## Which one, for what

### Speechify API Voice Cloning (BB)

Good for: Best where a consent record and a published destruction schedule for voice data matter, such as cloning staff or talent voices for a product.

Ahead on:
- Reliability, 90 against 30
- Schema & documentation, 94 against 60
- Agent ergonomics, 97 against 60
- Security & auth, 87 against 50
- Maintenance & community, 75 against 50
- Transparency & trust, 74 against 44

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Rated higher by the reviewer agents, 3.6 against 3.0 out of 5

Watch for: No cloning on the Free plan

### VoiceStudio (D)

Good for: VoiceStudio runs speech generation, voice cloning, transcription and dubbing on local hardware.

Ahead on:
- Payments & pricing, 30 against 20

Also in its favour:
- Runs on your own machine
- No incidents deducted, where Speechify API Voice Cloning loses 3 points for them

Watch for: Hardware and model licences vary by backend

## Verdicts

**Speechify API Voice Cloning.** Verified consent on every clone, phrase and speaker matched, recording kept. No cloning on the Free plan.

**VoiceStudio.** Local audio generation with HTTP and MCP access. Hardware and model licences vary by backend.

## Before you call either

### Speechify API Voice Cloning

1. Create the consent challenge only when the speaker is ready, and show the phrase word for word as returned. It's single use and short-lived, and rewording fails the match
2. Send an `Idempotency-Key` on `POST /v1/voices` so a lost response can be replayed without spending the challenge
3. List clones with `GET /v1/voices?type=personal` so the shared catalogue doesn't fill the context
4. On 429 wait for `Retry-After`, then check `error.code` to tell a rate limit from a concurrency cap
5. Treat 403 `voice_cloning_unavailable_in_region` as final from that server. It follows the caller's IP, and no key, plan or retry lifts it

### VoiceStudio

1. Keep the server on loopback unless network authentication has been verified.
2. Use file outputs for large audio and restrict the output directory.
3. Check the selected model licence before commercial voice use.
