Embodiment Construction

[0045] refer to figure 1 , the present invention provides a kind of baby cry recognition prompting method, comprises the following steps:

[0046] Obtain the baby's crying signal and action image in real time;

[0047] After preprocessing the baby crying signal, calculate the reverse Mel frequency cepstrum coefficient of the baby crying signal, and discretize the reverse Mel frequency cepstrum coefficient to obtain the reverse Mel frequency cepstrum coefficient discrete value;

[0048] According to the baby crying recognition model established based on the preset Bayesian classification algorithm, the discrete values ​​of the reverse mel-frequency cepstral coefficient are classified and processed, thereby identifying the crying state corresponding to the baby crying signal;

[0049] Based on the preset action behavior database, the baby action image acquired in real time is used to verify the crying state obtained from the baby crying signal recognition;

[0050] Based on t...

Abstract

The invention discloses a recognition and warning method and system for crying sounds of infants. The method comprises: acquiring a crying sound signal and a motion image of an infant in real time; carrying out pretreatment on the crying sound signal of the infant, carrying out calculation to obtain an inverted Mel-frequency cepstral coefficient of the crying sound signal of the infant, carrying out discretization on the inverted Mel-frequency cepstral coefficient to obtain a discrete value of the inverted Mel-frequency cepstral coefficient; according to a preset infant crying sound identification model established based on a Bayesian classification algorithm, classifying the discrete value of the inverted Mel-frequency cepstral coefficient to identify a crying sound state corresponding tothe crying sound signal of the infant; checking the crying sound state obtained by identification of the crying sound signal of the infant by using an infant motion image obtained in real time; and sending out a corresponding warning signal. According to the invention, the calculation method is simple; the calculation efficiency is high; the recognition accuracy is high; and the accuracy and precision of crying sound state recognition are improved. The recognition and warning method and system can be widely applied in the baby care field.

Description

technical field [0001] The invention relates to the technical field of baby sound analysis, in particular to a method and system for recognizing and prompting baby crying sounds. Background technique [0002] Crying is the only way for babies to express, and it is a special "language". There are several basic expressions of baby crying, including hunger, sleepiness, need to burp, intestinal cramps and discomfort. There is an inherent typical pattern, but adults generally cannot accurately understand the reasons for babies to cry, and cannot understand the needs of babies' crying, which will inevitably lead to inadequate care and care for babies, which is not conducive to the healthy growth of babies. For the current medical service institutions such as neonatology, obstetrics, or confinement centers, during the baby's hospitalization, the monitoring of the baby's crying is to manually check the baby's condition after collecting the baby's crying sound, or to collect the bab...
