This idea is awesome!
Analysis of emotions from baby's crying voice "Papatto Parenting @ Baby Notebook" begins offering
It seems to be equipped with a feature that can analyze baby's cries into patterns and analyze why the baby is crying with a smartphone application. The following is a quote from the press release that was posted on PRTimes.
About the crying voice diagnosis function
First Ascent, Inc. has built a crying voice diagnosis algorithm by collecting and analyzing crying voices from over 20,000 monitor users. Users can start the crying voice diagnosis function from the application, and by holding the microphone over a crying baby, they can learn the reason for the crying. The diagnosis algorithm displays the classification and probability of the five categories analyzed as highly likely: "hungry," "sleepy," "uncomfortable," "angry," and "want to play. According to the results of feedback from monitor users in advance, the correct answer rate of more than 80% has been recorded.
By increasing the number of users and collecting more sampling cries, they aim to improve the accuracy of cries diagnosis by machine learning.
One question I have is what is used to determine the percentage of correct answers. Well, does it mean that the baby has stopped crying = the baby has understood the appeal? I think the difference between discomfort and anger is also a very fine line. For example, if your body is hot and uncomfortable, and you're hot and angry, it's hard to say whether you're uncomfortable or angry. Still, it's better than no information, and if we can provide accurate information, it will greatly help a third party to watch over the baby. I have high hopes for the future.
