Hackaday Prize Entry: Twitter Goes To The Dogs With Raspberry Pi Hack

Dogs are remarkable creatures. Anybody who has lived with one will know that they are very vocal beasts, with barks that range from noting the presence of a squirrel in the yard to the warning whine that says “I am about to pee on your shoes if you don’t take me outside.” [Henry Conklin] decided to computerize the analysis of these noises, putting his dog [Oliver Twitch] on Twitter so he could hear what he was saying while he was at work. [Henry] that is: [Oliver] stays at home.

He did this using a Raspberry Pi, which is set to record sound above a certain volume. With the system sitting by [Oliver’s] favorite window, this records his barks. The recordings are then analyzed using PyAudioAnalysis, a library that analyzes sounds, compares them to reference ones and classifies them. ┬áThe Raspberry Pi then posts the results onto twitter using Python-twitter.

The setup used by [Oliver] to capture the barks: a USB microphone, Raspberry Pi and WiFi USB dongle.

Or rather, it will when [Henry] fixes a few bugs: right now it just posts a random string that is based on the length of the bark, not the type. [Henry] says he is working on the dog translation at the moment. It’s still a neat project that shows you how simple it is to use a few small bits of code to gather info from your environment and share these over the Internet. [Henry] also says that the next step is creating a weekly podcast for [Oliver]. I, for one, will be subscribing to hear his thoughts on how annoying the postman is, and how vexing it is to see a squirrel and not be able to chase them.

  1. The us Navy has some downloadable sound recognition freeware used in some older project for distinguishing several hundreds of whales (possible developed for classifying subs). Also there are a few university made programs around used identify individual song birds. Such pieces of software have the capability to be trained to identify different sounds (words) with A.I. recognition.

  2. So a guy has installed some software on a raspberry pi and not yet managed to get it doing anything usefull.

    I wouldn’t consider this a hack by any stretch of the imagination

    1. C’mon, he just has to fix a few bugs.

      He’s 90% done, that last 10% is just the trivial stuff that takes no time or effort at all.

      Come to think of it, we should ask him if it can launch a missile when it hears “yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap yap….”

      (Maybe after the 3rd “yap”)
      (Yap-B-Gone – coming soon!)
      (I wonder how much I can scam on Kickstarter for that)

  3. No one’s life is better who lives next door to a dog that barks incessantly.

    How about having the bark detector dial the pet owner’s phone at work? After 20 or 30 calls in a hour, perhaps the irresponsible owner will realize what a disruptive nuissance the dog has become, and the suffering inflicted upon the neighbors.
