Google Research prototypes ambient audio contextual content

Marshall Kirkpatrick

150 comments »

A team from Google Research has developed a prototype system that uses a home computer’s internal microphone to listen to the ambient audio in a room, determine what is being watched on TV and offer web-based supplemental information, services and shopping contextual to each program being watched. It’s strange, but it sounds like it works and people might really like it. There’s no indication yet whether or when this could be available as a service.

Google Research team members Michele Covell and Shumeet Baluja along with Michael Fink of the Hebrew University of Jerusalem’s Center for Neural Computation were given the best paper award for their report on the system at the the Euro ITV (interactive television) conference last week. (“Social- and Interactive-Television Applications Based on Real-Time Ambient-Audio Identification” 10 pg PDF, see also the Google Research blog post on the paper.)

The system compresses the captured audio into irreversible (emphasis theirs) summary statistics which are then compared to a database of mass media statistics and used to determine what the browser should display. Possible service offerings discussed in the paper fall into four categories:

  • Personalized information layers Here’s what Tom Cruise is wearing in the show you are watching and here’s where you can buy the same clothes in your zip code.
  • Ad hoc social peer communities If you would like to chat about this show, ten of your college friends are watching it right now as well.
  • Real-time popularity ratings Nielsen requires hardware and the results aren’t available in real-time. You might want to know if there is a spike in viewers watching the show on channel 9 right now. Advertisers might want to know that too.
  • TV- based bookmarks Click to save a show or clip into your video library and there will be more than just a few shows available for watching later.

The system requires no dedicated television-connected hardware, protects users’ privacy and is technically feasible, the researchers report. Experiments with a laptop placed in the lap of a person ten feet from a television and engaged in loud conversation with some one next to them were successful in providing matching online content - when channel surfing was taken into account.

Lest you fear that all broadcast TV is a huge data-set, the report says that ff the database of summaries holds only 32-bit descriptors of 5 second clips, then up to one year of broadcast information could be held in less than 1 GB. The researchers report that this is made much more feasible by re-runs.

Privacy concerns were addressed in the prototype by compressing captured audio on the user’s computer before transmitting summary data to the database for comparison and by offering a mute button in the program. Given Google’s recent ethical issues, these privacy measures may not be enough to assuage some people.

    Is google crazy?!? I can’t even imagine what this current project would make the privacy advocates say. Letting it hear us over a mike, and then making ads? This is giving me the creeps, and I have no intention in allowing 1984 style loss of privacy coming any quicker that it already is. I can see this information being used for good, but in the hands of the wrong people. Oh my god! What if the government is successful in subpoening google for information? So, now apart from phone calls, they literally tap into our living rooms, and hear our conversations.. Absolutely not!

  2. Steve

    This sounds interesting and cool but good point Joy, that would be scary.

  3. Erik Schwartz

    The NSA will just love this.

    You don’t even need to sneak and an plant bugs in order to wiretap someone now.

  4. John B

    Great!!! Another way to get more, better spam!!! More ads, consumers rejoice?

  5. Will

    I agree with Joy. Aside from the other obvious issues with this idea, users are increasingly aware of the need to preserve and protect (what’s left of) their privacy online and unless the benefit overwhelmingly outweighs the cost are unlikely to have it wrested from them in the interest of “supplemental content” of dubious value (really — who cares where Tom Cruise bought his jaunty top? And the social thing — people have already found ways to self-organize around shared-viewing experiences that seem to work well…) I guess I just don’t see how organizing the world’s information and making it accessible includes spying on the world’s users and blatantly disregarding the basic right to privacy in one’s own living room to (and let’s not kid ourselves here) sell ads.

  6. prayag

    From technical stand point great idea and out of the box thinking. But from the consumer stand point, if I love my DVR, why the hack do I want google to serve me add based on what I am watching. For F*** sake T.V is for the entertainment and not for Google to listen to what I watch.

  7. Serdar

    Why stop with TV? Google should train their system to listen in on everything that goes on at home and serve ads as necessary. V*agra! Ritalin! Divorce lawyer! Metamucil!

