AI can distinguish the meaning of the baby's cry by AI

The baby's crying makes parents worry and annoy. Research is being conducted to distinguish between 'normal crying' and 'abnormal crying' by listening to such baby's crying using artificial intelligence (AI).

Your baby will cry when he is hungry or sick and sick, but he may also cry to attract the attention of his parents. It has been thought that it would be possible to recognize the meaning of the cry exactly as a skilled parent or expert can understand the meaning of the cry of the baby to some extent.
Therefore, we analyzed the 'voice characteristics in the frequency domain' of the cry of an infant with various meanings and tried to recognize 'the reason why the baby is crying' by the associate professor at the Department of Electrical Engineering of Northern Illinois University. A research team headed by Lichuan Liu who works as

The research team uses the linear prediction code to extract sound features from infant crying in the form of Linear Predictive Cepstrum Coefficient (LPCC), Bark Frequency Cepstrum Coefficient (BFCC), Mel Frequency Cepstrum Coefficient (MFCC).
Furthermore, using a method called compressed sensing , it seems to have processed a large amount of extracted data efficiently. If audio data is recorded in a noisy environment, necessary and unnecessary elements are mixed and processing becomes difficult, but compressed sensing is a process of reconstructing a signal based on sparse data. Because of that, it seems to be useful for processing noisy audio data.
By processing these data, the development team succeeded in developing a new algorithm based on an automatic speech recognition function that can detect and recognize infant crying. This algorithm seems to be able to distinguish between the 'normal cry' and the 'abnormal cry' of the infant, and is not specialized for recognizing the cry of one infant, but the universality of the infant's cry It has become possible to read the meaning.

As the algorithm can be used as a way to better understand why the baby is crying and how urgent the crying is, developer Liu said, 'Various things like a special language. There is a lot of health related information in the cry, and the difference in the sound signal carries the information.These differences are expressed by the difference in the features of the cry, and the information is recognized and used In order to do this, it is necessary to extract features and obtain the necessary information in it.
