Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ speech_model_variant int

The speech model used in speech to text. SPEECH_MODEL_VARIANT_UNSPECIFIED, USE_BEST_AVAILABLE will be treated as USE_ENHANCED. It can be overridden in AnalyzeContentRequest and StreamingAnalyzeContentRequest request. If enhanced model variant is specified and an enhanced version of the specified model for the language does not exist, then it would emit an error.
↳ model string

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.
↳ audio_encoding int

Audio encoding of the audio content to process.
↳ sample_rate_hertz int

Sample rate (in Hertz) of the audio content sent in the query. Refer to Cloud Speech API documentation for more details.
↳ language_code string

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.
↳ enable_word_info bool

If true, Dialogflow returns SpeechWordInfo in 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.
↳ use_timeout_based_endpointing bool

Use timeout based endpointing, interpreting endpointer sensitivy as seconds of timeout value.
