Usage Guide

  • Use this endpoint after the custom voice generation task succeeds.
  • Submit the related task ID in task_id.
  • If isAvailable is true, the generated voice is ready for supported Suno generation workflows.

​
When to Use

Call this endpoint before starting a generation request that depends on a custom voice. It helps avoid submitting downstream tasks while the voice is still unavailable.
