Abstract: This application provides a voice interaction method and apparatus. A first apparatus obtains, by using a voice sensor, first voice information including a voice instruction of a user. The first apparatus may determine, based on the first voice information, to perform a target operation indicated by the first voice information. The first apparatus may also send the first voice information to a second apparatus. The first apparatus may determine, based on a first preset condition, to perform a first operation determined by the first apparatus based on the first voice information. The first apparatus may alternatively determine, based on a first preset condition, to perform a second operation indicated by the second apparatus. The solution provided in this application helps balance accuracy and efficiency of voice recognition, and further helps enable the apparatus to appropriately and quickly respond to the user.

Abstract: Example vehicle unlocking methods and apparatus are described. In one example method, wakeup keyword detection is performed on an obtained voice signal. If the voice signal includes a wakeup keyword, an acoustic source direction is determined, and a target camera is indicated to collect image data. The target camera is a target camera that is installed on the vehicle and whose angle of view can ensure that the acoustic source direction is captured. Then, the vehicle is unlocked based on the image data collected by the target camera.
