My experience with Sphinx is, a lot of Type II errors. That is, it does great recognizing voice commands from a small grammar, like "dial 911". But it would recognize background noise/background television as voice command, too. It's a bad outcome when one of the actions is "dial 911".
There's a lot of complaints about Alexa doing that. Unless it's able to distinguish your voice from someone else's, that problems not going to go away. There's plenty of YouTube watchers complaining about whenever some YouTube personality says "Alexa, switch off the light," their own Alexa does it.
I don't have any of those spying devices, but when I try speech control on my phone, it's very poor at recognising what I say. I notice Samsung's one is much better than Google's, but I could only use Samsung's to do something like dictate a SMS. I can easily just use a messenger app that just lets me send a recorded sound bite. It's also a right pain to work out what command it expects you to use to do what action. I prefer actually using real light switches, anyway.
