sending a current multimedia content playlist to a playing terminal;
analyzing, in response to receiving a voice updating request from a user to update currently played multimedia content in the current multimedia content playlist, the voice updating request to obtain an updating instruction corresponding to the currently played multimedia content;
searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist; and
sending the optimized multimedia playlist to the playing terminal,
wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
determining that the updating instruction comprises a media name of the currently played multimedia content, an identifier for a leading author, and an instruction for switching a performer, wherein the leading author comprises the performer; and
in response to determining that the updating instruction comprises the media name of the currently played multimedia content and the instruction for switching the performer, generating the optimized multimedia playlist by searching the preset multimedia content database for multimedia content with the media name and without a name of the performer, the optimized multimedia playlist including the multimedia content with the media name found from the preset multimedia content database and excluding the multimedia content with the name of the performer, and

wherein the method is performed by at least one processor.

2. The method according to claim 1 , wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
determining that the updating instruction comprises an instruction for switching the currently played multimedia content; and
in response to determining that the updating instruction comprises the media name of the currently played multimedia content and the instruction for switching the currently played multimedia content, generating the optimized multimedia playlist by searching the preset multimedia content database for multimedia content with the media name and other than the currently played multimedia content, the optimized multimedia playlist including the multimedia content with the media name found from the preset multimedia content database and excluding the currently played multimedia content.

3. The method according to claim 2 , wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
determining that the updating instruction comprises a keyword belonging to a preset category; and
in response to determining that the updating instruction comprises the identifier for the leading author and the keyword belonging to the preset category, searching the preset multimedia content database with the identifier for the leading author and the keyword indicated by the updating instruction as a search condition to generate the optimized multimedia playlist;
wherein the preset multimedia content database has a search index pre-established on a basis of the keyword.

4. The method according to claim 3 , wherein the updating instruction comprises a plurality of keywords belonging to the preset category; and
the searching in the preset multimedia content database with the identifier for the leading author and the keyword indicated by the updating instruction as a search condition to generate the optimized multimedia playlist comprises:
in response to determining that multimedia content satisfying both the identifier for the leading author and all keywords contained in the updating instruction is not found from the preset multimedia content database, selecting a portion of keywords from the all keywords contained in the updating instruction, and searching the preset multimedia content database with the identifier for the leading author and the selected keywords indicated by the updating instruction as the search condition to generate the optimized multimedia playlist.

5. The method according to claim 1 , wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
determining whether the updating instruction comprises similar search intention; and
in response to determining that the updating instruction comprises similar search intention, searching the preset multimedia content database for multimedia content having a similarity to the currently played multimedia content greater than a preset similarity threshold to generate the optimized multimedia playlist.

6. The method according to claim 5 , further comprising:
in response to determining that the updating instruction comprises the similar search intention, determining whether the updating instruction comprises a keyword having a preset category; and
in response to determining that the updating instruction comprises the keyword including having the preset category, searching the preset multimedia content database for multimedia content having a similarity to the currently played multimedia greater than the preset similarity threshold and satisfying a search condition indicated by the keyword comprised in the updating instruction to generate the optimized multimedia playlist;
wherein the preset multimedia content database has a search index pre-established on a basis of the keyword.

7. An apparatus for updating a multimedia playlist, the apparatus comprising:
at least one processor; and
a memory storing instructions, which when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
sending a current multimedia content playlist to a playing terminal;
analyzing, in response to receiving a voice updating request from a user to update currently played multimedia content in the current multimedia content playlist, the voice updating request to obtain an updating instruction corresponding to the currently played multimedia content;
searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist; and
sending the optimized multimedia playlist to the playing terminal,
wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
determining that the updating instruction comprises a media name of the currently played multimedia content, an identifier for a leading author, and an instruction for switching a performer, wherein the leading author comprises the performer; and
in response to determining that the updating instruction comprises the media name of the currently played multimedia content and the instruction for switching the performer, generating the optimized multimedia playlist by searching the preset multimedia content database for multimedia content with the media name and without a name of the performer, the optimized multimedia playlist including the multimedia content with the media name found from the preset multimedia content database and excluding the multimedia content with the name of the performer.

8. The apparatus according to claim 7 , wherein the searching in a preset multimedia content database based on the updating instruction to generate an optimized multimedia playlist comprises:
