I mean it could be, she could have a wet diaper. She could be hungry. She could be tired. She could be bored. Scott Williamson lists the many reasons why his five-month-old daughter Julie could be crying. Like all new parents, he quickly learned that a baby can be upset about a number of things, but figuring out exactly why is not always easy. It’s always a checklist, you try your best. I think it’s this, I think it’s that. But the frustrating guessing game may finally be over.UCLA neuropsychologist and mother of four, Dr. Arianna Anderson, has developed an app that helps parents decipher their baby’s cries. When I had my third baby, I realized that her cries were a lot very similar to the other two children, and I could recognize what she needed based on how her cry sounded. The app is easy to use: A parent holds the phone near the crying baby and waits as the app listens and comes up with a possible explanation. For now, the program offers just three reasons for why a baby is crying, hunger, fussiness and pain. 我觉得可能有很多原因吧：她可能是尿布太湿了，可能是不高兴了，可能是累了，可能是厌倦了。斯科特(Scott Williamson)想了很多原因，猜测自己5个月大的女儿朱莉为何会哭。跟很多新上任的奶爸奶妈一样，斯科特很快就了解到：婴儿可能因为很多事情而感到焦虑，但要确定原因是哪个并不容易。基本上就是一个排除列表的过程，尽力去猜吧：一会觉得是这个，一会觉得是那个。但这个让人沮丧的猜猜猜游戏可能终于要结束了。 加州大学洛杉矶分校的神经心理学家阿里安娜 安德森(Arianna Anderson)是4个孩子的妈妈，她研发了一款应用程序。这款程序可以帮助奶爸奶妈们解读婴儿的哭声。我生了第3个孩子之后，我就发现，她的哭声跟另外两个孩子特别像。所以，我可以根据她的哭声来判断她想要什么。这款程序很容易上手：奶爸奶妈只需要将手机放在啼哭的婴儿附近，让手机听完孩子的哭声，然后等待一个最有可能的解释。目前，这款程序只能提供3类啼哭的原因：饥饿、愤怒、疼痛。
