Variant of the specified [Speech model][google.cloud.dialogflow.v2.InputAudioConfig.model] to use.
See the Cloud Speech
documentation
for which models have different variants. For example, the "phone_call" model
has both a standard and an enhanced variant. When you use an enhanced model,
you will generally receive higher quality results than for a standard model.
No model variant specified. In this case Dialogflow defaults to
USE_BEST_AVAILABLE.
UseBestAvailable
Use the best available variant of the [Speech
model][InputAudioConfig.model] that the caller is eligible for.
Please see the Dialogflow
docs for
how to make your project eligible for enhanced models.
UseEnhanced
Use an enhanced model variant:
If an enhanced variant does not exist for the given
[model][google.cloud.dialogflow.v2.InputAudioConfig.model] and request language, Dialogflow falls
back to the standard variant.
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.
UseStandard
Use standard model variant even if an enhanced model is available. See the
Cloud Speech
documentation
for details about enhanced models.
