# Suno Voice Regenerate Verification Phrase

`POST /api/v1/voice/regenerate`

Regenerate the validation phrase for an existing Suno Voice task.

Use this endpoint when the previous validation phrase failed, expired, or the user needs a new phrase to record. Submit the existing `taskId`; the system will start a new validation phrase generation task and return a task ID for polling.

## Query Task Status

After submitting the regeneration task, check the new validation phrase result through the validation phrase query endpoint:

## Continue the Flow

Once the regenerated phrase is ready, ask the user to record the new phrase and submit the verification audio to the voice generation endpoint. For best voice generation results, singing is recommended.
