Voice speakers like Amazon Echo maybe a fad like motion controls like Microsoft Kinect, and Playstation Move. I think the voice commands in Xbox Kinect are rarely used these days. There are news stories of Voice commands causing a lot of problems, and causing privacy concerns. There are people who accidentally use them, and they don't seem to save much time compared to using a keyboard and mouse to use a device. I read articles that people are accidentally using voice commands to search for stuff online, a TV or video commercial activated their speaker to search for something. There was a news story of a man who accidentally called the police because he said "Did you call the Sheriff on me? to his wife". I feel a PC with a microphone, and smartphone or tablet is already good enough for doing voice searches from an app, website, or program. PC and smartphone/tablet users can choose to use different voice command programs, apps, and websites without being stuck to only using Amazon Echo, Siri, Google Now, etc like Voice control speakers made by Amazon, Google, or Apple. It is also easy to hook up a headset mic on a PC and smartphone, so the voice commands maybe more accurate because headset mics are closer to a person's mouth. There is not a real need to buy a voice control speaker which is always ON and listening, using electricity, and connected to the internet when most users can use their PC or smartphone for voice search, and commands. Plus, I find using my keyboard, and mouse a lot faster for looking up information online, and using programs because I can use keyboard shortcuts like CTRL-V/Paste or Ctrl-C/copy, use bookmarks on web browsers, or just save a website for viewing offline.
