The Echo was able to pick a voice out of a crowd engaged in conversation. That means it is capable of singling out individual voice. That means it has been identifying individual voices, tagging the as “Unidentified voice 1″, Unidentified voice 2” and so on. It has already associated the voices of its owners, and if they have set up profiles for other family members, for them as well, so it knows who goes with those voices.
this is overstating the case. if you don’t believe me, have two people speak at an Echo simultaneously.
multi-speaker babble is still a major challenge in speech recognition, and speaker identification is equally hard and unsolved.
i still won’t buy one, but it’s important to be reasonable.
- lucozade 9y agoIt's not just over-stating it, it's demonstrably wrong. All you need to disprove it is to ask someone else's Echo to answer a question. What I presume it's actually doing is responding to the keyword, Alexa in this case, and somehow correlating the rest of the question to the voice that said the keyword. I don't happen to know what criteria it uses to do that but it's clearly doing that or something a lot like it. That's much less dystopian than voiceprinting the family.
- hprotagonist 9y agoThat's basically exactly what happens, except without the voice correlation part. Alexa should be easily tripped up by multi-speaker babble: speaker A says the trigger, speaker B starts a command, speaker A interrupts, and Alexa hears A+B+A. It's certainly how _i_ solved the problem when I wrote a SR system ...
