Baby crying reason distinguishing method and device, terminal and storage medium

The invention provides a baby crying reason distinguishing method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a baby crying audio signal; extracting time domain features of the baby crying audio signal, and determining crying duration and crying interruption times of the baby crying audio signal based on the time domain features; fourier transform is carried out on the baby crying audio signal to obtain a frequency spectrum of the baby crying audio signal, frequency spectrum features are extracted from the frequency spectrum, and the frequency spectrum features comprise formant information and energy entropy information; and determining a baby crying reason corresponding to the baby crying audio signal based on the crying duration, the crying interruption times and the spectrum characteristics. According to the method, the acoustic characteristics of baby crying are carefully researched, and the characteristics with high discrimination are found out to iden
