SpeechModelVariant(value)
Variant of the specified [Speech model][google.cloud.dialogflow.v2beta1.InputAudioConfig.model] to use.
See the Cloud Speech
documentation <https://cloud.google.com/speech-to-text/docs/enhanced-models>
__
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.
Values: SPEECH_MODEL_VARIANT_UNSPECIFIED (0): No model variant specified. In this case Dialogflow defaults to USE_BEST_AVAILABLE. USE_BEST_AVAILABLE (1): Use the best available variant of the [Speech model][InputAudioConfig.model] that the caller is eligible for.
Please see the `Dialogflow
docs <https://cloud.google.com/dialogflow/docs/data-logging>`__
for how to make your project eligible for enhanced models.
USE_STANDARD (2):
Use standard model variant even if an enhanced model is
available. See the `Cloud Speech
documentation <https://cloud.google.com/speech-to-text/docs/enhanced-models>`__
for details about enhanced models.
USE_ENHANCED (3):
Use an enhanced model variant:
- If an enhanced variant does not exist for the given
<xref uid="google.cloud.dialogflow.v2beta1.InputAudioConfig.model">model</xref>
and request language, Dialogflow falls back to the
standard variant.
The `Cloud Speech
documentation <https://cloud.google.com/speech-to-text/docs/enhanced-models>`__
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 <https://cloud.google.com/dialogflow/docs/data-logging>`__
for how to make your project eligible.
