Babies don't come with a manual, but a new app is helping to take some of the guesswork out of their cries.

婴儿啼哭的原因令人费解，不过一款名为ChatterBaby的新应用可帮助人们从其哭泣中获得某些信息。

The app is the brainchild of a doctor at the UCLA along with a team of volunteers.

该应用是加州大学洛杉矶分校一位博士和一组志愿者智慧的结晶。

Known as ChatterBaby, the free app was initially created to help deaf parents figure out what their child needs.

他们最初设计这款免费应用是想帮助失聪父母了解孩子的需求。

But even people with full hearing have trouble differentiating between whether junior's hungry, fussy or in pain.

不过就算是听力正常的人也很难区分婴儿到底是饥饿、不满还是痛苦。

The team developed an algorithm that identified the characteristics of each type of cry, like changes in pitch, frequency, pauses. Using this information, the algorithms nearly correctly identified features of cries.

该研究小组研发出一种算法，可以识别出每种哭声的特征，如音高、频率、停顿等方面的变化。通过这些信息，算法基本能准确地分辨婴儿啼哭的特征。

The creator hopes this app will also help users identify autism in their children earlier.

开发者希望此应用也能够帮助用户更早地辨别出孩子是否患有自闭症。
