Changelog

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).

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.
