speechModelVariant property

String? speechModelVariant
getter/setter pair

The speech model used in speech to text.

SPEECH_MODEL_VARIANT_UNSPECIFIED, USE_BEST_AVAILABLE will be treated as USE_ENHANCED. It can be overridden in AnalyzeContentRequest and StreamingAnalyzeContentRequest request. If enhanced model variant is specified and an enhanced version of the specified model for the language does not exist, then it would emit an error. 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.
