Defining EventBridge rules Amazon Transcribe events

Using Amazon EventBridge with Amazon Transcribe

With Amazon EventBridge, you can respond to state changes in your Amazon Transcribe jobs by initiating events in other AWS services. When a transcription job changes state, EventBridge automatically sends an event to an event stream. You create rules that define the events that you want to monitor in the event stream and the action that EventBridge should take when those events occur. For example, routing the event to another service (or target), which can then take an action. You could, for example, configure a rule to route an event to an AWS Lambda function when a transcription job has completed successfully. To define EventBridge rules, refer to the following sections.

You can receive notifications for events through multiple channels, including email, AWS Chatbot chat notifications, or AWS Console Mobile Application push notifications. You can also see notifications in the Console Notifications Center. If you want to set up notifications, you can use AWS User Notifications. AWS User Notifications supports aggregation, which can reduce the number of notifications you receive during specific events.

Defining EventBridge rules

To define EventBridge rules, use the AWS Management Console. When you define a rule, use Amazon Transcribe as the service name. For an example of how to create an EventBridge rule, see Amazon EventBridge rules.

Before using EventBridge, note the following definitions:

Event–An event indicates a change in the state of one of your transcription jobs. For example, when the TranscriptionJobStatus of a job changes from IN_PROGRESS to COMPLETED.
Target–A target is another AWS service that processes an event. For example, AWS Lambda or Amazon Simple Notification Service (Amazon SNS). A target receives events in JSON format.
Rule–A rule matches incoming events that you want EventBridge to watch for and routes them to a target or targets for processing. If a rule routes an event to multiple targets, all of the targets process the event in parallel. A rule can customize the JSON sent to the target.

Amazon EventBridge events are emitted on a best-effort basis. For more information about creating and managing events in EventBridge, see Amazon EventBridge events in the Amazon EventBridge User Guide.

The following is an example of an EventBridge rule for Amazon Transcribe that's initiated when a transcription job's status changes to COMPLETED or FAILED.


{
    "source": [
        "aws.transcribe"
    ],
    "detail-type": [
        "Transcribe Job State Change"
    ],
    "detail": {
        "TranscriptionJobStatus": [
            "COMPLETED",
            "FAILED"
        ]
    }
}

The rule contains the following fields:

source–The source of the event. For Amazon Transcribe, this is always aws.transcribe.
detail-type–An identifier for the details of the event. For Amazon Transcribe, this is always Transcribe Job State Change.
detail–The new job status of the transcription job. In this example, the rule initiates an event when the job status changes to COMPLETED or FAILED.

Amazon Transcribe events

Amazon EventBridge logs several Amazon Transcribe events:

Transcription job events
Language identification events
Call Analytics events
Call Analytics post-call events
Vocabulary events

These events all contain the following shared fields:

version: The version of the event data. This value is always 0.
id: A unique identifier generated by EventBridge for the event.
detail-type: An identifier for the details of the event. For example, Transcribe Job State Change.
source: The source of the event. For Amazon Transcribe this is always aws.transcribe.
account: The AWS account ID of the account that generated the API call.
time: The date and time the event is delivered.
region: The AWS Region in which the request is made.
resources: The resources used by the API call. For Amazon Transcribe, this field is always empty.
detail: Additional details about the event.
- FailureReason: This field is present if the state or status changes to FAILED, and describes the reason for the FAILED state or status.
- Each event type has additional unique fields that are displayed under detail. These unique fields are defined in the following sections after each event example.

Transcription job events

When a job's state changes from IN_PROGRESS to COMPLETED or FAILED, Amazon Transcribe generates an event. To identify the job that changed state and initiate the event in your target, use the event's TranscriptionJobName field. An Amazon Transcribe event contains the following information. A FailureReason field is added under detail if your transcription job status is FAILED.

Note that this event applies only to the StartTranscriptionJob API operation.

TranscriptionJobStatus : The status of the transcription job. This can be COMPLETED or FAILED.

Language identification events

When you enable automatic language identification, Amazon Transcribe generates an event when the language identification state is COMPLETED or FAILED. To identify the job that changed state and initiate the event in your target, use the event's JobName field. An Amazon Transcribe event contains the following information. A FailureReason field is added under detail if your language identification status is FAILED.

Note that this event applies only to the StartTranscriptionJob API operation when the LanguageIdSettings parameter is included.
