A recently unveiled Taiwanese app can help new moms understand their babies’ cries, and clearly differentiate between four basic crying sounds, or at least this is what the developers said.
Researchers at the National Taiwan University Hospital Yunlin claim that their app can accurately tell whether the baby cries because he or she is hungry, in pain, has a wet diaper, or needs to go to sleep. The Infant Cries Translator records the infant crying and compares the input against an online collection of 200,000 infant cry samples.
It took about two years for the app to be ready, and about 100 newborns were involved in the process. Chang Chuan-yu, one of the developers, explained that there are differences in both the pitch and frequency of babies’ cries which can provide valuable clues on what the infants try to communicate.
The app needs about 15 seconds to ‘translate’ the baby crying sound. Parents will understand what their offspring is ‘saying’ with a 92 percent accuracy, the team claims. Still, infants should be no older than 2 weeks old for the best results. As the child grows, other factors influence their crying making the app less accurate.
A separate analysis showed that in children between 2 weeks and 2 months old the accuracy drops to about 85 percent. In four months olds, the app can translate the crying sounds with 77 percent accuracy. From the age of six months, parents should no longer rely on the app, as it now has a high error margin.
Beyond that age, the baby cries because of some factors external to him or her. Nevertheless, scientists hope that the app could help new moms and dads to rear their firstborns.
The team explained that the online database is constantly updated with new sounds. This is why, parents can instruct the app to filter their baby’s crying sounds and create a personal setting based on parental feedback.
Developers said that the app is intuitive and doesn’t require too much effort to be used. After installation, parents would need only to insert their baby’s birth date and nationality. Afterwards, they can tap on the recording button and let the smartphone grab the crying sound for at least 10 seconds.
All crying sounds are first stored in the cloud. Next, a computer algorithm will analyze them and beam results to parents’ phones. If parents feel that the analysis is inaccurate they can provide feedback for the app to be improved.
