Notes

  • If language_id is not provided, all providers are returned.
  • Not every provider supports all languages – use the language_id filter to find compatible providers.
  • Synthesizer providers are only relevant for the pipeline and dualplex modes (in multimodal mode, TTS is handled internally).
  • If you do not set synthesizer_provider_id when creating an assistant, the default provider for the language is used.
