Hands-on change voice control makes smart home more intelligent [Full text]

Technology Trends With the advent of the artificial intelligence era, intelligent voice control has gradually become an industry need in smart homes. According to the data from the White Paper on the development of China's voice industry in 2014, the scale of the global intelligent voice industry has exceeded US$4.75 billion in 2014, which is nearly double the growth rate of US$2.44 billion in 2012.

However, due to the complex principles of intelligent voice technology, long development cycle, large investment, and high barriers to entry, globally, there has been an oligopolistic competition, with only a few companies such as Nuance, IBM, Microsoft, and Google having strong competition. force.

For people, the voice function is not a new technology, but the control of devices such as door locks, light bulbs, and household appliances will become “a word thing.” It’s still cool to think of it, and google is doing a good job in this area. Not long ago, Google’s smart home device announced the integration of Google’s voice service system to provide users with a mobile device to operate Nest’s voice service. When the user speaks the demand, the command is sent through the Google Card that pops up in the application, letting you know that your Nest is implementing functions such as adjusting temperature.

However, Google's voice control may not be the same as we imagine. First of all, this kind of function is still limited. Although the ability of the google speech system to recognize common languages ​​has been fully extended to Nest, we can say or say that the Nest thermostat can understand quite a few things. It is not really possible to chat with it for days. It's not as smart as it looks like. What's more important is that the way this function is implemented is through mobile devices. It does not work directly against the Nest thermostat. In other words, this kind of voice control does not seem to be separated from smart phones or other mobile devices.

In fact, Nest said in late June this year that the Nest device will connect some google applications, allowing Nest users to post voice commands to the Google mobile app and then complete the indoor temperature setting. Of course, not wanting to do this kind of thing is just google family, there is google's old rival apple.

At the beginning of June 20 days before Nest said that the Nest device will connect some of Google’s applications, Apple made a similar move. Apple launched Homekit, a smart home platform at WWDC (Apple Global Developers Conference), and hopes to enable users to use Apple mobile phones to implement intelligent door locks, thermostats, smart switches, smart cameras, smart sockets, etc. through cooperation with third-party hardware manufacturers. Equipment control. Crucially, Homekit also plans to integrate Apple’s smart voice assistant, siri, to enable users’ voice control of home devices and make smart homes simpler.

Although Apple's voice control smart home is more like a concept, it has no practical value at present, but its leading role is still very large. After Apple, not only Google has the idea of ​​introducing smart home voice control, but Microsoft also plans to launch smart home based on Cortana voice control. Earlier, foreign media reported that "the network engineering team at Microsoft's Asian Department is working hard to make China's WP8.1 Cortana more useful, adding to its family intelligent support." However, similar to the other two, Microsoft's voice control smart home is not mature.

It is undeniable that smart home voice control is an improvement. At least we have more choices. It is even easier to control some devices without touching the phone screen with your hands. However, this is really the voice control that smart home needs? the answer is negative.

Prior to voice control, many people viewed the mobile phone APP control smart home as a "fat tasteless". In addition to remote monitoring, the mobile phone is more like a home device remote control. Although the control is strong but not intelligent, sometimes it will not only bring convenience to the smart home, but will be even more troublesome. The original turn on the lights, we must go to click on the switch, and now although we do not need to move, but we need to take out the phone, open the software, find out the equipment, click control and a series of operations, and did not think so simple. In addition, for the elderly, the physical remote control is much easier to use than the mobile phone controls.

Voice control has been changed from "hands-on" to "moving", but the constant is that it still needs a mobile phone or other mobile device. It is not just a mouth. It may be too far from the "Iron Man" scenario. In "Iron Man," male actor Tony Stark's AI steward Jarvis, who has close to real human wisdom, is obviously much more advanced. Not only can he provide the corresponding program according to the owner's needs, but he can also "talk" and "teach" the owner. ". Of course, "Iron Man" is a science fiction movie after all. Real life is difficult to realize in a short while, but voice control can be more convenient or can be expected.

Currently speaking, voice control is basically controlled indirectly and needs to be completed by means of a mobile phone rather than directly by the device. However, in reality, we need to directly issue commands to the device to control the device. For example, if you want to turn on the lights and turn off the lights, say "Turn on the lights" or "turn off the lights." Lights can be turned on or off on their own, instead of requiring us to send commands to the phone, through the phone's voice. Function or voice assistant to realize voice control of smart home.

Compared with hand-drawing on mobile phones, voice control is undoubtedly closer to real people and more natural, and it also makes smart homes more intelligent, but “the voice control must not pass the mobile phone, it is a problem”. This may be Google, Apple and other Internet companies and we need to solve the voice control exploration process.
