Persona

Two families. Clone Voice and Init + Complete are both Voice Persona — same result, different billing.

A persona is a reusable vocal identity for /generate. Do not mix Clip Persona with Voice Persona.

Clip Persona

Style / vocal color from an existing Suno clip. Desensitized — any account can use it.

Create Clip Persona

Sync create from clip_id. Not voiceprint-bound. /generate keeps is_voice: false.

Get Vox Stem

Extract vocals (vocal_start_s / vocal_end_s optional, default 45–74), then pass vox_audio_id into Clip Persona (persona_type: "vox").

Voice Persona

Real-voice clone, voiceprint-bound to the creating account. Two APIs, same Voice Persona:

Clone Voice

POST /suno/v2/voices — one audio_url, one task. Paid. Internal phrase + TTS verify.

Init + Complete

User reads phrase_text. Free. Multi-language. Same Voice Persona as Clone Voice.

 Clone Voice  /voices     (paid, 1 call)
      └─ same pipeline as ──►  init  +  complete   (free, 2 calls)
                                    │
                                    ▼
                              Voice Persona
                              is_voice: true

	Clone Voice `/voices`	Init → Complete
Family	Voice Persona	Voice Persona
Result	Poll `/status` for `persona_id` (and `artist_clip_id` if present)	Same Voice Persona
Billing	Paid (failed tasks should not be billed)	Free
Input	Public `audio_url`	Voice file + live read-aloud
UI	No phrase / no second recording	Show `phrase_text`, record within ~30s
`is_public`	Optional; default `false` (plaza if `true`)	Optional on complete
`is_voice`	`true`	`true`
Account	Creating account only	Creating account only

Need a URL and no read-aloud UI → Clone Voice (paid). User can read a phrase → Init + Complete (free). /generate with is_voice: true only needs persona_id.

Clone Voice task result

After polling /suno/v2/status to success, data looks like this:

{
  "name": "voices-ext-fix-verify",
  "is_public": false,
  "persona_id": "af88153e-a513-432a-a9b5-3948fb562d4b",
  "artist_clip_id": "clip_abc123"
}

On /generate send persona_id + is_voice: true. artist_clip_id is optional for Voice Persona.

Desensitization vs voiceprint

	Clip Persona	Voice Persona (Clone Voice or Init+Complete)
Desensitized?	Yes	No — voiceprint-bound
Who can use it	Any account	Same Suno account only
`is_voice`	`false`	`true`
Input	`clip_id` (+ optional `vox_audio_id`)	A real voice recording

A Voice Persona with is_voice: false, or on another account, fails. A Clip Persona must not set is_voice: true.

Use on `/generate`

{
  "task": "create",
  "model": "chirp-v6",
  "prompt": "[Verse]\n...",
  "persona": {
    "persona_id": "af88153e-a513-432a-a9b5-3948fb562d4b",
    "is_voice": true
  }
}

Field	Required	Notes
`persona_id`	Yes	From Clip create, or Clone Voice / Init+Complete poll `data`
`artist_clip_id`	Clip Persona: yes. Voice Persona (`is_voice: true`): optional (`persona_id` alone selects task vox)
`artist_start_s` / `artist_end_s`	No	Vocal range on the clip (seconds). Omit = whole clip
`persona_style`	No	Only `"vox"` on chirp-v50+
`is_voice`	No	`true` for Voice Persona only
