Reference documentation and code samples for the Dialogflow v3 API enum SpeechModelVariant.
Variant of the specified [Speech
model][google.cloud.dialogflow.cx.v3.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.
UseEnhanced
Use an enhanced model variant:
If an enhanced variant does not exist for the given
[model][google.cloud.dialogflow.cx.v3.InputAudioConfig.model] and request
language, Dialogflow falls back to the standard variant.
