Namespace

Methods

__construct

Constructor.

Parameters
Name	Description
`data`	`array` Optional. Data for populating the Message object.
`↳ audio_encoding`	`int` Required. Audio encoding of the audio content to process.
`↳ sample_rate_hertz`	`int` Required. Sample rate (in Hertz) of the audio content sent in the query. Refer to Cloud Speech API documentation for more details.
`↳ language_code`	`string` 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.
`↳ 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.
`↳ phrase_hints`	`array` 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`.
`↳ speech_contexts`	`array<Google\Cloud\Dialogflow\V2\SpeechContext>` Context information to assist speech recognition. See the Cloud Speech documentation for more details.
`↳ model`	`string` 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)
`↳ model_variant`	`int` Which variant of the Speech model to use.
`↳ single_utterance`	`bool` 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.
`↳ disable_no_speech_recognized_event`	`bool` Only used in Participants.AnalyzeContent and Participants.StreamingAnalyzeContent. If `false` and recognition doesn't return any result, trigger `NO_SPEECH_RECOGNIZED` event to Dialogflow agent.
`↳ enable_automatic_punctuation`	`bool` Enable automatic punctuation option at the speech backend.

getModel

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)
