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 method and system for recognizing and prompting baby crying, comprising the steps of: acquiring baby crying signals and action images in real time; preprocessing the baby crying signals, calculating and obtaining the reverse Mel of the baby crying signals Frequency cepstral coefficient, and the reverse Mel frequency cepstral coefficient is discretized, and the discrete value of the reverse Mel frequency cepstral coefficient is obtained; the baby cry recognition model established based on the preset Bayesian classification algorithm , classify the discrete values ​​of the inverse Mel frequency cepstrum coefficient, thereby identifying the crying state corresponding to the baby crying signal; use the real-time acquired baby action image to verify the cry obtained from the baby crying signal recognition sound state; send out the corresponding prompt signal. The invention has simple calculation method, high calculation efficiency and high recognition precision, can improve the accuracy and precision of crying state recognition, and can be widely used in the field of baby care.

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...
