A new app decodes babies’ crying after only 10 seconds of recording.
The revolutionary app has been developed by a team of researchers from the Taiwan National University Hospital Yunlin.
The Infant Cries Translator can differentiate among four different cryings by comparing the recordings with an extended database.
The Taiwaneese researcher collected about 200,000 crying sounds of about 100 babies over a period of two years. They then uploaded the sounds to an online database. The team of researchers led by Dr. Chen Si-da and Chang Chuan-yu has analyzed the frequency of individual screams and have finally became able to distinguish subtle acoustical differences between them.
The app is 92 percent accurate in distinguishing the crying sound of newborn babies under two weeks old and becomes less accurate as the child grows older. The new app needs only 15 seconds to tell parents if their newborn has a wet diaper or if they are in pain or sleepy or hungry.
However the app can still be used for older babies, keeping about 85 percent of its accuracy for babies under one or two months old and up to about 77 percent for babies younger than four months.
According to its developers, the app becomes totally useless once the child becomes older than six months as the baby starts being affected by many other different factors from their environment besides their primary needs that are hunger, sleep, pain and wet diaper.
However many parents could find the app very helpful, especially if they are having their first children. They can even set up a personal screaming translator for their baby since the app is constantly updating its database to a Cloud Drive.
Chang explains that once the app is downloaded parents only need to set the date of birth and the newborn’s nationality. When the baby is crying the parents need to record ten seconds of the screaming and then the sound will be automatically uploaded to the Cloud. After analyzing its specificities and comparing the sounds with others from the database the app returns the result to the parent’s smartphone.
Parents can rate the accuracy of the result and make revisions. By doing so they improve the app which might give a better response in the future.
The Infant Cries Translator can be downloaded from Google Play and App Store at a price of only $2.99 USD.
