modelVariant property

String? modelVariant
getter/setter pair

Which variant of the Speech model to use. Possible string values are:

  • "SPEECH_MODEL_VARIANT_UNSPECIFIED" : No model variant specified. In this case Dialogflow defaults to USE_BEST_AVAILABLE.
  • "USE_BEST_AVAILABLE" : Use the best available variant of the Speech model that the caller is eligible for. Please see the Dialogflow docs for how to make your project eligible for enhanced models.
  • "USE_STANDARD" : Use standard model variant even if an enhanced model is available. See the Cloud Speech documentation for details about enhanced models.
  • "USE_ENHANCED" : Use an enhanced model variant: * If an enhanced variant does not exist for the given model and request language, Dialogflow falls back to the standard variant. The Cloud Speech documentation describes which models have enhanced variants. * If the API caller isn't eligible for enhanced models, Dialogflow returns an error. Please see the Dialogflow docs for how to make your project eligible.
