Computer learns dogspeak
Date:1/16/2008

The aim of Molnr and colleagues experiments was to test a computer algorithms ability to identify and differentiate the acoustic features of dog barks, and classify them according to different contexts and individual dogs. The software analyzed more than 6000 barks from 14 Hungarian sheepdogs (Mudi breed) in six different situations: stranger, fight, walk, alone, ball and play. The barks were recorded with a tape recorder before being transferred to the computer, where they were digitalized and individual bark sounds were coded, classified and evaluated.

In the first experiment looking at classification of barks into different situations, the software correctly classified the barks in 43 percent of cases. The best recognition rates were achieved for fight and stranger contexts, and the poorest rate was achieved when categorizing play barks. These findings suggest that the different motivational states of dogs in aggressive, friendly or submissive contexts may result in acoustically different barks.

In the second experiment looking at the recognition of individual dogs, the algorithm correctly classified the barks in 52 percent of cases. The software could reliably discriminate among individual dogs while humans can not, which suggests that there are individual differences in barks of dogs even though humans are not able to recognise them.

The authors conclude by highlighting the value of their new methodology: The use of advanced machine learning algorithms to classify and analyze animal sounds opens new perspectives for the understanding of animal communicationThe promising results obtained strongly suggest that advanced machine learning approaches deserve to be considered as a new relevant tool for ethology*.
