Abstract: The present invention relates to a music generation method, apparatus and system, and storage medium. In an embodiment of the present disclosure: obtaining text information, and converting the text information into a corresponding voice audio; obtaining an initial music audio, wherein the initial music audio comprises a music key point, and music characteristics of the initial music audio have a sudden change at the position of an audio key point; and on the basis of the position of the music key point, synthesizing the voice audio and the initial music audio to obtain a target music audio. In the target music audio, the voice audio appears at the position of the music key point of the initial music audio. Thus, a music audio is generated from text information, and the user can customize the content of the text information and customize the initial music audio, so as to achieve the purpose of personalized music customization, thereby overcoming an existing deficiency that personalized music customization cannot be achieved.

Abstract: The present disclosure relates to a song generation method, apparatus and system, and a storage medium. The method comprises: acquiring target lyric text input by a user; aligning the target lyric text with a singing melody of an initial song, and determining a correspondence between text units in the target lyric text and notes in the singing melody; performing speech synthesis on the target lyric text on the basis of the correspondence between the text units in the target lyric text and the notes in the singing melody, so as to obtain singing speech in which the target lyric text is sung with the singing melody; and then, combining the singing speech and accompaniment audio of the initial song, so as to generate a target song. Substantively, a user is allowed to write lyrics by himself/herself, and perform song creation on the basis of the lyrics written by the user himself/herself, a singing melody and accompaniment audio, thereby forming a complete and new song. In this way, even if a user does not have professional skills in music creation, the user can generate a song on the basis of lyrics written by the user, such that the efficiency and interest of creating a song by the user are improved.
