An app developed in Taiwan is helping parents answer their babies' needs more accurately. The Infant Cries Translator app records a baby's cries and compares them to a database of 200,000 other crying sounds, according to USA Today. 

Researchers at the National Taiwan University Hospital who monitored the sounds of 100 newborns over a two-year period developed the app, which is able to distinguish between four different crying sounds, and Reuters reports it can tell if a baby is hungry, sleeping in pain or has a wet diaper.

"So far, according to the feedback from users, the accuracy of the app we've tested can reach 92 percent for babies under two weeks old. As for the babies under one or two months, the accuracy of the app can also reach up to 84 or 85 percent. Even for the four month old baby, the accuracy can reach 77 percent," lead researcher Chang Chuan-yu explained. The app responds in about 15 seconds, according to the Daily Mail.

Plus, the app is constantly updated. If the app is incorrect, parents can simply send back information to the researchers who can then update the online database.

You can download the Infant Cries Translator on your Android or iPhone smartphones.
