entityTypes()

Returns the entityTypes Resource.

close()

Close httplib2 connections.

detectIntent(session, body=None, x__xgafv=None)

Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause session entity types to be updated, which in turn might affect results of future queries. Note: Always use agent versions for production traffic. See [Versions and environments](https://cloud.google.com/dialogflow/cx/docs/concept/version).

fulfillIntent(session, body=None, x__xgafv=None)

Fulfills a matched intent returned by MatchIntent. Must be called after MatchIntent, with input from MatchIntentResponse. Otherwise, the behavior is undefined.

matchIntent(session, body=None, x__xgafv=None)

Returns preliminary intent match results, doesn't change the session status.

serverStreamingDetectIntent(session, body=None, x__xgafv=None)

Processes a natural language query and returns structured, actionable data as a result through server-side streaming. Server-side streaming allows Dialogflow to send [partial responses](https://cloud.google.com/dialogflow/cx/docs/concept/fulfillment#partial-response) earlier in a single request.

detectIntent(session, body=None, x__xgafv=None)
Processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause session entity types to be updated, which in turn might affect results of future queries. Note: Always use agent versions for production traffic. See [Versions and environments](https://cloud.google.com/dialogflow/cx/docs/concept/version).

Args:
  session: string, Required. The name of the session this query is sent to. Format: `projects//locations//agents//sessions/` or `projects//locations//agents//environments//sessions/`. If `Environment ID` is not specified, we assume default 'draft' environment. It's up to the API caller to choose an appropriate `Session ID`. It can be a random number or some type of session identifiers (preferably hashed). The length of the `Session ID` must not exceed 36 characters. For more information, see the [sessions guide](https://cloud.google.com/dialogflow/cx/docs/concept/session). Note: Always use agent versions for production traffic. See [Versions and environments](https://cloud.google.com/dialogflow/cx/docs/concept/version). (required)
  body: object, The request body.
    The object takes the form of:

    "audioEncoding": "A String", # Required. Audio encoding of the synthesized audio content.
    "sampleRateHertz": 42, # Optional. The synthesis sample rate (in hertz) for this audio. If not provided, then the synthesizer will use the default sample rate based on the audio encoding. If this is different from the voice's natural sample rate, then the synthesizer will honor this request by converting to the desired sample rate (which might result in worse audio quality).
    "synthesizeSpeechConfig": { # Configuration of how speech should be synthesized. # Optional. Configuration of how speech should be synthesized. If not specified, Agent.text_to_speech_settings is applied.
      "effectsProfileId": [ # Optional. An identifier which selects 'audio effects' profiles that are applied on (post synthesized) text to speech. Effects are applied on top of each other in the order they are given.
        "A String",
      ],
      "pitch": 3.14, # Optional. Speaking pitch, in the range [-20.0, 20.0]. 20 means increase 20 semitones from the original pitch. -20 means decrease 20 semitones from the original pitch.
      "speakingRate": 3.14, # Optional. Speaking rate/speed, in the range [0.25, 4.0]. 1.0 is the normal native speed supported by the specific voice. 2.0 is twice as fast, and 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed. Any other values < 0.25 or > 4.0 will return an error.
      "voice": { # Description of which voice to use for speech synthesis. # Optional. The desired voice of the synthesized audio.
        "name": "A String", # Optional. The name of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and ssml_gender. For the list of available voices, please refer to [Supported voices and languages](https://cloud.google.com/text-to-speech/docs/voices).
        "ssmlGender": "A String", # Optional. The preferred gender of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and name. Note that this is only a preference, not requirement. If a voice of the appropriate gender is not available, the synthesizer substitutes a voice with a different gender rather than failing the request.
      },
      "volumeGainDb": 3.14, # Optional. Volume gain (in dB) of the normal native volume supported by the specific voice, in the range [-96.0, 16.0]. If unset, or set to a value of 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB) will play at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) will play at approximately twice the amplitude of the normal native signal amplitude. We strongly recommend not to exceed +10 (dB) as there's usually no effective increase in loudness for any value greater than that.
    },
  },
  "queryInput": { # Represents the query input. It can contain one of: 1. A conversational query in the form of text. 2. An intent query that specifies which intent to trigger. 3. Natural language speech audio to be processed. 4. An event to be triggered. 5. DTMF digits to invoke an intent and fill in parameter value. 6. The results of a tool executed by the client. # Required. The input specification.
    "audio": { # Represents the natural speech audio to be processed. # The natural language speech audio to be processed.
      "audio": "A String", # The natural language speech audio to be processed. A single request can contain up to 2 minutes of speech audio data. The transcribed text cannot contain more than 256 bytes. For non-streaming audio detect intent, both `config` and `audio` must be provided. For streaming audio detect intent, `config` must be provided in the first request and `audio` must be provided in all following requests.
      "config": { # Instructs the speech recognizer on how to process the audio content. # Required. Instructs the speech recognizer how to process the speech audio.
        "audioEncoding": "A String", # Required. Audio encoding of the audio content to process.
        "bargeInConfig": { # Configuration of the barge-in behavior. Barge-in instructs the API to return a detected utterance at a proper time while the client is playing back the response audio from a previous request. When the client sees the utterance, it should stop the playback and immediately get ready for receiving the responses for the current request. The barge-in handling requires the client to start streaming audio input as soon as it starts playing back the audio from the previous response. The playback is modeled into two phases: * No barge-in phase: which goes first and during which speech detection should not be carried out. * Barge-in phase: which follows the no barge-in phase and during which the API starts speech detection and may inform the client that an utterance has been detected. Note that no-speech event is not expected in this phase. The client provides this configuration in terms of the durations of those two phases. The durations are measured in terms of the audio length from the start of the input audio. No-speech event is a response with END_OF_UTTERANCE without any transcript following up. # Configuration of barge-in behavior during the streaming of input audio.
          "noBargeInDuration": "A String", # Duration that is not eligible for barge-in at the beginning of the input audio.
          "totalDuration": "A String", # Total duration for the playback at the beginning of the input audio.

