Dogs are essential companions for many homes

Normally, after living with dogs, it is easy to know what they want by quickly identifying their barking. It is not the same when they are playing as when they try to mark territory in front of other animals or humans, for example. Not everyone has had a dog and therefore does not have to understand their “verbal” or body language, in fact there are many applications that serve to differentiate dog breeds or even to educate them in a more appropriate way. For this reason, a team has developed a technology through AI to find out what the barking of these animals means and the truth is that they have achieved it in a rather curious way.

To better understand dogs, but also the world around us

An article available for prepress in Arxiv.org has unveiled a truly amazing new technology. A team of researchers have been able to decode the meaning of dog barking. To do this, they have used the processing power of the AI and a corpus of very complete recordings with barks, growls and howls of 74 totally different domestic dogs in different situations to observe how they responded to each stimulus.

Interestingly, they have used the Wav2Vec2 AI model that was actually aimed at human people and voice recognition. However, they have been able to extrapolate it without problems to the sound of dogs. This is more interesting than it seems: does the human voice have any parallels with other modes of mammalian communication? It is obvious that it is, since it has been perfectly extrapolated indicating a certain inevitable union between very similar species.

From this point on, they were able to observe up to 14 different subtypes of dog noise. They divided them into three: positive, sadness and anxiety and finally aggressive barking. In this way, they were able to synthesize the needs that a dog showed depending on the noise they made and manage to understand their needs in a much more accessible way. Although, all dog owners know, after some time living together, what every noise emitted by the animal refers to, even the most subtle ones. However, inexperienced people can lead these signals to a mistake that can be tense for both the animal and the person.

The AI has been able to correctly interpret 62.2% of the cases, although there were notable differences between the different dog breeds. Those that emitted louder sounds were easier to decipher, while those with lower registers made it almost impossible for the machine. In this way, although there is much to know in this field, it is clear that it can be a very important leap forward in everything we know about animal communication.

Above all, it is incredibly useful when it comes to taking applied research on humans and being able to take it to other fields of biology that have little to do with our species. Thus representing a really interesting leap forward for the future of any research or development that wants to be carried out in this regard.