  8. Marshall Kirkpatrick

    Serdar, I think you win the funniest comment so far award. Tough competition though.

  9. Frank

    This is really scary. Google is set to invade its users privacy now more than ever before. F*** that!

  10. roth

    Like it or not this type of internet technology is only the beginning. Good for Google to be the first to wet their feet. And for those that think i’m crazy. Think about it this way. Ten years ago the internet was a 2400 modem. Not to mention text based only internet. Irc became chat. Text based pages became web 2.0. I could go on and on. You get my point. Hold on for major life changes.

  11. Marshall Kirkpatrick

    To be fair, the research paper says that conversations will NOT be listened to, they will be filtered out. The audio data will be compressed to represent the TV shows while it’s your computer before it’s transmitted to Google. They say it several times throughout the paper.

  12. Steve Macdonald

    Thought it was a post from The Onion.

    “but it sounds like it works and people might really like it”

    Breathtaking naivete. How old are you? 17?

  13. Marshall Kirkpatrick

    Steve, I think there is ample evidence that many people would welcome a system like this and would accept assurances that they are not being spied on.

  14. JakeBrake

    Just disconnect the microphone or eat gobs of beans and fart to mask the sounds if leaving your mic live. Of course you risk getting ads about these:
    http://health-beauty.search.eb.....acatZ26395

  15. Melvin Ram

    Sounds like they want to dip their toe into TV ads. They’ve got video ad capability added to Adwords and it sounds like this would be excellent to integrate into that. I doubt this will make it to even open beta.

    What they could do with it is go to ABC or NBC and propose contextual advertising for TV shows (which I’m guessing they already have done or have plans to.)

    Just having technology that would let them by-pass the TV stations probably gives them some leverage. From the little I know bout the media industry, they’ll need every leverage they can get.

  16. Jonas

    What a great media supplement. Heck im in front of the tv right now and on my laptop. I bet this type of interaction will be hot with the consumer.

  17. RBA

    “I have seen the future… and it sucks”.

    Could someone please draw a better future for us, humans? I mean… consumers?

  18. IDunno

    So if you’re wheezing will you get a lot of porn ads?

    Beating your spouse? Ads for guns!

    I’ll reserve judgement until I can test this out… until then, typical overreactions being seen.

  19. met

    For people watching their programs on a media center PC this roundabout method can be replicated with a widget for sideshow.

    I think Bill Gates Keynote did show something similar at Las Vegas (whatever show that was).
    They demoed something similar for HD-DVDs, too.

  20. Karthik

    Google will push a lot of its ads into that if it becomes available as a service! Makes ‘ad’ sense.

  21. Simran

    Google is getting CREEPY. From holding alll your data on GDRIVE to recording your emails and chats. I’m starting to get wary. Now they’ll have all my conversations and are going to keep records of everything I watch on TV? I forget, they also have records of everything I’ve searched for and all my research notes. And let’s not forget all my blogposts and calendar items and address book, so they know where I’ll be when and who I’m meeting and why. Are we sure we can trust an entity with so much information to stick to its motto of doing no evil? It’s been proven time and again that people and entities with power misuse it. Oh and they also know exactly who I’m meeting and chatting with on Gtalk and Orkut. They have my picture on Orkut, every personal detail of mine and what I think is a perfect date. Oh, now I know why Ms. Jr. Page was able to seduce me the other day! She knew I liked walks on the beach and tequila!

  22. caw

    Wow.. that’s almost content theft on a massive scale.. So Channel4 (UK) spends a few million quid licensing Lost so they can make a packet on advertising, and the big G displays advertising all the way through it for free… I think I’ll go into my local hypermarket and stick stickers over all the beer cans for a site I own…

    Hats off for innovation though!

    PS - wouldn’t it have been much simpler to have a web page that said ‘what channel are you watching’.. that’s 1 button click… hell, maybe we should do that instead, then scrape G through the API and display TextAds on the content.

  23. Marshall Kirkpatrick

    caw - I think you’re missing the point - people have to be able to passively enter into the active phase of TV watching :) Clicking your channel number is too much effort to ask from someone in order for them to enter a live chat they are honestly interested in. (For our international readers visiting right now- in case it’s not clear, I’m totally being sarcastic.)

