In one Amazon patent, a device with the Alexa assistant picks up a woman’s speech irregularities that imply a cold through using “an analysis of pitch, pulse, voicing, jittering, and/or harmonicity of a user’s voice, as determined from processing the voice data.” From that conclusion, Alexa asks if the woman wants a recipe for chicken soup. When she says no, it offers to sell her cough drops with one-hour delivery.None of this is surprising. I was working on this stuff in academia in the '80s. At the time I didn't foresee the evil reality. After I caught the shadows of NSA working in the same areas and sometimes subsidizing the academic side for replication, I shied away from that line of work. It could have beneficial uses, but frankly the beneficial uses haven't materialized. Only the Deepstate uses.
