Class SpeechModelVariant (2.43.0) 

SpeechModelVariant(value)

Variant of the specified [Speech model][google.cloud.dialogflow.v2.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.

    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.v2.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.
