Reference documentation and code samples for the Dialogflow CX V3 API module Google::Cloud::Dialogflow::CX::V3::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.
