A potential customer requested a feasibiltiy study for a product
requiring detecion of dog barks in a real-time recorderd digital audio
signal. Functional requirements describe:

"Barks should be detected with a accuracy of at least 80%, while other
(possibly loud) signals like traffic, playing children, etc should
generate false positives in no more then 10% of the cases."

Any tips on algorithms or literature to get me started ?

Thanks,

Ico

Dog barks differently depending on they are hungry or angry.
I love dogs.

Barks in general, or a particular dog? Even a relatively narrow range of
breeds would help. Given the yip-yip of a Chihuahua, the baying of a
beagle, or the booming bass of a Great Pyrenees, I don't see enough
common underlying structure to distinguish a dog from an odd motorbike.

Hello Ico,
Wow, that sounds like an interesting project.
Your problem, I believe, falls in the category
of "signal recognition" (a topic of which I'm
shamefully ignorant). I wonder if some of the
techniques used for human "voice recognition"
might be applicable to your problem. My guess
is that your "barking detection" problem is NOT
an easy problem to solve.

It would be interesting to look at the time-
domain, and frequency-domain, plots of an audio
barking dog signal.

Concerning the barking of my neighbors' dogs,
I'd be willing to work on this project for free
if it included: (1) detection of dog barking,
and (2) upon detection, application of a severe
electric shock to the rectums of my human neighbors.
