NASA Develops Tech To Hear Words Not Yet Spoken 466

Posted by simoniker from the what-am-i-thinking? dept.
alex_guy_CA writes "Yahoo News has a story about technology that comes close to reading thoughts not yet spoken, by analyzing nerve commands to the throat. 'A person using the subvocal system thinks of phrases and talks to himself so quietly it cannot be heard, but the tongue and vocal cords do receive speech signals from the brain,' said developer Chuck Jorgensen, of NASA's Ames Research Center, Moffett Field, California. Jorgensen's team found that sensors under the chin and one each side of the Adam's apple pick up the brain's commands to the speech organs, allowing the subauditory, or 'silent speech' to be captured. The story indicates the method could be useful on space missions or other difficult working conditions."

        This technology doesn't detect thoughts, it detects subvocalization. You don't normally subvocalize when thinking to yourself; it takes a conscious effort similar to talking out loud.

    • Actually, I remember reading about that technology being used in the Fifth Foreign Legion trilogy.

      There's this thing called LASH... I forget exactly what the acronym means, but I think it means, Los Angeles Silent/SWAT Headset. It is basically a collar that goes around your throat, and you mouth the words you want to say, and everyone else with a reciever can hear them. You don't whisper, you just silently make the mouth gestures and the machine amplifies them. Perfect for a SWAT team, or pretty much any military force.

        LASH uses a throat microphone. It straps to the throat and you have to speak (make noise) for the microphone to pickup. The advantage of a throat microphone is that ambient noise is not picked up by the microphone. According to one of the vendors ( swatheadsets.com [swatheadsets.com]) you are supposed to be able to be understood through the microphone while under the beating rotors of a helicopter.

        One disadvantage is that percussive sounds (In english, the sound of a "B", "T", "D" etc.) are not picked up by most throat mikes because these sounds are made mostly by the lips, not the throat.

      It should not be too much of a problem once people get used to it. And it shouldnt be too much more difficult than to control than actually (vocally) talking without thinking.
      Humans right now are trained to keep their mouth shut even when they are thinking, or even talk exactly opposite of what they think. We yet are not used to controlling the previous level, ie subconsciously talking (ever noticed people at bus stops muttering to themselves or even smiling?) .Once this technology has become mainstream, we should be able to adapt and to think only at a brain level instead of translating into vocal commands. (Qustion: Do Spanish people think differently from Chinese people who don't have a proper phonetic language if they are thinking to themselves?)
      And I think we have done this before. Imagine a non-humanoid alien landing on earth. I am sure he would be surprised that all the humans can actually balance themselves on 2 foot and even run around (They would probably think it a waste trying to balance yourself on a point while crawling is much less brain intensive). And Imagine, these beings can even balance themselves on 2 inch thick wheels around a metre above earth (bicycles).And this technique has no evolutionary basis, almost all the humans learned it within a 100 years or so. Looks like a very adaptable race to me.

          Is abstract thought possible without language?

          Yes. How could one aquire language if thought wasn't there already? Consider the rare feral children adults who have grown up without acquiring language [wikipedia.org] - do you think they're "dark inside"? Or even more fascinating, Helen Keller, who acquired language late enough to have memories that pre-dated that acquisition.

          Consult any Zen master for further instruction - that which the Japanese call "mushin" ("no-mind") might be thought of as "thinking without words". (Of course, there is a difference between transcending linguistic thought, and never acquiring it in the first place.)

          But in thinking of mushin as thinking without words, you are thinking with words, and thus getting away from the actual phenomenon. Thus Zen Master Seung Sahn's observation "open mouth, already a mistake" [cizny.org].

          Man is a thinking reed but his great works are when he is not calculating and thinking. "Childlikeness" has to be restored with long years of training in the art of self-forgetfulness. When this is attained, man thinks yet he does not think. He thinks like the showers coming down from the sky; he thinks like the waves rolling on the ocean; he thinks like the stars illuminating the nightly heavens; he thinks like the green foliage shooting forth in the relaxing spring breeze. Indeed, he is the showers, the ocean, the stars, the foliage. -- D.T. Suzuki

    • Try sotto voce (subvocal) whistling instead. If you use the speech parts of the brain, it's quite easy to slip up and say something you didn't intend. If you whistle, it's very difficult - if not impossible - to accidentally say anything; you have to stop whistling first, switching focus from your mouth (which is where the whistle is generated) to your vocal cords (for speech.)

    There are times when we think in complete sentences, and times when we just rely on non-verbal thinking. Generally, the more planned the act, the more likely that complete sentences pass through your brain.

    For instance, you're more likely to simply pick a quarter off the floor than to say, "I am going to pick this quarter off the floor." Whereas, you're very likely to think the sentence, "I should buy some wine on my way home from the market" if that's part of your plans.

    Seems to me that this technology could, in short order, discern the verbal sentences we fashion for ourselves as part of our daily thinking. But it won't ever pick up on the million thoughts we have each day that aren't based on words.

    If this technology gets deployed, society will have to learn in short order that not every thought is legitimate. My verbalizing the thought to myself, "I am Napoleon" does not necessarily mean that I think I am Napoleon.

    One last thought. If we get widespread, cheap deployment of this technology, it will have as big an effect on our lives as the World Wide Web.

    • I have no idea what you are talking about in reference to a transformers toy, but what you described sounds a whole lot like a 60s voice box. These were popular for a while (hey man, the guitar is talking to me), and were comprised of a speaker connected to a tube, which you put in your mouth. The sound would come out of your mouth, and depending on the shape of your mouth at any given moment distorts the sound (frequency and volume wise).

    .. not what you think is printed before your eyes get around to reading it.

    "A person using the subvocal system thinks of phrases and talks to himself so quietly it cannot be heard, but the tongue and vocal cords do receive speech signals from the brain,"

    Notice the phrase "..talks to himself so quietly.."?
    This is NOT the same as "thinks to himself"

    i.e.you mouth the words but don't blow air through your airway so no noise is made.

    it's not friggin' mind reading..unlike most of the level 5 posts seem to think.

    • Ugh, dude...

      You might want to read the article again.

      "Biological signals arise when reading or speaking to oneself with or without actual lip or facial movement."

      Notice the part that says "without actual lip or facial movement"? So we have, "talking to yourself", and "no lip or facial movement". That sounds a lot like "thinking to yourself" to me.

    As another poster mentioned, in OSC's Ender novels, as well as in David Brin's _Earth_. As a matter of fact, the latter described the device almost precisely as described here. Brin even thought of some important caveats: given how difficult it is for the average human being to keep their thoughts on track for 0.2ms, the thing is almost impossible to use for more than 0.3ms. (The extra 0.1ms is the length of time it takes to think 'FORKING PIECE OF SHI.zza!@EOF' as you reach for the sensors.)

    Simply take a vocal sample of the person of interest. Now think your words and with a little quick signal processing out comes the voice of the person of interest speaking your words. Fun at parties and for police mounting "sting" operations. Possibly could render recorded conversations inadmissible as evidence.
