I speak English. Super well. And I can read the rough, overall vibe of writing in French. I can also order beer and taxis in Spanish. Alas, my dog can do none of these things, and we are left in communication limbo. I try asking them (in English) why they’re so mean to that one Cockapoo who lives across the road, or why they don’t understand the importance of the eyedrops the vet insists I have to hold their eyelids open to administer. They just respond with a variety of noises that I cannot translate. We need to fix this, and thankfully NerdStoke has harnessed Raspberry Pi to build a solution.

How does it work?

The dog wears a harness with a microphone that picks up its barks. The barks get processed through a device that determines what the dog is saying and then outputs it through speakers.

Raspberry Pi Zero is the affordable brain powering NerdStoke’s solution to this age-old human-and-pup problem. But writing code that could translate the multitude of frequencies coming out of a dog’s mouth when it barks was a trickier problem. NerdStoke tried to work it through on Twitch with fellow hobbyists, but alas, the original dream had to be modified.

Spoiler alert: fast Fourier transforms did not work. You would need a clear, pure tone for that to work in a project like this, but as we said above, dogs bark in a rainbow of tones, pitches, and all the rest.

So what’s the solution?

Because of this, a time-based model was devised to predict what a dog is likely to be barking about at any given time of day. For example, if it’s early morning, they probably want to go out to pee. But if it’s mid-morning, they’re probably letting you know the postman has arrived and is trying to challenge your territory by pushing thin paper squares through the flap in your front door. It’s a dangerous world out there, and dogs just want to protect us.

Nerdstoke had his good friend record some appropriate soundbites to go with each bark, depending on what time of day it happened. And now, Nugget the dog can tell you “I want to cuddle” or “Why aren’t you feeding me?”

While the final project couldn’t quite translate the actual thoughts of a dog, we love the humour behind this halfway solution. And we reckon the product name, Holler Collar, would definitely sell.
