Perhaps you like the idea of controlling your home appliances with your voice, but aren’t super keen on a data center processing recordings of you. Fair enough. The trade-off for most smart home conveniences is relinquishing at least some of your privacy. Today at CES, I saw a line of voice-controlled home appliances from Emerson Smart that adjust power and setting via voice commands. But commands are recognized on the devices themselves, not carried through Wi-Fi and processed elsewhere. The huge array of smart plugs, fans, heaters and even air fryers require no app for setup and don’t need access to Wi-Fi. Instead, I said, “hey Emerson, lights on” or “hey fan, turn on low” and the devices in the demo space acted accordingly. A few of the devices combine the mic with a speaker and can respond when a command is received. A bit of built-in programing on the air fryers allow them to understand commands for 100 cooking presets, so saying things like, “reheat this pizza” or “cook these frozen french fries” will set the correct mode, time and temp. Of course you can also just say, “cook at 350 degrees for 10 minutes” and it’ll comply. Most of the commands for the other items are pretty simple but allow you to do things like set a timer, turn on oscillation and set intensity speeds. Some of the devices allow for a small amount of programmability. Pressing and holding the button on the smart plug, for example, changes the wake word to “plug two,” doing it again swaps it to “plug three,” and so on. That way, if you have more than one plug in a room, you can operate them individually. The small demo space in which I talked to the devices (that did its best to shut out the thrumming noise of the CES show floor) had at least six models active and listening for my words. When I said “Hey Emerson,” both an air fryer and one of the heaters responded. That was one of the limitations that I could see with the devices: If you outfit your entire home in Emerson Smart gear, it might take some time to name and position everything so it works in a coherent way. The lack of an app means that programmability is limited, too. That’s the trade-off the privacy-conscious or app-averse user will have to make if they want to turn their lamp on and fan up when they walk into a room just by talking. As the only offline, non-DIY voice-controlled lineup of appliances out there, you’re stuck with whatever design Emerson Smart thinks look good. Thankfully, the overall design is clean and modern, if a little basic. The upcoming models of air purifiers and fans were decidedly more attractive. A handful of devices are available for sale now, but new Emerson Smart products will go into production later this year.