  24. caw

    Dang, you’re right.

  25. patrik

    Well, so the Google Labs reinvented, what “Radiocontrol” already does for years…:
    http://www.radiocontrol.ch/english/home.html

  26. Dan

    Clever stuff … but ultimately doomed technology. With the merging of TV and internet (and radio) technologies it will all come through the same connection anyway eventually, so no need to ‘listen in’ - the data will already be logged.

  27. bored

    Between this and Google’s FireFox browser sync tool (http://www.google.com/tools/firefox/browsersync/index.html) storing info on Google’s servers, I wonder if anyone is going to discuss privacy issues today? ;-)

  28. Tijs

    This research ties in nicely to Cringely’s prediction that google is poised to take up video distribution (with included tv advertising model):

    http://www.pbs.org/cringely/pu.....60105.html

  29. Harry

    But this is like sticking a web cam so that Google knows what site we are visiting! I mean, why a mic? With IPTV, it will not be an issue to get to know what each home is viewing. Is that the expiration date of this product?

  30. seekXL

  32. Paul

    I think some of you are being complete jackasses. How many comments do we need about Google serving ads based on our conversations and the sounds of our actions, after it has been established that these noises are to be filtered out, for the point of the technology: to serve ads contextual to what you’re watching on TV.

    What’s with all the bitching about Google knowing everything about you? Don’t use their products then! All I’m seeing here is the inevitable. And it’s cool.

  33. Vijaychandran

    Why cant google start an online ad making agency.Needless to say hottest in town. They can claim that they know the customer than any one because of tons of datas and clicks they can claim.

  34. Darren McLaughlin

    When a company has an insane stock valuation, insane proposals start becoming accepted as reality. I cannot imagine any scenario where I’d give a company access like this (especially Google Inc.).

  35. Paul Fabretti

    Awesome…bring it on. I’d be glad to be aguinea pig for this if it meant that audio (and the video) could be searchable items on google.

    This has GOT to be the next big thing. With podcasting growing so much, imagine being able to search audio and download sections only relevant to what you want.

    Despite the cliche about Google-Love this is a massive step in the right direction for me.

  42. lee

    I recall radioshack doing a similar form of home privacy invasion about 5 years ago with the cuecat bar code reader. Among the various similar give aways they offered a device that attached to your tv directly (i suppose ambient is enough to differentiate this as a new idea in the US’s defunked patenting system) and intercepted the audio linking you to the particular product on television. Unfortunately this was a little before widespread broadband integration and as you know never caught on. But thanks google, your love of feeding the ad machines whille playing us like pawns fed by cool techy services is what keeps the internet fresh (and your pockets loaded).

  45. William

  46. Bob Wyman

    Just a few days ago, Microsoft was awarded a patent on a system for monitoring “television programming” and inserting ads in content on computers as a result of that monitoring. i.e. The ads you see on web pages will be sensitive to what you watch on TV… see: http://patft1.uspto.gov/netacg.....er=7051351

    The Microsoft patent covers the case where “the client system has access to television programming viewed by a user of the information retrieval system.” The claims are not specific about the means by which “access to television programming” is achieved. The description clearly anticipates some kind of physical connection to the television device, however, the claims would appear to be written broadly enough so that picking up “ambient noise” might constitute “access to television programming.” The Google approach, being more general than the Microsoft patent, might still have a problem if it is used to do what the more constrained Microsoft system claims.

    Thanks for pointing that out Bob, that’s really interesting. I wonder how people would have reacted if this was a story about MS instead of Google.

    Thanks Marshall (Comment 47). If you’re interested in this type of patents, you can find lots more at http://www.uspto.gov. Here are a few more recent Microsoft patents concerning various means of implementing advertising spyware:

    Trust Google. They are good people. They don’t do evil. They will certainly filter out your conversation from your response to television shows (think for a second of how that might even be possible.) Google will make the world a better place by providing more information about you to advertisers. You will have more choice of what products to buy, what presidents to vote for and what manufactured reality to live in.

