Methods and apparatuses for recognizing a two-dimensional code are disclosed. In an implementation, a method comprises: identifying, by an electronic device, a two-dimensional code, wherein the two-dimensional code comprises an image region in the center and a ring region surrounding the image region, wherein the ring region comprises a code region including a first code region and a second code region, a first spacing region, and a second spacing region, wherein the first spacing region and the second spacing region are arranged between the first code region and the second code region, determining values corresponding to a plurality of code elements in the code region, and recognizing, by the electronic device based on the values, first information corresponding to the two-dimensional code.

Method for recognizing two-dimensional code and related apparatus

Embodiments provide a voice interaction method and an apparatus, and relate to the field of terminal technologies. Common voice skill commands in a first application scenario may be determined based on the first application scenario and a historical voice skill usage record, and displayed in a display interface. This can implement scenario-based recommendation of voice skill commands, to cover as many application scenarios as possible. In this application, after being woken up, the voice assistant determines the first application scenario based on one or more information items. The voice assistant determines the common voice skill commands in the first application scenario based on the first application scenario and the historical voice skill usage record. The voice assistant displays the common voice skill commands in the first application scenario in the display interface.
