With more and more devices supporting the control mode of voice interaction, the voice interaction entrance will change from single device control to multi-device distributed control. The development of the Internet of Things technology has supported the further expansion of the range of voice interaction, making the interaction entrance of home devices more distributed and the interaction experience more collaborative. At the same time, the full scene interconnection experience of home appliances will be further enhanced, the digital services around the home scene will be more abundant, and the smart home will be closer and closer to the life of ordinary people. Bluetooth speakers that can switch the curtain by voice control, smart light bulbs that will automatically reduce the brightness when the screen is dropped, smart gas stoves that immediately send alarm prompts to users' mobile phones when they find a dangerous situation... With more and more household appliances connected to the Internet and the Internet of Things, these scenes that seem to only appear in science fiction movies are gradually becoming reality. However, a real and serious problem lies before manufacturers and users. Because different smart home brands have different ecosystems, as well as different data security, port standards and other settings, "exclusion" has become a common phenomenon, which makes "interconnection difficult" become a major obstacle in the digital transformation of traditional household appliances. Recently, Apple entered the smart home market in China with a low profile. Nearly 30 smart home products have been launched on its official website. The product types include cameras, light bulbs, door locks, switches, routers, sockets, and so on. According to relevant reports, Apple's connection agreement, the Matter agreement, is different from the proprietary agreement that would form a brand barrier in the past. This agreement can realize the connection of cross-brand smart home devices. This makes one wonder whether the good wish of interconnection of household appliances is really to be realized? With the accelerated development of the new generation of information technology such as artificial intelligence and cloud computing, as well as the gradual growth of young consumers as the main force of consumption, digital home appliances of different brands are becoming the main trend of the development of the home industry in recent years, and increasingly becoming the new growth point of the home market. The data shows that from 2016 to 2021, the scale of China's smart home market increased from 260 billion yuan to 580 billion yuan, with an average annual growth rate of nearly 20%. In addition, many leading enterprises in China have actively laid out the smart home ecosystem, and relevant applications have been implemented in various life scenarios such as home security, smart kitchen, smart sleep, etc. "The speed of Internet transformation of traditional household appliances is related to its user value and user scenario." Sun Li, the chief technical officer of TCL Industrial Holding Co., Ltd., said in an interview with the reporter of Science and Technology Daily, for example, in midsummer, turning on the air conditioner before going home can meet the needs of users, so the transformation of air conditioner has developed rapidly. "In addition to the user's scenario needs, it also depends on the cost of technology." Sun Li said that with the popularization of Wi-Fi chips, Bluetooth chips, cloud computing, mobile application apps and other products, the cost of home appliance interconnection is becoming lower and lower, and consumers' willingness to pay is also increasing, prompting more and more manufacturers to invest more costs to promote home appliances
