Notes

  • If no language_id filter is provided, all providers are returned
  • Not all providers support all languages — use the language_id filter to get compatible providers
  • Synthesizer providers are only relevant for pipeline and dualplex modes (multimodal mode handles TTS internally)
  • If you don’t set synthesizer_provider_id when creating an assistant, the language’s default provider is used
