Voice wake-up method, device, storage medium and system

The invention relates to the technical field of terminals, in particular to a voice wake-up method and device, a storage medium and a system. The method comprises the following steps: acquiring original first microphone data; performing first-stage processing according to the first microphone data to obtain first wake-up data, wherein the first-stage processing comprises first-stage separation processing and first-stage wake-up processing based on a neural network model; when the first wake-up data indicates successful pre-wake-up, performing second-stage processing according to the first microphone data to obtain second wake-up data, wherein the second-stage processing comprises second-stage separation processing and second-stage wake-up processing based on a neural network model; and determining a wake-up result according to the second wake-up data. According to the embodiment of the invention, by designing the two-stage separation and wake-up scheme, the pre-wake-up judgment is carried out through the firs
