Delete a custom voice

Deletes a custom voice your account created, which frees its place in the account's limit at once. The voice stops working immediately and this cannot be undone. Deleting a voice that is already gone succeeds. This endpoint adds no charge and works whatever the account's balance. Available on Qwen Audio 3.0 TTS, Qwen Audio 3.1 TTS and Qwen Audio 3.1 TTS Plus.
