研究表明，猪的叫声透露了它们的情绪

A database of thousands of grunts, oinks, snuffles and squeals, gathered and recorded from hundreds of pigs at every stage of their lives, will be used to help farmers better understand their animals' emotional states and improve their welfare in the future, according to a new study.

一项新的研究表明，收集记录几百头猪在生命的各个时期的几千组各种叫声，将会用于帮助农民未来更好地理解动物的情绪，提高它们的福祉。

The researchers used an artificial intelligence system that determines with high accuracy whether the vocalizations made by pigs are expressions of positive or negative feelings, and even the circumstances where the sounds are made -- including situations such as nursing piglets, meeting their mothers or littermates, waiting around, being surprised, and huddling together.

研究者使用人工智能系统，精确地判断猪发出的声音表达的是积极还是消极情绪，甚至它们发出声音时所处的环境——包括：比如小猪仔，看到了妈妈或者同窝猪仔、等待、惊讶、挤在一起等。

It turns out that pigs are among the most talkative farm animals, so their vocalizations have often been studied to find out what they're saying.

研究结果表明，猪是话多的动物，所以它们发出的声音被人研究，以发现它们在说什么。

The findings confirmed what was suggested by previous studies -- in general, high-pitched calls correspond to negative emotional states, while low-pitched calls correspond to positive states. But the researchers also observed a large number of calls that weren't easily categorized. For example, some high-pitched calls with short durations that didn't vary much in volume could actually be positive.

这些研究也印证了此前研究的假设：一般来说，高音的叫声对应的是负面情绪，而低音的叫声对应的是积极情绪。但是研究者也发现大量叫声难以归类。比如一些短促的高音，音调不变，可能实际上表达的是积极情绪。

Such a high level of accuracy could be good news for pigs on farms -- the exact number is unknown, but there are estimated to be more than 650 million around the world.

类似精确的研究对养猪场的猪（虽然准确的数量未知，但估计全世界有6.5亿头）来说可能是好消息。

Briefer and her colleagues now intend to implement their pig grunt database in a software application that will monitor the vocalizations made in commercial pig herds and notify farmers when their animals express high levels of negative emotions, such as when piglets cry out that they are being crushed by their mother, a recurrent problem among pigs and one of the contexts that can be distinguished using the database.

Briefer和他的同事计划把他们的猪的叫声数据导入应用软件，这个软件可以检测出商品猪群发出的叫声，当猪表现出高度的负面情绪时，提醒猪农。比如小猪因母猪挤压而嚎叫，这在猪群中经常发生，使用这个数据库可以将这一场景识别出来。

McElligott notes the welfare of pigs in commercial farms is a major concern worldwide. "The numbers are huge," he said. "This tool will allow us to improve the lives of these animals."

McElligott提出，商业猪场的猪的福祉是全世界关注的问题。“数量巨大，”他说，“这个方法可以让我们改善这些动物的生活”。
