Amazon’s vision is of homes with Echo devices in every room, listening to every word you say.
Eavesdropping appliances like Amazon Echo and software assistants like Google Now can be attacked using mangled words that get interpreted as commands, but humans hear as nonsense.
Playing 'natural sounds' affected the bodily systems that control the flight-or-fright and rest-digest autonomic nervous systems, with associated effects in the resting activity of the brain. When listening to natural sounds, the brain connectivity reflected an outward-directed focus of attention; when listening to artificial sounds, the brain connectivity reflected an inward-directed focus of attention, similar to states observed in anxiety, post-traumatic stress disorder and depression.
Happy memories spring to mind much faster than sad, scary or peaceful ones. Moreover, if you listen to happy or peaceful music, you recall positive memories, whereas if you listen to emotionally scary or sad music, you recall largely negative memories from your past.
Keystroke sounds, or acoustic emanations can be recorded during a Skype voice or video call and later reassembled as text.
Unlike Apple or Amazon, selling things to consumers has never been Google’s primary game. Google uses A.I. to understand people’s language and intent (as in search queries) and to customize its products to their habits and preferences (as with Nest thermostats, Inbox Smart Reply, or Google Calendar’s Goals). It then harnesses this knowledge to target users with advertisements.
The rhetorical content varies greatly, but US presidential candidates modulate their voices in the same way when faced with different audiences. When addressing other leaders the researchers found that the speakers varied their pitch from very low to medium, eschewing high frequencies altogether. This pattern of use is also found among other mammals, where lower frequency voices often reflect physical size, power, or dominance. In more casual settings they used a "healthy" voice, or the normal, non-varying voice they use to speak with their families.
Higher fundamental frequency, greater pitch variability, and increased vowel space -- which is related to the size and shape of the vocal tract -- are all correlated with an increased perception of femininity.

Our gray matter evolved to forget things; otherwise we’d have the images of every face we saw on the subway rattling around our head all day long. Yet we’re building computers with the capacity to remember everything. Everything! And we might one day hook these devices to our brains. Find out what it’s like – and whether it’s desirable – to live in a world of total recall. Plus, the quest for cognitive computers, and how to shake that catchy – but annoying – jingle that plays in your head over and over and over and …
A century ago, Albert Einstein rewrote our understanding of physics with his Theory of General Relativity. Our intuitive ideas about space, time, mass, and gravity turned out to be wrong. Find out how this masterwork changed our understanding of how the universe works and why you can thank Einstein whenever you turn on your GPS.
Today we value qualities like clarity—how it makes a modern orchestra sound, whereas prior to sound wave theory, echoes were considered mysterious and divine.
You’re a private person. But as long as you’re on-line and have skin and hair, you’re shedding little bits of data and DNA everywhere you go. Find out how that personal information – whether or not it’s used against you – is no longer solely your own. Are your private thoughts next?
Hubert Reeves a gardé intacte sa passion de la connaissance, virus contracté dans son enfance canadienne, sous les étoiles. Il reçoit les Racines du Ciel dans on appartement parisien, sur fond de musique classique, l’œil malicieux, l’intelligence en éveil et l’humour en prime. Il nous raconte tout simplement ces passions qui l’animent depuis toujours. Il nous dit comment il voit le monde, pourquoi il faut s’engager dans le grand combat écologique et s’impliquer contre toute forme de violence : violences faites aux hommes ou à la nature. La science est chez lui, encore et toujours source de sagesse, et la beauté du monde source d’émerveillement. Ce sont cet émerveillement et cette sagesse qu’il partage avec nous, en veilleur et en inititiateur.

Playing natural sounds such as flowing water in offices could boosts worker moods and improve cognitive abilities in addition to providing speech privacy.
Being in a position of power can fundamentally change the way you speak, altering basic acoustic properties of the voice, and other people are able to pick up on these vocal cues to know who is really in charge, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
