Cloned (personal) voices can now be synthesized on simba-3.2. Given the model’s quality bar, each cloned voice must first be reviewed and approved by Speechify — contact us to have a voice key approved for simba-3.2 — while we evaluate stronger safeguards. This is zero-shot cloning, gated only on that manual approval step.

simba-english and simba-multilingual continue to serve cloned voices self-serve, with no approval step and no change to existing integrations; simba-multilingual still speaks one cloned voice across 30+ languages. Once Speechify has approved a cloned voice key, pass it as voice_id with model: "simba-3.2".
