Problems solved by technology

[0004] However, the inventors of the present invention have found that the current technical solutions can only give a reason for crying (select a display from a plurality of reasons for crying, or judge whether it belongs to a specific reason for crying), and this method is used in actual use. The reason for crying is often far less accurate than claimed, and inexperienced young mothers often try to solve the reason and the baby continues to cry, which makes them more flustered

[0072] Time-frequency characteristics: After the audio signal undergoes time-frequency analysis, various shapes and parameters in the time-frequency plane. Time-frequency analysis can include various analysis algorithms such as Fourier transform.

[0073] It should be particularly noted that the various reasons for crying in the present invention refer to possibilities. In particular, the "pathological" reasons for crying do not refer to confirmed illnesses, let alone certain diseases, but only indicate illnesses. It is more likely. It is recommended to go to the hospital fo...

Abstract

The invention, which relates to the infant nursing field, discloses an automatic identification method and system for an infant crying cause. With the method and system, young parents lack of parenting experience can find out crying causes of infants accurately. The method comprises: a baby crying sound is recorded and a crying audio signal is obtained; a time-frequency characteristic is extracted from the crying audio signal, and probabilities, corresponding to preset different crying causes, of the time-frequency characteristic are obtained according to the time-frequency characteristic and a classified obtained by training in advance; and at least two kinds of crying causes with the highest probabilities and probabilities of the crying causes are displayed at a terminal screen.

Description

Technical field [0001] The present invention relates to the field of infant care, and particularly relates to an automatic identification technology of the reason for infant crying. Background technique [0002] Crying is the baby's first way to pronounce it, and it is also the only way for a baby to communicate with the outside world. Experienced mothers and doctors can understand the baby's mood, needs and health through the baby's cry. Due to the declining birth rate in modern society, many mothers have only one child and lack relevant experience. They urgently need technical means to help young mothers understand the needs of their babies through crying. [0003] With the development of computer technology and communication technology, some related technical solutions have emerged. For example, the entered baby crying is converted into a computer-readable format, and the cause of crying can be identified by filtering the digital signal, estimating the basic frequency, lubrica...
