determining, in response to receiving reply information inputted by the first user, whether an answer matching the reply information is included in a predetermined answer set, the answer corresponding to the user identity information; and determining, if the answer is included in the predetermined answer set, the user identity information corresponding to the answer matching the reply information as the identity information of the first user. ### Claim 5 (depends on 3) The method according to claim 3, wherein the generating a first voiceprint characteristic vector based on the first voice comprises: importing the first voice into a pre-trained universal background model to perform mapping to obtain a first voiceprint characteristic super-vector, the universal background model being used to represent a corresponding relationship between voice and the voiceprint characteristic super-vector; and performing a dimension reduction on the first voiceprint characteristic super-vector to obtain the first voiceprint characteristic vector. ### Claim 6 (depends on 1) The method according to claim 1, further comprising: recording, in response to determining the first user belonging to a predetermined population group according to the identity information of the first user, a time point of determining the identity information of the first user as a viewing start time of the first user; and outputting time prompting information or performing a turnoff operation, in response to determining at least one of a difference between a current time and the viewing start time of the first user being greater than a viewing duration threshold of the predetermined population group or the current time being within a predetermined time interval. ### Claim 7 (depends on 1) The method according to claim 1, wherein the identity information comprises at least one of: gender, age or family member identifier. ### Claim 8 (depends on 7) The method according to claim 7, further comprising: in response to receiving second voice of a second user, generating a second voiceprint characteristic vector based on the second voice; inputting the second voiceprint characteristic vector into a voiceprint recognition model to obtain identity information of the second user, the recognition model being used to represent a corresponding relationship between the voiceprint characteristic vector and the identity information of the user; and determining a younger user from the first user and the second user, and selecting an operation option page matching a user mode corresponding to the younger user from the preset operation option page set to output the operation option page. ### Claim 9 An apparatus for outputting information, comprising: at least one processor; and a memory storing instructions, wherein the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising: receiving a message of requesting to enter a target user mode, the message being inputted by a first user;