This field will be deprecated once force migration takes place in June 2024. Please refer to [Dialogflow CX Speech model migration](https://cloud.google.com/dialogflow/cx/docs/concept/speech-model-migration).
        "phraseHints": [ # Optional. A list of strings containing words and phrases that the speech recognizer should recognize with higher likelihood. See [the Cloud Speech documentation](https://cloud.google.com/speech-to-text/docs/basics#phrase-hints) for more details.
          "A String",
        ],
        "sampleRateHertz": 42, # Sample rate (in Hertz) of the audio content sent in the query. Refer to [Cloud Speech API documentation](https://cloud.google.com/speech-to-text/docs/basics) for more details.
        "singleUtterance": True or False, # Optional. 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.

matchIntent(session, body=None, x__xgafv=None)
Returns preliminary intent match results, doesn't change the session status.

Args:
  session: string, Required. The name of the session this query is sent to. Format: `projects//locations//agents//sessions/` or `projects//locations//agents//environments//sessions/`. If `Environment ID` is not specified, we assume default 'draft' environment. It's up to the API caller to choose an appropriate `Session ID`. It can be a random number or some type of session identifiers (preferably hashed). The length of the `Session ID` must not exceed 36 characters. For more information, see the [sessions guide](https://cloud.google.com/dialogflow/cx/docs/concept/session). (required)
  body: object, The request body.
    The object takes the form of:

{ # Request of MatchIntent.
  "persistParameterChanges": True or False, # Persist session parameter changes from `query_params`.
  "queryInput": { # Represents the query input. It can contain one of: 1. A conversational query in the form of text. 2. An intent query that specifies which intent to trigger. 3. Natural language speech audio to be processed. 4. An event to be triggered. 5. DTMF digits to invoke an intent and fill in parameter value. 6. The results of a tool executed by the client. # Required. The input specification.
    "audio": { # Represents the natural speech audio to be processed. # The natural language speech audio to be processed.
      "audio": "A String", # The natural language speech audio to be processed. A single request can contain up to 2 minutes of speech audio data. The transcribed text cannot contain more than 256 bytes. For non-streaming audio detect intent, both `config` and `audio` must be provided. For streaming audio detect intent, `config` must be provided in the first request and `audio` must be provided in all following requests.
      "config": { # Instructs the speech recognizer on how to process the audio content. # Required. Instructs the speech recognizer how to process the speech audio.
        "audioEncoding": "A String", # Required. Audio encoding of the audio content to process.
        "bargeInConfig": { # Configuration of the barge-in behavior. Barge-in instructs the API to return a detected utterance at a proper time while the client is playing back the response audio from a previous request. When the client sees the utterance, it should stop the playback and immediately get ready for receiving the responses for the current request. The barge-in handling requires the client to start streaming audio input as soon as it starts playing back the audio from the previous response. The playback is modeled into two phases: * No barge-in phase: which goes first and during which speech detection should not be carried out. * Barge-in phase: which follows the no barge-in phase and during which the API starts speech detection and may inform the client that an utterance has been detected. Note that no-speech event is not expected in this phase. The client provides this configuration in terms of the durations of those two phases. The durations are measured in terms of the audio length from the start of the input audio. No-speech event is a response with END_OF_UTTERANCE without any transcript following up. # Configuration of barge-in behavior during the streaming of input audio.
          "noBargeInDuration": "A String", # Duration that is not eligible for barge-in at the beginning of the input audio.

