> `Simba` names the model family, not the brand. Model ids: `simba-3.2` (English, recommended) 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: new model, `simba-turbo`, and Multilingual support

We now support two voice synthesis models. The original, known as `simba-base`, now supports multilingual inputs, see for the list of [supported languages](https://docs.speechify.ai/build/guides/text-to-speech/language-support) . The new model, `simba-turbo`, is English-only, but produces the audio faster.

You can select the model by passing the `model` param to our [audio APIs](/build/api-reference/v1/audio/speech). Additionally, you can pass the `language` param, when your text is 100% in one language (otherwise leave it empty and let our system detect the languages).

[Read more](/build/guides/concepts/models) about our models.

You can also make use of the model settings from our Playground.
