Agents

Agents are best described as Natural Language Understanding (NLU) modules that transform user requests into actionable data. You can include agents in your app, product, or service to determine user intent and respond to the user in a natural way.

After you create an agent, you can add Intents, Contexts, Entity Types, Webhooks, and so on to manage the flow of a conversation and match user input to predefined intents and actions.

You can create an agent using both Dialogflow Standard Edition and Dialogflow Enterprise Edition. For details, see Dialogflow Editions.

You can save your agent for backup or versioning by exporting the agent by using the ExportAgent method. You can import a saved agent by using the ImportAgent method.

Dialogflow provides several prebuilt agents for common conversation scenarios such as determining a date and time, converting currency, and so on.

For more information about agents, see the Dialogflow documentation.

ExportAgent
rpc ExportAgent(ExportAgentRequest) returns (Operation) Exports the specified agent to a ZIP file. Operation <response: ExportAgentResponse> Authorization Scopes Requires one of the following OAuth scopes: https://www.googleapis.com/auth/cloud-platform https://www.googleapis.com/auth/dialogflow For more information, see the Authentication Overview.

Contexts

A context represents additional information included with user input or with an intent returned by the Dialogflow API. Contexts are helpful for differentiating user input which may be vague or have a different meaning depending on additional details from your application such as user setting and preferences, previous user input, where the user is in your application, geographic location, and so on.

You can include contexts as input parameters of a DetectIntent (or StreamingDetectIntent) request, or as output contexts included in the returned intent. Contexts expire when an intent is matched, after the number of DetectIntent requests specified by the lifespan_count parameter, or after 20 minutes if no intents are matched for a DetectIntent request.

For more information about contexts, see the Dialogflow documentation.

EntityTypes

Entities are extracted from user input and represent parameters that are meaningful to your application. For example, a date range, a proper name such as a geographic location or landmark, and so on. Entities represent actionable data for your application.

When you define an entity, you can also include synonyms that all map to that entity. For example, "soft drink", "soda", "pop", and so on.

There are three types of entities:

• System - entities that are defined by the Dialogflow API for common data types such as date, time, currency, and so on. A system entity is represented by the EntityType type.

• Developer - entities that are defined by you that represent actionable data that is meaningful to your application. For example, you could define a pizza.sauce entity for red or white pizza sauce, a pizza.cheese entity for the different types of cheese on a pizza, a pizza.topping entity for different toppings, and so on. A developer entity is represented by the EntityType type.

• User - entities that are built for an individual user such as favorites, preferences, playlists, and so on. A user entity is represented by the SessionEntityType type.

For more information about entity types, see the Dialogflow documentation.

Intents

An intent represents a mapping between input from a user and an action to be taken by your application. When you pass user input to the DetectIntent (or StreamingDetectIntent) method, the Dialogflow API analyzes the input and searches for a matching intent. If no match is found, the Dialogflow API returns a fallback intent (is_fallback = true).

You can provide additional information for the Dialogflow API to use to match user input to an intent by adding the following to your intent.

• Contexts - provide additional context for intent analysis. For example, if an intent is related to an object in your application that plays music, you can provide a context to determine when to match the intent if the user input is "turn it off". You can include a context that matches the intent when there is previous user input of "play music", and not when there is previous user input of "turn on the light".

• Events - allow for matching an intent by using an event name instead of user input. Your application can provide an event name and related parameters to the Dialogflow API to match an intent. For example, when your application starts, you can send a welcome event with a user name parameter to the Dialogflow API to match an intent with a personalized welcome message for the user.

• Training phrases - provide examples of user input to train the Dialogflow API agent to better match intents.

For more information about intents, see the Dialogflow documentation.

Agent

Represents a conversational agent.

Fields
parent	string Required. The project of this agent. Format: projects/<Project ID>.
display_name	string Required. The name of this agent.
default_language_code	string Required. The default language of the agent as a language tag. See Language Support for a list of the currently supported language codes. This field cannot be set by the Update method.
supported_language_codes[]	string Optional. The list of all languages supported by this agent (except for the default_language_code).
time_zone	string Required. The time zone of this agent from the time zone database, e.g., America/New_York, Europe/Paris.
description	string Optional. The description of this agent. The maximum length is 500 characters. If exceeded, the request is rejected.
avatar_uri	string Optional. The URI of the agent's avatar. Avatars are used throughout the Dialogflow console and in the self-hosted Web Demo integration.
enable_logging	bool Optional. Determines whether this agent should log conversation queries.
match_mode	MatchMode Optional. Determines how intents are detected from user queries.
classification_threshold	float Optional. To filter out false positive results and still get variety in matched natural language inputs for your agent, you can tune the machine learning classification threshold. If the returned score value is less than the threshold value, then a fallback intent will be triggered or, if there are no fallback intents defined, no intent will be triggered. The score values range from 0.0 (completely uncertain) to 1.0 (completely certain). If set to 0.0, the default of 0.3 is used.

MatchMode

Match mode determines how intents are detected from user queries.

