Recently, an unusual album stormed the Australian charts.
Now, an international research team has been focusing their attention on a species which, according to DNA comparisons, is remarkably similar to our own.
The team analysed the sounds of pigs in happy and stressful situations, with recordings made from birth to death.
Positive feelings were expressed by a short grunt; negative emotions by a longer squeal.
An AI trained using more than 7,000 pig recordings was 92% accurate in its interpretation of emotions and even able to decode more nuances than the team.
A monitoring app based on these results would significantly improve animal welfare in breeding farms.
This alternative and new ways to grow vegetables also sound good.
