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.

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 10 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.

Fields
parent

string

Required. The project of this agent. Format: projects/<Project ID>.

display_name

string

Required. The name of this agent.

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 is 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.

Format of the session name: projects/<Project ID>/agent/sessions/<Session ID>, or projects/<Project ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session ID>. Note: Environments and users are under construction and will be available soon. If Environment ID is not specified, we assume default 'draft' environment. If User ID is not specified, we are using "-". It’s up to the API caller to choose an appropriate Session ID and User Id. They can be a random numbers or some type of user and session identifiers (preferably hashed). The length of the Session ID and User ID must not exceed 36 characters.

Authorization requires the following Google IAM permission on the specified resource session:

  2. a conversational query in the form of text, or

  3. an event that specifies which intent to trigger.

single_utterance

bool

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. This setting is ignored when query_input is a piece of text or an event.

input_audio

bytes

Optional. The input audio content to be recognized. Must be sent if query_input was set to a streaming input audio config. The complete audio over all streaming messages must not exceed 1 minute.

StreamingDetectIntentResponse

The top-level message returned from the StreamingDetectIntent method.

Multiple response messages can be returned in order:

  1. If the input was set to streaming audio, the first one or more messages contain recognition_result. Each recognition_result represents a more complete transcript of what the user said. The last recognition_result has is_final set to true.

  2. The next message contains response_id, query_result and optionally webhook_status if a WebHook was called.

Fields
response_id

string

The unique identifier of the response. It can be used to locate a response in the training example set or for reporting issues.

recognition_result

StreamingRecognitionResult

The result of speech recognition.

query_result

QueryResult

The result of the conversational query or event processing.

webhook_status

Status

Specifies the status of the webhook request.

StreamingRecognitionResult

Contains a speech recognition result corresponding to a portion of the audio that is currently being processed or an indication that this is the end of the single requested utterance.

Example:

  1. transcript: "tube"

  2. transcript: "to be a"

  3. transcript: "to be"

  4. transcript: "to be or not to be" is_final: true

  5. transcript: " that's"

  6. transcript: " that is"

  7. recognition_event_type: RECOGNITION_EVENT_END_OF_SINGLE_UTTERANCE

  8. transcript: " that is the question" is_final: true

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 event_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 event_type = RECOGNITION_EVENT_TRANSCRIPT.

is_final

bool

The default of 0.0 is a sentinel value indicating confidence was not set. 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 event_type = RECOGNITION_EVENT_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.