    Open your eyes.

  53. Dave

    Don’t you hate seeing all these car ads……after you bought your new car. Same goes for barbeque … etc.
    So if you are watching tv and they think you are interested it a new car or barbeque is that the ads you will get?
    In an ideal world I could surf the net for just what I want to buy and find the bet price.
    Whoa…. I can do now. Guess we may not need a mindreader afterall.

    I have one thing to say here. After reading this page and it’s replys.

    I AM A VICTIM OF THIS TYPE OF TESTING. And i hate it all it has done is drive me away from my pc. and it has a unease feeling about it. This is not good. i feel as if my home has been broken and entered. i wouldn’t mind if i was told and it was an open beta but like this ! not nice at all.

    that is too creapy!

  57. Murali N. Rao

    Google can sell (for free) sunglasses with a buildin camera and can track what we see outside of our PCs and can popup ads when we get home.

    I am sure google’s legal team and their researchers will come up with something to protect our privacy. I heared that you can distinquish between a audio created from TV Vs people talking. So, they can just trap only our TVs.

    To protect your privacy:
    1. Switch off the pc when not in use.
    2. Use your tv’s “Closed Caption” and “Mute” functionality.
    3. Windows users, install the latest sound drivers (beta is preferred), which will anyway disable the sound system.

  58. Galdren

    Calm down people…as you can see it is a seperate page that you have to visit, and since it’s in your browser, they’ll probably need you to accept the activex/java/whatever module before they can run it on your pc…

    it’s really your own choice

    and before starting to point fingers at google because they’re big and mighty…do you realize that ALL windows applications including windows itself are not open-source, which means that probably none of you actually knows what your windows operating system is doing while you’re online..

    if you’re scared software will abuse information you give to it, you better uninstall windows and start using linux

  59. Tjerk

    Proves jst one point: Google is not, i repeat IS NOT, a search engine. It is an advertising trap.

  60. Marijn

    William (comment 45) made a point. Privacy is not the issue (anymore). Why do companies assume that i wanna ‘buybuybuy’ everytime i visit internet? The sole purpose of internet was to provide FREE acces to information and data for everyone. Not being a huge billboard for companies. If i wanted such, i would turn on the T.V. !

    I have trouble believing this will ever happen.. too many privacy issues

  70. JoAnn

    This abhorrent breach of one’s privacy is outrageous. I have already deleted Google toolbar and switched my search engine. I will not take a chance now or in the future to have my privacy breach in such a way not only be Google but by any one else or any other organization using such a program. NOW, the question is, how do I disable the built in microphone on my computer. I just watch a report regarding Google ears on CBC (Canadian Broadcast Channel) and the man being interviewed did say that people will NOT be able to opt out and there is a possiblity private conversations could be picked up. I don’t care if I’m talking to my cat about her fat belly, I do not want anyone listening in without my knowledge or consent. I have a Dell computer if you know how to disable the microphone please post instructions. Thank you. JoAnn

  71. 2Much

    Google is going too far. Their reasons to listen to ambient noise in our homes are lame!!! I do not intend to be listened to in my home. I am getting in contact with the office of the privacy commissioner of Canada to file a complaint under the Privacy Act. I hope others will do the same.

  72. Bob

    Hey Google, good luck with that here. All computers in the household either don’t have microphones hooked to them or, in the case of laptops, the mic input is muted.
    I’ve pretty much been trusting of Google…until now.

  73. fucks_google_in_mouth

    Hey guess, what - no more Google in this household. I bet Google’s market share, which eroded from 80% in 2002 to less than 45% in 2006, will be under 25% by 2008. Bye Bye Buggy Whip.

    The company, which was spun off from a Carnegie Mellon University project in 2001, announced this week the AKU2000, a single-chip microphone that can be produced on standard silicon processes. Ultimately, the chip could lead to better voice quality on Skype phones embedded in laptops, for example, or sharper, more distinct sound on video captured by digital cameras.

    A few Asian laptop manufacturers may begin to offer notebooks with the chip in a few months, said Akustica CEO Jim Rock.

