Abstract: Embodiments of the present disclosure are directed to a speech interaction method executed at an electronic device, a speech interaction apparatus, and a computer readable storage medium. The method includes receiving an image sequence of a user from an image capturing apparatus coupled to the electronic device. The method also includes detecting a change in a head feature of the user from the image sequence. After that, the method includes determining whether the change in the head feature matches a predetermined change pattern. The method further includes causing the electronic device to enter an active state in response to determining that the change in the head feature matches the predetermined change pattern, the electronic device in the active state being capable of responding to a speech command of the user.
