REST Resource: projects.agent.environments

Resource: Environment

You can create multiple versions of your agent and publish them to separate environments.

When you edit an agent, you are editing the draft agent. At any point, you can save the draft agent as an agent version, which is an immutable snapshot of your agent.

When you save the draft agent, it is published to the default environment. When you create agent versions, you can publish them to custom environments. You can create a variety of custom environments for:

  • testing
  • development
  • production
  • etc.

For more information, see the versions and environments guide.

Fields
name

string

Output only. The unique identifier of this agent environment. Supported formats:

  • projects/<Project ID>/agent/environments/<Environment ID>
  • projects/<Project ID>/locations/<Location ID>/agent/environments/<Environment ID>

The environment ID for the default environment is -.
description

string

Optional. The developer-provided description for this environment. The maximum length is 500 characters. If exceeded, the request is rejected.
agentVersion

string

Optional. The agent version loaded into this environment. Supported formats:

  • projects/<Project ID>/agent/versions/<Version ID>
  • projects/<Project ID>/locations/<Location ID>/agent/versions/<Version ID>
state

enum (State)

Output only. The state of this environment. This field is read-only, i.e., it cannot be set by create and update methods.
updateTime

string (Timestamp format)

Output only. The last update time of this environment. This field is read-only, i.e., it cannot be set by create and update methods.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
textToSpeechSettings

object (TextToSpeechSettings)

Optional. Text to speech settings for this environment.
fulfillment

object (Fulfillment)

Optional. The fulfillment settings to use for this environment.

State

Represents an environment state. When an environment is pointed to a new agent version, the environment is temporarily set to the LOADING state. During that time, the environment keeps on serving the previous version of the agent. After the new agent version is done loading, the environment is set back to the RUNNING state.

Enums
STATE_UNSPECIFIED Not specified. This value is not used.
STOPPED Stopped.
LOADING Loading.
RUNNING Running.

TextToSpeechSettings

Instructs the speech synthesizer on how to generate the output audio content.

JSON representation 
{
  "enableTextToSpeech": boolean,
  "outputAudioEncoding": enum (OutputAudioEncoding),
  "sampleRateHertz": integer,
  "synthesizeSpeechConfigs": {
    string: {
      object (SynthesizeSpeechConfig)
    },
    ...
  }
}
Fields
enableTextToSpeech

boolean

Optional. Indicates whether text to speech is enabled. Even when this field is false, other settings in this proto are still retained.
outputAudioEncoding

enum (OutputAudioEncoding)

Required. Audio encoding of the synthesized audio content.
sampleRateHertz

integer

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).
synthesizeSpeechConfigs

map (key: string, value: object (SynthesizeSpeechConfig))

Optional. Configuration of how speech should be synthesized, mapping from language (https://cloud.google.com/dialogflow/docs/reference/language) to SynthesizeSpeechConfig.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

OutputAudioEncoding

Audio encoding of the output audio format in Text-To-Speech.

Enums
OUTPUT_AUDIO_ENCODING_UNSPECIFIED Not specified.
OUTPUT_AUDIO_ENCODING_LINEAR_16 Uncompressed 16-bit signed little-endian samples (Linear PCM). Audio content returned as LINEAR16 also contains a WAV header.
OUTPUT_AUDIO_ENCODING_MP3 MP3 audio at 32kbps.
OUTPUT_AUDIO_ENCODING_MP3_64_KBPS MP3 audio at 64kbps.
OUTPUT_AUDIO_ENCODING_OGG_OPUS Opus encoded audio wrapped in an ogg container. The result will be a file which can be played natively on Android, and in browsers (at least Chrome and Firefox). The quality of the encoding is considerably higher than MP3 while using approximately the same bitrate.
OUTPUT_AUDIO_ENCODING_MULAW 8-bit samples that compand 14-bit audio samples using G.711 PCMU/mu-law.
OUTPUT_AUDIO_ENCODING_ALAW 8-bit samples that compand 13-bit audio samples using G.711 PCMU/a-law.

Fulfillment

By default, your agent responds to a matched intent with a static response. As an alternative, you can provide a more dynamic response by using fulfillment. When you enable fulfillment for an intent, Dialogflow responds to that intent by calling a service that you define. For example, if an end-user wants to schedule a haircut on Friday, your service can check your database and respond to the end-user with availability information for Friday.

For more information, see the fulfillment guide.
