selecting, based on the first keyword set and the subcategory set, a song list from a pre-generated song list set as a to-be-played song list, to generate a to-be-played song list set, the song list including at least one piece of audio and song list category information, wherein the first category keyword is preset to have a weight value, and the selecting, based on the first keyword set and the subcategory set, a song list from a pre-generated song list set as a to-be-played song list, to generate a to-be-played song list set comprises:
determining, in response to at least two first keywords being included in the first keyword set, whether a song list satisfying a preset condition is included in the pre-generated song list set, based on the at least two first keywords and subcategories to which the at least two first keywords belong;
selecting, in response to the song list satisfying the preset condition being included in the pre-generated song list set, the song list satisfying the preset condition as the to-be-played song list, to generate the to-be-played song list set;
determining, in response to the song list satisfying the preset condition being not included in the pre-generated song list set, weight values of the at least two first keywords respectively; and
selecting, based on the first keyword having the maximum weight value and a subcategory to which the first keyword having the maximum weight value belongs, a song list from the pre-generated song list set as the to-be-played song list, to generate the to-be-played song list set.

2. The method according to claim 1 , further comprising:
determining, in response to determining a preset second category keyword being included in the first user sentence, the second category keyword included in the first user sentence as a second keyword; and
determining, based on the second keyword and the first keyword set, a target keyword from the first category keyword, and determining a subcategory to which the target keyword belongs,
wherein the selecting, based on the first keyword set and the subcategory set, a song list from a pre-generated song list set as a to-be-played song list, to generate a to-be-played song list set comprises:
selecting, based on the target keyword and the subcategory to which the target keyword belongs, a song list from the pre-generated song list set as the to-be-played song list, to generate the to-be-played song list set.

3. The method according to claim 1 , further comprising:
playing the audio included in the song list in the to-be-played song list set.

4. The method according to claim 3 , further comprising:
performing, in response to determining a preset third category keyword being included in a received second user sentence, a corresponding preset operation based on the third category keyword included in the second user sentence, the preset operation including one of: switching a currently played song list and adding the currently played song list to favourites.

determining, in response to receiving a first user sentence, whether a first category keyword of a preset first category is included in the first user sentence, the first category including at least one subcategory;
determining, in response to determining the first category keyword being included in the first user sentence, the first category keyword included in the first user sentence as a first keyword, and determine a subcategory to which the first keyword belongs, to generate a first keyword set and a subcategory set; and
selecting, based on the first keyword set and the subcategory set, a song list from a pre-generated song list set as a to-be-played song list, to generate a to-be-played song list set, the song list including at least one piece of audio and song list category information, wherein the first category keyword is preset to have a weight value, and the selecting, based on the first keyword set and the subcategory set, a song list from a pre-generated song list set as a to-be-played song list, to generate a to-be-played song list set comprises:
determining, in response to at least two first keywords being included in the first keyword set, whether a song list satisfying a preset condition is included in the pre-generated song list set, based on the at least two first keywords and subcategories to which the at least two first keywords belong;
selecting, in response to the song list satisfying the preset condition being included in the pre-generated song list set, the song list satisfying the preset condition as the to-be-played song list, to generate the to-be-played song list set;
determining, in response to the song list satisfying the preset condition being not included in the pre-generated song list set, weight values of the at least two first keywords respectively; and
selecting, based on the first keyword having the maximum weight value and a subcategory to which the first keyword having the maximum weight value belongs, a song list from the pre-generated song list set as the to-be-played song list, to generate the to-be-played song list set.