        "sampleRateHertz": 42, # Sample rate (in Hertz) of the audio content sent in the query. Refer to [Cloud Speech API documentation](https://cloud.google.com/speech-to-text/docs/basics) for more details.
        "singleUtterance": True or False, # Optional. 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.

A `sys.no-match-default` or `sys.no-input-default` handler will be used to handle all following no-match/no-input events after all numbered no-match/no-input handlers for the parameter are consumed. A `sys.invalid-parameter` handler can be defined to handle the case where the parameter values have been `invalidated` by webhook. For example, if the user's response fill the parameter, however the parameter was invalidated by webhook, the fulfillment associated with the `sys.invalid-parameter` handler (if defined) will be called to provide a prompt. If the event handler for the corresponding event can't be found on the parameter, `initial_prompt_fulfillment` will be re-prompted.

serverStreamingDetectIntent(session, body=None, x__xgafv=None)
Processes a natural language query and returns structured, actionable data as a result through server-side streaming. Server-side streaming allows Dialogflow to send [partial responses](https://cloud.google.com/dialogflow/cx/docs/concept/fulfillment#partial-response) earlier in a single request.

Args:
  session: string, Required. The name of the session this query is sent to. Format: `projects//locations//agents//sessions/` or `projects//locations//agents//environments//sessions/`. If `Environment ID` is not specified, we assume default 'draft' environment. It's up to the API caller to choose an appropriate `Session ID`. It can be a random number or some type of session identifiers (preferably hashed). The length of the `Session ID` must not exceed 36 characters. For more information, see the [sessions guide](https://cloud.google.com/dialogflow/cx/docs/concept/session). Note: Always use agent versions for production traffic. See [Versions and environments](https://cloud.google.com/dialogflow/cx/docs/concept/version). (required)
  body: object, The request body.
    The object takes the form of:

{ # The request to detect user's intent.
  "outputAudioConfig": { # Instructs the speech synthesizer how to generate the output audio content. # Instructs the speech synthesizer how to generate the output audio.
    "audioEncoding": "A String", # Required. Audio encoding of the synthesized audio content.
    "sampleRateHertz": 42, # Optional. The synthesis sample rate (in hertz) for this audio. If not provided, then the synthesizer will use the default sample rate based on the audio encoding. If this is different from the voice's natural sample rate, then the synthesizer will honor this request by converting to the desired sample rate (which might result in worse audio quality).
    "synthesizeSpeechConfig": { # Configuration of how speech should be synthesized. # Optional. Configuration of how speech should be synthesized. If not specified, Agent.text_to_speech_settings is applied.
      "effectsProfileId": [ # Optional. An identifier which selects 'audio effects' profiles that are applied on (post synthesized) text to speech. Effects are applied on top of each other in the order they are given.
        "A String",
      ],
      "pitch": 3.14, # Optional. Speaking pitch, in the range [-20.0, 20.0]. 20 means increase 20 semitones from the original pitch. -20 means decrease 20 semitones from the original pitch.
      "speakingRate": 3.14, # Optional. Speaking rate/speed, in the range [0.25, 4.0]. 1.0 is the normal native speed supported by the specific voice. 2.0 is twice as fast, and 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed. Any other values < 0.25 or > 4.0 will return an error.
      "voice": { # Description of which voice to use for speech synthesis. # Optional. The desired voice of the synthesized audio.
        "name": "A String", # Optional. The name of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and ssml_gender. For the list of available voices, please refer to [Supported voices and languages](https://cloud.google.com/text-to-speech/docs/voices).
        "ssmlGender": "A String", # Optional. The preferred gender of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and name. Note that this is only a preference, not requirement. If a voice of the appropriate gender is not available, the synthesizer substitutes a voice with a different gender rather than failing the request.
      },
      "volumeGainDb": 3.14, # Optional. Volume gain (in dB) of the normal native volume supported by the specific voice, in the range [-96.0, 16.0]. If unset, or set to a value of 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB) will play at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) will play at approximately twice the amplitude of the normal native signal amplitude. We strongly recommend not to exceed +10 (dB) as there's usually no effective increase in loudness for any value greater than that.
    },
  },

The results of a tool executed by the client. # Required. The input specification.
    "audio": { # Represents the natural speech audio to be processed. # The natural language speech audio to be processed.
      "audio": "A String", # The natural language speech audio to be processed. A single request can contain up to 2 minutes of speech audio data.

