You'll note that "OK, Google" works when your phone is on flight mode. Google aren't constantly sending your microphone data to their servers, the recognition of that phrase happens on your device.

Wake word recognition happens on-device with Alexa as well.

Yes, they can't constantly send microphone data even if they wanted due to power constraints. They use a dedicated DSP chip with the sole purpose of detecting the hot word.

  then stabb the mic afew dozen times, and feed the hotword to the DSP with a button, or better yet use another DSP to bridge your own custom interface to the "hotword sniffer" typing to an alexa device should be an option, just like having an AI chat.

Mine was activated many times in the past when it shouldn't have been, e.g. while watching TV (no, nobody said "OK Google"), and my mom has a tendency to somehow activate my phone by just talking... Once it is activated, it starts recording and sending audio data to google. Every such device has a false positive rate on keyphrase activations, and of course the do, there is only limited processing available in those phones (that also try to conserve power), and people tend to mumble sometimes so you have to be a little generous and balance false positives against false negatives - the latter of which people refer to as "shit don't work". Devices in lawyers' home offices aren't any different. And if the device encounters a false positive and activates, somewhere on some server some recording of your confidential conversation may get stored. Or worse, you buy 100 copies of "The Art of the Deal" off amazon by accident. Even worse if your client's name, or their wife's or mom's name, is Alexa... or Alexandra/Alexander, which also cause a lot of false positive activations, or so I heard from a friend of a friend with that name.

  My little brother's name is Alexa (not short for Alexander, just Алекса/Alexa). There are no Echo devices in the household to say the least. I do like to joke "This is so sad. Alexa, play Despacito" :)
