EnableWordInfo

public bool EnableWordInfo { get; set; }

If true, Dialogflow returns [SpeechWordInfo][google.cloud.dialogflow.v2.SpeechWordInfo] in [StreamingRecognitionResult][google.cloud.dialogflow.v2.StreamingRecognitionResult] with information about the recognized speech words, e.g. start and end time offsets. If false or unspecified, Speech doesn't return any word-level information.

LanguageCode

The language of the supplied audio. Dialogflow does not do translations. See Language Support for a list of the currently supported language codes. Note that queries in the same session do not necessarily need to specify the same language.

Property Value
Type Description
string

Model

public string Model { get; set; }

Which Speech model to select. Select the model best suited to your domain to get best results. If a model is not explicitly specified, then Dialogflow auto-selects a model based on other parameters in the SpeechToTextConfig and Agent settings. If enhanced speech model is enabled for the agent and an enhanced version of the specified model for the language does not exist, then the speech is recognized using the standard version of the specified model. Refer to Cloud Speech API documentation for more details. If you specify a model, the following models typically have the best performance:

  • phone_call (best for Agent Assist and telephony)
  • latest_short (best for Dialogflow non-telephony)
  • command_and_search

Leave this field unspecified to use Agent Speech settings for model selection.