        "bargeInConfig": { # Configuration of the barge-in behavior. Barge-in instructs the API to return a detected utterance at a proper time while the client is playing back the response audio from a previous request. When the client sees the utterance, it should stop the playback and immediately get ready for receiving the responses for the current request. The barge-in handling requires the client to start streaming audio input as soon as it starts playing back the audio from the previous response. The playback is modeled into two phases: * No barge-in phase: which goes first and during which speech detection should not be carried out. * Barge-in phase: which follows the no barge-in phase and during which the API starts speech detection and may inform the client that an utterance has been detected. Note that no-speech event is not expected in this phase. The client provides this configuration in terms of the durations of those two phases. The durations are measured in terms of the audio length from the start of the input audio. No-speech event is a response with END_OF_UTTERANCE without any transcript following up. # Configuration of barge-in behavior during the streaming of input audio.
          "noBargeInDuration": "A String", # Duration that is not eligible for barge-in at the beginning of the input audio.

        "sampleRateHertz": 42, # Sample rate (in Hertz) of the audio content sent in the query. Refer to [Cloud Speech API documentation](https://cloud.google.com/speech-to-text/docs/basics) for more details.
        "singleUtterance": True or False, # Optional. 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.

  An object of the form:

    { # The message returned from the DetectIntent method.
  "allowCancellation": True or False, # Indicates whether the partial response can be cancelled when a later response arrives. e.g. if the agent specified some music as partial response, it can be cancelled.
  "outputAudio": "A String", # The audio data bytes encoded as specified in the request. Note: The output audio is generated based on the values of default platform text responses found in the `query_result.response_messages` field. If multiple default text responses exist, they will be concatenated when generating audio. If no default platform text responses exist, the generated audio content will be empty. In some scenarios, multiple output audio fields may be present in the response structure. In these cases, only the top-most-level audio output has content.
  "outputAudioConfig": { # Instructs the speech synthesizer how to generate the output audio content. # The config used by the speech synthesizer to generate the output audio.
    "audioEncoding": "A String", # Required. Audio encoding of the synthesized audio content.
    "sampleRateHertz": 42, # Optional. The synthesis sample rate (in hertz) for this audio. If not provided, then the synthesizer will use the default sample rate based on the audio encoding. If this is different from the voice's natural sample rate, then the synthesizer will honor this request by converting to the desired sample rate (which might result in worse audio quality).
    "synthesizeSpeechConfig": { # Configuration of how speech should be synthesized. # Optional. Configuration of how speech should be synthesized. If not specified, Agent.text_to_speech_settings is applied.
      "effectsProfileId": [ # Optional. An identifier which selects 'audio effects' profiles that are applied on (post synthesized) text to speech. Effects are applied on top of each other in the order they are given.
        "A String",
      ],
      "pitch": 3.14, # Optional. Speaking pitch, in the range [-20.0, 20.0]. 20 means increase 20 semitones from the original pitch. -20 means decrease 20 semitones from the original pitch.
      "speakingRate": 3.14, # Optional. Speaking rate/speed, in the range [0.25, 4.0]. 1.0 is the normal native speed supported by the specific voice. 2.0 is twice as fast, and 0.5 is half as fast. If unset(0.0), defaults to the native 1.0 speed. Any other values < 0.25 or > 4.0 will return an error.
      "voice": { # Description of which voice to use for speech synthesis. # Optional. The desired voice of the synthesized audio.
        "name": "A String", # Optional. The name of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and ssml_gender. For the list of available voices, please refer to [Supported voices and languages](https://cloud.google.com/text-to-speech/docs/voices).
        "ssmlGender": "A String", # Optional. The preferred gender of the voice. If not set, the service will choose a voice based on the other parameters such as language_code and name. Note that this is only a preference, not requirement. If a voice of the appropriate gender is not available, the synthesizer substitutes a voice with a different gender rather than failing the request.
      },
      "volumeGainDb": 3.14, # Optional. Volume gain (in dB) of the normal native volume supported by the specific voice, in the range [-96.0, 16.0]. If unset, or set to a value of 0.0 (dB), will play at normal native signal amplitude. A value of -6.0 (dB) will play at approximately half the amplitude of the normal native signal amplitude. A value of +6.0 (dB) will play at approximately twice the amplitude of the normal native signal amplitude. We strongly recommend not to exceed +10 (dB) as there's usually no effective increase in loudness for any value greater than that.
