Abstract: This application provides a voice interaction processing method and apparatus, to achieve a friendly and natural voice interaction effect and reduce power consumption. In the method, a microprocessor enables an image collector only when determining, based on voice data collected by a voice collector, that a first user is a target user; then the image collector collects user image data and transmits the user image data to the microprocessor; and the microprocessor sends a wakeup instruction to an application processor only when determining, based on the user image data, that the target user is in a voice interaction state. Based on the foregoing method, nus-enabling of the image collector and the application processor is avoided to some extent, and power consumption is reduced.
