Reference documentation and code samples for the Dialogflow CX V3 API module Google::Cloud::Dialogflow::CX::V3::SpeechModelVariant.
Variant of the specified Speech 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.
Constants
SPEECH_MODEL_VARIANT_UNSPECIFIED
value: 0
No model variant specified. In this case Dialogflow defaults to
USE_BEST_AVAILABLE.
USE_BEST_AVAILABLE
value: 1
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.
USE_STANDARD
value: 2
Use standard model variant even if an enhanced model is available. See the
Cloud Speech
documentation
for details about enhanced models.
USE_ENHANCED
value: 3
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.