Enums
MATCH_MODE_UNSPECIFIED	Not specified.
MATCH_MODE_HYBRID	Best for agents with a small number of examples in intents and/or wide use of templates syntax and composite entities.
MATCH_MODE_ML_ONLY	Can be used for agents with a large number of examples in intents, especially the ones using @sys.any or very large developer entities.

AudioEncoding

Audio encoding of the audio content sent in the conversational query request. Refer to the Cloud Speech API documentation for more details.

Enums
AUDIO_ENCODING_UNSPECIFIED	Not specified.
AUDIO_ENCODING_LINEAR_16	Uncompressed 16-bit signed little-endian samples (Linear PCM).
AUDIO_ENCODING_FLAC	FLAC (Free Lossless Audio Codec) is the recommended encoding because it is lossless (therefore recognition is not compromised) and requires only about half the bandwidth of LINEAR16. FLAC stream encoding supports 16-bit and 24-bit samples, however, not all fields in STREAMINFO are supported.
AUDIO_ENCODING_MULAW	8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
AUDIO_ENCODING_AMR	Adaptive Multi-Rate Narrowband codec. sample_rate_hertz must be 8000.
AUDIO_ENCODING_AMR_WB	Adaptive Multi-Rate Wideband codec. sample_rate_hertz must be 16000.
AUDIO_ENCODING_OGG_OPUS	Opus encoded audio frames in Ogg container (OggOpus). sample_rate_hertz must be 16000.
AUDIO_ENCODING_SPEEX_WITH_HEADER_BYTE	Although the use of lossy encodings is not recommended, if a very low bitrate encoding is required, OGG_OPUS is highly preferred over Speex encoding. The Speex encoding supported by Dialogflow API has a header byte in each block, as in MIME type audio/x-speex-with-header-byte. It is a variant of the RTP Speex encoding defined in RFC 5574. The stream is a sequence of blocks, one block per RTP packet. Each block starts with a byte containing the length of the block, in bytes, followed by one or more frames of Speex data, padded to an integral number of bytes (octets) as specified in RFC 5574. In other words, each RTP header is replaced with a single byte containing the block length. Only Speex wideband is supported. sample_rate_hertz must be 16000.

Only two of the responses contain final results (#4 and #8 indicated by is_final: true). Concatenating these generates the full transcript: "to be or not to be that is the question".

In each response we populate:

• for MESSAGE_TYPE_TRANSCRIPT: transcript and possibly is_final.

• for MESSAGE_TYPE_END_OF_SINGLE_UTTERANCE: only message_type.

Fields
message_type	MessageType Type of the result message.
transcript	string Transcript text representing the words that the user spoke. Populated if and only if message_type = MESSAGE_TYPE_TRANSCRIPT.
is_final	bool If false, the StreamingRecognitionResult represents an interim result that may change. If true, the recognizer will not return any further hypotheses about this piece of the audio. May only be populated for message_type = MESSAGE_TYPE_TRANSCRIPT.
confidence	float The Speech confidence between 0.0 and 1.0 for the current portion of audio. A higher number indicates an estimated greater likelihood that the recognized words are correct. The default of 0.0 is a sentinel value indicating that confidence was not set. This field is typically only provided if is_final is true and you should not rely on it being accurate or even set.

MessageType

Type of the response message.

Enums
MESSAGE_TYPE_UNSPECIFIED	Not specified. Should never be used.
TRANSCRIPT	Message contains a (possibly partial) transcript.
END_OF_SINGLE_UTTERANCE	Event indicates that the server has detected the end of the user's speech utterance and expects no additional speech. Therefore, the server will not process additional audio (although it may subsequently return additional results). The client should stop sending additional audio data, half-close the gRPC connection, and wait for any additional results until the server closes the gRPC connection. This message is only sent if single_utterance was set to true, and is not used otherwise.

SynthesizeSpeechConfig

Configuration of how speech should be synthesized.

Fields
speaking_rate	double 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.
pitch	double 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.
volume_gain_db	double 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.
effects_profile_id[]	string 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.
voice	VoiceSelectionParams Optional. The desired voice of the synthesized audio.

update_mask	FieldMask Optional. The mask to control which fields get updated.

UpdateIntentRequest

The request message for Intents.UpdateIntent.

Fields
intent	Intent Required. The intent to update. Authorization requires the following Google IAM permission on the specified resource intent: dialogflow.intents.update

UpdateKnowledgeBaseRequest

Request message for KnowledgeBases.UpdateKnowledgeBase.

Fields
knowledge_base	KnowledgeBase Required. The knowledge base to update.

UpdateSessionEntityTypeRequest

The request message for SessionEntityTypes.UpdateSessionEntityType.

Fields
session_entity_type	SessionEntityType Required. The entity type to update. Format: projects/<Project ID>/agent/sessions/<Session ID>/entityTypes/<Entity Type Display Name> or projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>/entityTypes/<Entity Type Display Name>.

update_mask	FieldMask Optional. The mask to control which fields get updated.

VoiceSelectionParams

Description of which voice to use for speech synthesis.

Fields
name	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 gender.
ssml_gender	SsmlVoiceGender 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 should substitute a voice with a different gender rather than failing the request.
