Would you consider the device "listening" if a DSP is listening for a particular hotword, but no audio data is being uploaded?
I'm pretty sure that's what happens in either case, whether you're using Alexa, Siri, or Google Assistant, and whether it's a "home" device or a phone with hotword detection. I used to work at Google on some related hardware projects.
If you're suspicious because the home devices seem much more accurate, that's because they have microphone arrays which can facilitate beamforming.
- tjoff 8y agoYes. There have also been issues of google devices accidentally recording constantly. And then "accidentally" stream it to the cloud. https://www.gearbrain.com/google-home-mini-recorded-everything-2495445625.html https://www.gearbrain.com/google-home-mini-recorded-everythi... The level of safe guards google et al put in to deal with stuff like this are incomprehensible poor. The accuracy is irrelevant.
