Smart home not only has the functions of traditional home but also has the characteristics of automatic and intelligent and can even save energy and money. Smart home connects various household facilities into a wireless network and provides multiple functions such as home appliance control, lighting control, and indoor and outdoor remote control. Smart home is based on the residential environment, using wireless network technology, automated control, and voice recognition technology to integrate home appliances and facilities to establish an efficient home management system to enhance the convenience and comfort of home life. From this perspective, using voice recognition in smart homes has a very broad prospect.
Using voice recognition technology in smart homes, people can communicate and control in natural language with devices, which greatly improves experience and meets people’s consumer needs. In recent years, related technologies have made huge breakthroughs, which have rapidly improved the accuracy of speech recognition. Compared with the former, this method has become more mature and more convenient to use, but it is still in the stage of “weak intelligence” and cannot meet the needs of intelligence and humanization. The wired access method made the installation and maintenance of the smart home become cumbersome. At the beginning, the device was connected to a smart home system through the home bus technology to complete the control. From a technical point of view, from the development to the present, the smart home has gone through three stages. Smart homes realize the interconnection of smart devices in the home, register each device on the cloud, and implement remote control through mobile terminals.
People’s increasing demand for living conditions has catalyzed the emergence of smart homes. The test results show that the system can control home facilities through voice commands combined with real-time environmental information while confirming family members. The system is tested and analyzed under experimental conditions.
#Wireless home control serial
The upper computer sends the control command to the lower computer through the serial port to control the corresponding home equipment. After the system is started, the family members are first confirmed by voice, and then, the voice command recognition result and real-time environmental information jointly decide to form a control command. The upper computer transplants the audio library and the algorithm studied in this paper to realize the audio collection and storage, the confirmation of family members, and the recognition of voice commands the lower computer is used for real-time collection of environmental information and wireless control of home facilities. In the key control scheme, users can control home appliances through keys on the smart terminal. After the recognition is successful, the user can control the home appliances through the command. In the voice control solution, the user first reads the control commands set in the voice library on the smart terminal, and then, the system automatically recognizes the commands read by the user. In order to make the system more humane, two sets of control schemes, voice control and button control, are designed according to the system’s functional requirements.
#Wireless home control software
According to this scheme, the hardware and software of the system are designed, and the wireless communication method combining Wi-Fi and RF (radio frequency) of the system is also determined. This paper designs the overall scheme of a smart home control system based on voice recognition technology. The system adopts ZigBee wireless communication to form a comprehensive management system for household electrical appliances, electronic and electrical equipment, etc., for household electrical control, intelligent security, and environmental monitoring. Under the premise of fully studying the research status and development trend of smart home systems, this paper combines embedded technology, ZigBee wireless communication technology, voice recognition technology, GSM communication technology, etc., and proposes a ZigBee-based smart voice home appliance control system. The continuous development of embedded technology, short-range wireless communication technology, and microcontroller technology provides a new development direction for the research and development of smart home systems. With the rapid development of economy, science, and technology, people have higher and higher requirements for the quality of home life, and smart home systems are required to have higher convenience and comfort.
