Scientists decode pig language and now want to create a translator

The possibility of a real pig language translator is getting closer after the results of a new study have revealed how pigs’ growls and squeals translate into their emotions.

Lead researcher Elodie Briefer from the University of Copenhagen said in a press release on March 7, 2022 that she had trained an algorithm to decode pig sounds. They are now looking for a developer to use the algorithm in an app so farmers can monitor the welfare of their pigs.

The researchers collected 7,414 audio recordings from 411 pigs from birth to death. Audio recordings were made as the pigs engaged in 19 different activities in commercial and experimental settings. Using their data, the researchers studied how vocal parameters such as the duration and amplification of a sound changed depending on a pig’s emotion.

The researchers found that the duration of sounds is shorter in both low- and high-frequency calls when pigs engage in positive experiences compared to negative experiences. It was the same in terms of amplifying a sound. Pig amplified his sounds less in low and high frequency calls during positive experiences.

To put their findings into practice, the researchers wanted to create a sound detection system that could classify pig sounds in real time.

The researchers used an image classification neural network with the spectrograms of the audio recordings. This algorithm was trained to determine whether a sound was produced during a positive or negative experience and in which activity a sound was produced.

Using this algorithm, the researchers were able to accurately classify sounds whether they relate to positive or negative emotions by 91.5% The algorithm was also able to accurately classify the context in which the sound was 81.5% proceeds
