Babies don't come with a manual, but a new app is helping¹ to take some of the guesswork out of their cries.

But even people with full hearing have trouble differentiating³ between whether junior's hungry, fussy⁴ or in pain.

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.
