What exactly prevents the 'hardware designed specifically for that purpose' to include in its purpose the translation of your voice to text, with voice fingerprinting for good measure? Have you ran an electronic microscope atom layer slicing of the hardware to guarantee its complete set of functionalities?

  The hardware runs an algorithm to detect the wakeword. What makes you confident that a different algorithm can't be run to translate voice to text? They will be in the same family of algorithms, just with different purposes. To make it more interesting, let's assume that 2021 algorithms can't do that. Will better low power algorithms be developed in the next 20 years? How is a democratic society supposed to work when would-be-snitches are ubiquitously deployed? To make it even more interesting, as more an more of our communications move to the internet (oooOOOooo, covid, cower in fear), what confidence you have that voice2text and voice fingerprinting does not already apply to all your phone/Zoom conversations? Do you run the phone/Zoom servers and monitor all potentially suspicious traffic? Have you heard of one Edward Snowden?

    When you train your phone to understand "Hey Siri" it requires an internet connection for the training so that it can verify that you are actually saying, "Hey Siri" and not "Yo, phone spirit". After the initial training, it no longer requires (or uses) the internet to detect the keyphrase. You are asked to do a few iterations of training so that the phone has a model on your voiceprint for "Hey Siri". Which is why, when someone who does not have a similar voice to you says "Hey Siri" it does not trigger. But someone who does have a similar voice to you can sometimes trigger it. The model is super basic. The microphone is always passively passing input data to the "Hey Siri" detector (and a buffer), which acts as a sort of internal switch. If it detects the trigger phrase, it then sends the audio data to the cloud to be transcribed, and acted upon accordingly. It is not always sending voice data to the cloud. If it were, your battery life would be noticeably impacted - worse than being on a phone call.

      Good explanation, thanks. The scenario is 'translate on device, steganograph the output on background traffic'. There is a huge push for 'on device ML', driven by noble intentions of hiding raw data from Skynet. Alas, the end of that road is devices that compress the raw sensorial input and report, possibly stealthily, the digest to Skynet.

      This explanation does not explain why neither Google nor Apple allow you to change the wake word. Myself, I believe any technical reason, if it actually exists, is a secondary factor - the primary reason is branding. They don't want people changing wakewords, because as long as everyone uses the same, "Ok Google" and "Siri" are terms/brands.

        To my understanding, there is no technical reason behind not being able to use custom wakewords besides them just not wanting you to. I also believe it is restricted mainly for branding and easy marketing.
