That sounds impossible to do on audio alone. How in the world do you tell what sound is directed at a person vs just coming towards them normally?

- qroshan 7y agoWell if you have enough personal data about who speaks to you in what tone and at what context, you can tell. Definitely not impossible

- adwi 7y agoMaybe some combination of: comparing average recent audio levels and detecting a sudden spike in the average human speech frequency range, using far field mic tech these companies have been focusing on to check against direction the audio source is coming from (ie, only focus on someone right in front of you), maybe auto adding the first name of the phone owner to a watch word ala “hey Siri”, etc I’m not an expert at all on the “how”, just thought could be a useful “what” that solves some friction with current tech (similar to how these automatically adjust noise cancellation settings vs needing to set manually as with competitors)
