A teen, an algorithm and the race to stop poaching

8:48Richard HedleyGUEST
We ended up throwing out a lot of the data and only looked at the loudest gunshots in the recording.

8:55Daniela HedwigGUEST
Our problem is that we do have detection algorithms, and we can make them so that they find the gunshots, but that comes at a cost.
D
9:04Daniela HedwigGUEST
And that cost is that we're detecting thousands and thousands of other signals that are not gunshots.
D
9:11Daniela HedwigGUEST
That means that we need a person to actually look and listen to all the detections and make the final decision, and this is where acoustic monitoring and its potential really reaches a bottleneck.

Melissa HobsonCORRESPONDENT
It's important to acknowledge that there are many social and economic issues that contribute to poaching.
D
11:33Daniela HedwigGUEST
It's a very complex problem, you know, where poaching needs to be tackled from multiple angles.
D
11:40Daniela HedwigGUEST
In this context, we often talk about poachers, and we paint them so negatively, but I would like to say that the vast majority of people that are going in a national park to hunt are just, you know, people that are trying to make ends meet.
D
11:56Daniela HedwigGUEST
We're talking about people here that often don't have much, and they are trying to feed their children.
