The acapella must be in singing form; normal speech is not supported.
Outputs: voice_id and instrumental_id.

If purpose is voice:

You need to upload a file containing only acapella in singing form (normal speech audio is not supported).
Output: voice_id.

If purpose is instrumental:

You need to upload a file containing only accompaniment.
Output: instrumental_id.

Body

lyricsstringRequired

Lyrics with optional formatting. You can use a newline to separate each line of lyrics. You can use two newlines to add a pause between lines. You can use double hash marks (##) at the beginning and end of the lyrics to add accompaniment. Maximum 600 characters.

Example:

##Swift and Boundless In the realm of innovation, where visions align, AIML API's the name, making tech shine. Intelligent solutions, breaking the mold, Swift inference power, bold and untold. ##

modelundefined · enumRequiredPossible values:

refer_voicestringOptional

voice_id. At least one of refer_voice or refer_instrumental is required. When only refer_voice is provided, the system can still output music data. The generated music will be an a cappella vocal hum that aligns with the provided refer_voice and the generated lyrics, without any instrumental accompaniment.

Example: vocal-2025010100000000-a0AAAaaa

refer_instrumentalstringOptional

instrumental_id. At least one of refer_voice or refer_instrumental is required. When only refer_instrumental is provided, the system can still output music data. The generated music will be a purely instrumental track that aligns with the provided refer_instrumental, without any vocals.

Example: instrumental-2025010100000000-Aaa0aAaA
