systems are already available[1].
Various sensors and smart devices are already available
on the market, as well as HA systems, which let users
connect, monitor and control their devices. Mobiles and
Web applications are used to control various Home
Automation Systems(HAS). Meanwhile, we are witnessing
the growth of popularity of voice command interfaces
(VCI). Recently, a number of devices have appeared on the
market, which are powered by the online voice
recognition engines, and can serve as the VCI for HA
systems[2]. An essential part of SHAS is to enable the
various electrical devices and electronic gadgets in it to
interact and communicate with each other. In SHAS,
simple remote-controlled systems to complex
computer/micro-controlled home automation
technologies and different wired/wireless technologies
may be used for this.Few widely used wireless
technologies with globally accepted standards are: GSM,
Wi-Fi, NFC and Bluetooth. These can be used to
communicate with the smart electrical devices via smart
mobile devices such as smartphone or tablet [3]. In this
paper we use voice recognition to control smart home
appliances. Apart from the traditional methods like
keyboard or switches for controlling the device, voice
control is one of the easiest methods to give input
commands and also, since it can be adapted and
customized to a particular speaker’s voice therefore voice
recognition is a more personalized form of control. As
Hindi voice commands are considered only that will be
useful for people in India. Also this system is very much
cost-effective than any other Voice based Home
Automation System available in today’s market.
1.1 Advantages of System
Home Automation allows you to gain the perks of high-end
technology and its functionalities which wasn’t possible in
the past. Our proposed system points to many advantages:
1. Our proposed system provides flexibility to the
user integrated with our module. He/She can
monitor or control all the devices from one place.
2. Our proposed system proves to be economical as
compared to the existing systems. Thus this
system is devised in such a way that it is easily
affordable by the common man.
3. Our system reaches out to the often neglected
group of society which are the elderly people and
the physically disabled. Thus making their life
easier. Our system aims in providing them a sense
of independence in daily lives.
4. Only 10% of India’s population can fluently
understand and reciprocate in English; which
leaves out the other 90% population which
conveys only using their regional native language.
2. LITERATURE SURVEY
Yash Mittal el al. [3] proposed a multi-functional `Smart
Home Automation System' (SHAS), that can be adapted to
a user's voice and recognize the voice-commands,
independent of the speaker's personal characteristics such
as accent. An Arduino microcontroller board is used for
processing and control which makes this system cost-
effective. Thus for converting existing homes into a smart
home this prototype i.e Smart Home Automation
System(SHAS) can be used.
Chen-Yen Peng et al.[4] designed and built a tailor-made
function for users without their attempt. Commands are
taken from Google Home’s voice recognition and
Bluetooth signals are transferred to Raspberry Pi to
control the connected devices. The proposed paper mainly
focuses on researching combining characteristics of
Google Home with Google Assistant Personal Voice

Assistant using machine learning and thereby customizing
this to meet the new needs of users.
Hem Kamdar et al. [5] implemented various ways in which
people can automate their homes. The proposed system is
built by using the Arduino microcontroller and voice
recognition module. based on the voice input Arduino
gives commands to various connected devices. this system
provides a cost-effective and a robust home automation
system.
Norhafizah bt Aripin et al. [6] presented a review on an
Android-based voice-controlled home automation system.
In this paper voice inputs are captured by android and
sent to Arduino Uno. Bluetooth module in Arduino Uno
receives the signals and processed the input signals to
control electrical appliances.
Eleonora Nan et al. [7] implemented and designed one
solution to enable voice control within the existing home
automation system. An online voice recognition engine is
combined with the existing home automation system.
Response time and accuracy are measured and it is
confirmed that practically this system can perform well.
3. SYSTEM ANALYSIS
3.1 Problem Statement
Nowadays, Home automation is only available in a few
defined languages (English). Our proposed system helps
us to make home automation available in more native and
convenient languages for the users.
3.2 Proposed System Feature
1. Python provides a large standard library which
includes areas like internet protocols, string
operations, web services tools and operating
system interfaces. Many high use programming
tasks have already been scripted into the standard
library which reduces the length of code to be
written significantly.
2. Python has clean object-oriented design, provides
enhanced process control capabilities, and
possesses strong integration and text processing
capabilities and its own unit testing framework,
all of which contribute to the increase in its speed
and productivity. Python is considered a viable
option for building complex multi-protocol
network applications.
3. The Arduino software runs on Windows,
Macintosh OSX, and Linux operating systems.
Most microcontroller systems are limited to
Windows.
4. Arduino boards are relatively inexpensive
compared to other microcontroller platforms.
4. SYSTEM DESIGN AND IMPLEMENTATION
Figure 1: Proposed Model Of Home Automation System.
The proposed model of the home automation system is as
shown in the above figure 1. The model consists of a
microphone to accept commands from the user. It also
consists of an Arduino Uno which is an interface between
the hardware components like Home lights, fans, Air-
conditioner, etc. The model also consists of Voice assistant
as a front-end software which is used to understand the
command given by the user. Our Python-based Voice
assistant uses google text-to-speech API to understand all
the words spoken by the user, and based on certain
conditions that satisfy being a command the voice
assistant sends responses to the Arduino Uno.

in the background listening for available voice commands;
once the user gives a command, based on the conditions
provided to the voice assistant, the voice assistant gives
the necessary output. This output is sent to the Arduino
Uno board which is connected to the system. Based on the
input received the Arduino Uno then performs the desired
task.
5. CONCLUSION
Our proposed system Home Automation in Hindi language
Voice commands can be implemented using dedicated
hardware i.e. Arduino Uno and using voice recognition
module thus makes the system more cost-efficient and
robust. The system can work on various connected devices
like light, fan, AC, etc. This system provides a basic system
of Home Automation which can be easily implemented and
used effectively. Also this system allows users to make
decisions and to regulate the home appliances with the
help of voice assistants, thus making one’s life comfortable
and at the same time remotely accessible via voice
commands.
6. FUTURE SCOPE
Using this system as a framework, the system can be
expanded to home security. Home security is important
these days so it can be combined with this system to give
more advanced features. Also in the home automation
system another feature like modulating according to the
moods of a user. More advancement can be done by
enabling a system to work on various languages of rural
areas. Further modifications are possible like operating on
various tones or accents from different regions that mean
it should be able to perform operations on various voice
tones and accents.