    “If you are serious about VoIP, you need to offer a digital microphone,” he said.

    Microphones in laptops, cell phones and MP3 players/voice recorders are largely Electret Condenser Microphones. ECMs are analog devices, which mean they capture real-world sound waves with a membrane and transmit them to an analog-to-digital converter. To prevent signal interference or noise, ECMs have to be insulated from wires and components.

    The membrane in the AKU2000 is one of the metal layers of the chip. (Chips are made up of layers of silicon and metal.) An integrated analog-to-digital converter then turns the captured vibrations into a digital signal. The entire microphone is contained on a single chip–a first, according to the company.

    With the digital microphone, interference is less of an issue, meaning the chips can be placed more freely inside a notebook or cell phone. Two to four of the chips can be embedded into the bezel of a notebook, for instance. The first notebooks with Akustica’s product will likely have two chips. With more microphones, sound quality improves.

    “You can focus better on the speaker and get rid of noise,” Rock said.

    The AKU2000 takes up less space than traditional microphones because additional components for preventing signal interference aren’t needed.

    The basic chip technology may also be used one day to make accelerometers, be incorporated into car-braking systems or be built into different types of communications chips.

    The difficult part, at least for now, is the price, noted Allen Nogee, an analyst at In-Stat. “It is not the cheapest microphone on the market,” he said.

    Akustica’s chip will sell for $3.76 in quantities of 1,000, while conventional microphone chips sell for $1 or less. Still, Rock said the price difference is actually rather slight, because most customers will order more than 1,000.

    “We’re talking 50,000 and 100,000,” he said.

    A system recently outlined by researchers at Google amounts to personalized TV without the fancy set-top equipment required by previous (and failed) attempts at interactive television. Their prototype software, detailed in a conference presentation in Europe last June, uses a computer’s built-in microphone to listen to the sounds in a room. It then filters each five-second snippet of sound to pick out audio from a TV, reduces the snippet to a digital “fingerprint,” searches an Internet server for a matching fingerprint from a pre-recorded show, and, if it finds a match, displays ads, chat rooms, or other information related to that snippet on the user’s computer.

    Someone want to clue me in to the built-in microphone in every PC? I’m guessing some laptops have a built-in microphone, but how about desktop computers? Desktops usually have a microphone port on the back of the motherboard which you can hook up a mic, but is there another surface mount microphone on the motherboard itself? Anyone heard of this?

    Google Using Your Mic to Listen In?
    Then feeding you ads based on what they hear…

    A strange story in the Register this morning that suggests the search giant is working on technology that would listen in on ambient noise via a user’s PC microphone, then deliver contextual ads based on what was heard. Google apparently promises that the service only listens to music or TV noise and bases the ads off of that, but privacy implications are so far reaching that it’s hard to believe this idea has any real traction.

    Voice Over Internet Protocol and Skype Security

    Simson L. Garfinkel

    With the increased deployment of high-speed (“broadband”) Internet connectivity, a growing number of businesses and individuals are using the Internet for voice telephony, a technique known as Voice over Internet Protocol (VoIP). With a VoIP system, two people can speak with each other by using headsets and microphones connected directly to their computers. Skype is a proprietary VoIP system developed by Skype Technologies S.A. Like the popular KaZaA file-trading system, Skype is based on peer-to-peer technology: instead of transmitting all voice calls through a central server, as some VoIP services do (Vonage, for example), Skype clients seek out and find other Skype clients, then build from these connections a network that can be used to search for other users and send them messages. Is Skype secure? How does its security compare with that of conventional telephone calls, or of other VoIP-based systems? In this article commissioned by OSI’s Information Program, Simson Garfinkel, an expert on Internet security and networking issues, looks at the security properties of key importance for civil society organizations relying on Skype for voice communications.

  77. the truth

    every phone in the world is an active microphone into your home. the phone can be “on-the-hook” and still transmit sound to anyone with the capacity and desire to listen. check out the FoxNews reports on Comverse’s (an Israeli company) widespread spying on and in the U.S.A and see the 2006 film ‘The Listening”

    Google at least has the class to be upfront about their spying
