Properties
AudioEncoding
public AudioEncoding AudioEncoding { get; set; }Required. Audio encoding of the audio content to process.
| Property Value | |
|---|---|
| Type | Description |
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.

EnableAutomaticPunctuation
public bool EnableAutomaticPunctuation { get; set; }Enable automatic punctuation option at the speech backend.
| Property Value | |
|---|---|
| Type | Description |
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 | |
|---|---|
| Type | Description |
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 | |
|---|---|
| Type | Description |
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 | |
|---|---|
| Type | Description |
string | |
ModelVariant
public SpeechModelVariant ModelVariant { get; set; }Which variant of the [Speech model][google.cloud.dialogflow.v2.InputAudioConfig.model] to use.
| Property Value | |
|---|---|
| Type | Description |
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 | |
|---|---|
| Type | Description |
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 | |
|---|---|
| Type | Description |
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.

SpeechContexts
public RepeatedField<SpeechContext> SpeechContexts { get; }Context information to assist speech recognition.
