> `Simba` names the model family, not the brand. Model ids: `simba-3.5` (48 languages under one id, English included; recommended), `simba-3.2` (English) and `simba-3.0` (English, German, Spanish, French, Italian and Portuguese; the default). `simba-english` and `simba-multilingual` are retired: a new workspace that sends either gets `400 model_retired`. `SimbaVoice` / `simbavoice.ai` are retired.

# API: `simba-3.0` now supports cloned/personal voices

`simba-3.0` now accepts cloned and personal voices on `POST /v1/audio/speech` and `POST /v1/audio/stream`. Pass a cloned voice's `voice_id` with `model: "simba-3.0"`, the same way you would with `simba-english`. Zero-shot clones (from a 10-30 second sample) are supported self-serve; fine-tuned voices remain on `simba-english` and `simba-multilingual` (contact sales).

```json
{
  "input": "This is my cloned voice speaking.",
  "voice_id": "voice_demo0001",
  "model": "simba-3.0"
}
```

`simba-3.2` also supports voice cloning, but each cloned voice currently requires manual Speechify approval of the voice key before use. For self-serve cloned-voice synthesis without approval, use `simba-3.0`, `simba-english`, or `simba-multilingual`.
