After deletion the voice is treated as non-existent by every subsequent query and generation. This cannot be undone.Only self-created voices can be deleted here. Purchased market voices are out of scope — passing one of their ids returns VOICE_NOT_FOUND. If the voice came from the asset library or the community, the source-side reference count is decremented as part of the delete.Deleting does not cancel jobs already submitted or synthesising, and does not refund credits already frozen. The response is just { status: 200 } with no data.Deprecated alias: /api/tts/voice/{id}. See the site document "Versions and migration".
