Babies don't come with a manual, but a new app ishelping to take some of the guesswork out of theircries.
The app is the brainchild of a doctor at the UCLAalong with a team of volunteers.
Known as ChatterBaby, the free app was initiallycreated to help deaf parents figure out what theirchild needs.
But even people with full hearing have trouble differentiating between whether junior's hungry, fussy or in pain.
The team developed an algorithm that identified the characteristics of each type of cry, likechanges in pitch, frequency, pauses. Using this information, the algorithms nearly correctlyidentified features of cries.
The creator hopes this app will also help users identify autism in their children earlier.
