Abstract
A method for voice wakeup is provided, which includes: obtaining original first microphone data; performing first-stage processing based on the first microphone data to obtain first wakeup data, wherein the first-stage processing includes first-stage separation processing and first-stage wakeup processing that are based on a neural network model; performing second-stage processing based on the first microphone data to obtain second wakeup data when the first wakeup data indicates that pre-wakeup succeeds, wherein the second-stage processing includes second-stage separation processing and second-stage wakeup processing that are based on the neural network model; and determining a wakeup result based on the second wakeup data. According to this application, a two-stage separation and wakeup solution is designed, e.g., pre-wakeup determining is performed by using a first-stage separation and wakeup solution, and wakeup determining is performed again after pre-wakeup succeeds, to reduce a false wakeup rate while ensuring a high wakeup rate.
