The growing need for better living circumstances has accelerated the development of smart houses. Smart houses link smart gadgets in the household, then register every device to the cloud, and enable remote control via mobile terminals.

From its inception until today, the smart home has also gone through three stages in terms of technology. To begin, the gadget was linked to a smart house system through home network in order to complete its control. The wired access approach made smart house installation and maintenance difficult.

People in smart homes may interact and operate gadgets in natural language using speech recognition technology, which substantially enhances the experience and fits people’s consumer requirements. In this regard, employing speech recognition in smart houses is generalized. 

The domestic environment is the foundation of smart homes, which use wireless network technology, automatic control, and speech recognition technology to connect home appliances and utilities to create an effective home management system that improves the ease and comfort of home life.

A smart home is a wireless network that links numerous household facilities and enables several services such as home appliance management, lighting control, and interior and exterior remote control. Smart houses not only include the functionality of traditional homes, but they also have automated and intelligent features that may save money and energy.

With the dawn of information technology, computers have become increasingly important everyday tools for individuals, and speech is the most direct means for humans to convey their thoughts, views, and feelings.

Let it have the same capacity to comprehend words as humans as a human speech interaction object, which will create a tremendous difference in people’s livelihood and working ways, and a speech human-computer interactive system based on technology that recognizes voices will arise as the times dictate.

The goal of smart homes is to give consumers a peaceful, secure, and convenient home living experience while overcoming the inadequacies of existing electrical control methods. Traditional home appliances control includes drawbacks such as hard maintenance, limited scalability, and expensive price.

At the same time, issues such as deteriorating wiring endanger the safeguarding of family property. The push switch is often used to control an electric appliance in the traditional manner. In general, the considerable proximity between the electrical appliance and the controlling switch necessitates elaborate cabling that is difficult to regulate and has limited scalability.

In this design, ZigBee wireless communication was being used here between remote control as well as the receiving end, as opposed to the typical electrical control approach. The system is extensively integrated, as well as the remote control may be operated by running related programs in “one-to-many” & “many-to-one” modes.

Home control and automation systems, as fundamental components of smart houses, have played an important part in the evolution of our living surroundings. They have a wide range of uses at home, including security and surveillance, medical, power, and entertainment. People continue to strive to delegate various tasks as human living conditions rise towards smart house systems.

In a smart home context, such a system is capable of anticipating what the user plans to do.

However, there are several difficulties that require more examination and resolution, such as:

• Many studies focus on a single application rather than combining many apps in a single environment.
• There’s no study that attempts to demonstrate the true effect or even examines the implementation of expected actions generated via the home intelligent gateway.
• There’s an incompatibility issue owing to the use of different types of home apps with distinct message context protocols.

The real-world impact of projected actions once they are implemented by an internal control in a simulated home setting, as well as the theory behind the prediction process, are demonstrated by studying Using an intelligent gateway, an analysis of a sequence of user contact events with diverse and dispersed components in the environment is performed. Certain analytical techniques can be used to predict the next stakeholder action.

The suggested method has three primary novelties:

I)Creating a learning approach incorporated in an internal control to construct a model of user behavior and interactions in order to balance the demands of various users in a smart home setting.

II)Presents and highlights the interaction paradigm for a local area network (LAN) built on a degree of centrality criterion, which assists enterprise organizations such as Google, Amazon, Microsoft, and Xively in understanding its most significant services of their clients.

III)The suggested system demonstrates a high-level notion of how we may create an intelligent system self-adaptive technology in the home setting capable of providing local services to stakeholders while also supporting the usage of the IoT paradigm concurrently.

Smart homes have become a particularly intriguing subject for academics over the last few decades. Many of the experiments focused on how to monitor and regulate various zones in a single residence. The categorization is divided into four areas of interest: security, energy efficiency, health care, and entertainment. The Functional Organization of the Smart Home System highlights four major types of applications that have been enabled by the creation of a smart environment in our homes. It demonstrates how sensors, actuators, and devices in the planned system may be categorized based on its functioning. 

For example, we can observe that the security box has numerous security nodes with comparable capabilities, such as entrance door sensors, motion sensors, smoke sensors, and CCTV. The healthcare box contains nodes related with personal health, as well as elderly or disabled persons. All of these boxes are linked to a gateway.

We frequently come into contact with or purchase smart home items in our everyday lives. Lights, air con, surveillance, and kitchen appliances are just a few examples of smart home items. The smart LCD module, which is mostly utilized in smart homes, has an RS232 interface, a wide viewing angle, and a capacitive touch screen design. All smart home elements are provided through an LCD module through the control, and all the functions get realized by touch operation.  These include indoor temperature, , lighting conditions, smart door locks and humidity.

The LCD display provides real-time monitoring, and we simply have to touch the respective control buttons just on screen to set and modify the intensity of light as well as the interior temperature. It also includes features like on/off timing. Smart houses LCD not only eases the burden and makes life easier, but it also creates a more enjoyable and comfortable ideal home environment.

Conclusion

Smart homes, being a result of the modern era, have a distinct mission. The ultimate goal of smart house development is to better satisfy people’s life necessities. To advance in this approach, research on integrated voice control system for smart homes is being conducted.

In the framework of the study on smart house, this article combines voice commands, ZigBee technology, with the most common system software and, after evaluating the cost, provides a set of practical voice control system alternatives. The intelligent terminal detects the speech signal as an unique voice command and through process of pretreatment, extraction of features, pattern classification, post-processing, etc., and delivers it to the main command center for analysis.

The radio wave communication transmits the voice recognition to the relevant control node, and lastly, the node detects the control command via the voice control and delivers the command directly to control the home appliance while also replying to and providing feedback to the primary control center.

This article incorporates functionalities such as audio collecting, family member confirmation, voice command recognition, possible environmental information gathering, and control command transmission, and performs experimental testing on diverse functional modules, with normal test results.

The results of the tests reveal that family members may appropriately utilize the system and accomplish the aim of effective control of house facilities by using voice commands in conjunction with family members.

The system’s present star-shaped network architecture is simple and straightforward to use, but when there is a big quantity of sensors, the system requires a huge number of information gathering nodes, which dramatically increases the system cost.

At the moment, the galaxy structure is more expensive than that of the trees and mesh structures. As a result, depending on the unique circumstance, the system has to be improved at this stage.

Furthermore, because the system must interact with the cloud regularly while operating, this procedure is time-consuming, and wireless technology also takes time, making the whole system’s reaction a little slow. The benefit will be magnified if the overall system’s reaction time can be improved.
