Properties

AudioEncoding

public AudioEncoding AudioEncoding { get; set; }

Required. Audio encoding of the audio content to process.

Property Value
TypeDescription
AudioEncoding

DisableNoSpeechRecognizedEvent

public bool DisableNoSpeechRecognizedEvent { get; set; }

Only used in [Participants.AnalyzeContent][google.cloud.dialogflow.v2.Participants.AnalyzeContent] and [Participants.StreamingAnalyzeContent][google.cloud.dialogflow.v2.Participants.StreamingAnalyzeContent]. If false and recognition doesn't return any result, trigger NO_SPEECH_RECOGNIZED event to Dialogflow agent.

Property Value
TypeDescription
bool

EnableAutomaticPunctuation

public bool EnableAutomaticPunctuation { get; set; }

Enable automatic punctuation option at the speech backend.

Property Value
TypeDescription
bool

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.

Property Value
TypeDescription
bool

LanguageCode

public string LanguageCode { get; set; }

Required. 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
TypeDescription
string

Model

public string Model { get; set; }

Which Speech model to select for the given request. Select the model best suited to your domain to get best results. If a model is not explicitly specified, then we auto-select a model based on the parameters in the InputAudioConfig. 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 (best for very short utterances and commands)
Property Value
TypeDescription
string

ModelVariant

public SpeechModelVariant ModelVariant { get; set; }

Which variant of the [Speech model][google.cloud.dialogflow.v2.InputAudioConfig.model] to use.

Property Value
TypeDescription
SpeechModelVariant

PhraseHints

[Obsolete]
public RepeatedField<string> PhraseHints { get; }

A list of strings containing words and phrases that the speech recognizer should recognize with higher likelihood.

See the Cloud Speech documentation for more details.

This field is deprecated. Please use speech_contexts instead. If you specify both phrase_hints and speech_contexts, Dialogflow will treat the phrase_hints as a single additional SpeechContext.

Property Value
TypeDescription
RepeatedFieldstring

SampleRateHertz

public int SampleRateHertz { get; set; }

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

Property Value
TypeDescription
int

SingleUtterance

public bool SingleUtterance { get; set; }

If false (default), recognition does not cease until the client closes the stream. If true, the recognizer will detect a single spoken utterance in input audio. Recognition ceases when it detects the audio's voice has stopped or paused. In this case, once a detected intent is received, the client should close the stream and start a new request with a new stream as needed. Note: This setting is relevant only for streaming methods. Note: When specified, InputAudioConfig.single_utterance takes precedence over StreamingDetectIntentRequest.single_utterance.

Property Value
TypeDescription
bool

SpeechContexts

public RepeatedField<SpeechContext> SpeechContexts { get; }

Context information to assist speech recognition.

See the Cloud Speech documentation for more details.

Property Value
TypeDescription
RepeatedFieldSpeechContext
