Abstract

The invention discloses an emotion detection method and device based on baby cry and relates to the technical field of big data. The emotion detection method comprises the following steps: acquiring ato-be-detected baby cry signal, and windowing the baby cry signal. The baby cry window signals in each time window are respectively subjected to fast Fourier transform so as to generate a spectrogramcorresponding to the baby cry signal. The spectrogram is input into a well-trained emotion detection model so as to determine the emotion corresponding to the baby cry signal. Therefore, the baby crysignal is converted into a corresponding sound frequency spectrum image through Fourier transform, and a capsule network is used for carrying out emotion recognition on the sound frequency spectrum,thereby improving the recognition accuracy of the baby cry. According to the technical scheme provided by the embodiment of the invention, the problem of low recognition accuracy of the baby cry in the prior art can be solved.

Description

【Technical field】 [0001] The present invention relates to the field of big data technology, in particular to an emotion detection method and device based on baby crying. 【Background technique】 [0002] In the related art, the voice signal is directly input into the voice recognition model, and the corresponding emotion recognition result is output, so as to realize the emotion recognition of the voice signal. Among them, the voice recognition model is a pre-trained neural network. [0003] For a specific type of sound signal such as baby crying, there is no specific speech content, and the existing sound recognition model has the problem of low recognition accuracy. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides an emotion detection method and device based on a baby's cry to solve the problem of low accuracy of emotion recognition of a baby's cry in the prior art. [0005] On the one hand, an embodiment of the present inv...
