Abstract: A voice interaction method includes: after detecting a voice interaction initiating indication, a terminal enters a voice interaction working state; the terminal receives first voice information, and outputs a processing result for the first voice information; the terminal receives second voice information, and determines whether a sender of the second voice information and a sender of the first voice information are a same user; and if determining that the senders are the same user, the terminal outputs a processing result in response to the second voice information, or if determining that the senders are different users, the terminal ends the voice interaction working state.

Abstract: A voice user interface display method and a conference terminal are provided. The method includes: when voice information input by a user into the conference terminal is received, a voice of the user is collected. A user voice instruction may be obtained based on the voice information input by the user. Identity information of the user may be obtained in real time based on the voice of the user. Further, user interface information that matches the user may be displayed based on the identity information of the user, the user voice instruction, and a current conference status of the conference terminal. The method improves diversity of display of the user interface information and improves user experience in using the conference system.
