For more information about S3 object names, see Object Keys in the Amazon S3 Developer Guide .
The location where the transcription is stored.
If you set the OutputBucketName , Amazon Transcribe puts the transcript in the specified S3 bucket. When you call the GetTranscriptionJob operation, the operation returns this location in the TranscriptFileUri field. If you enable content redaction, the redacted transcript appears in RedactedTranscriptFileUri . If you enable content redaction and choose to output an unredacted transcript, that transcript's location still appears in the TranscriptFileUri . The S3 bucket must have permissions that allow Amazon Transcribe to put files in the bucket. For more information, see Permissions Required for IAM User Roles .
You can specify an AWS Key Management Service (KMS) key to encrypt the output of your transcription using the OutputEncryptionKMSKeyId parameter. If you don't specify a KMS key, Amazon Transcribe uses the default Amazon S3 key for server-side encryption of transcripts that are placed in your S3 bucket.
If you don't set the OutputBucketName , Amazon Transcribe generates a pre-signed URL, a shareable URL that provides secure access to your transcription, and returns it in the TranscriptFileUri field. Use this URL to download the transcription.
The Amazon Resource Name (ARN) of the AWS Key Management Service (KMS) key used to encrypt the output of the transcription job. The user calling the StartTranscriptionJob operation must have permission to use the specified KMS key.

If the field is false, Amazon Transcribe returns a LimitExceededException exception.
If you specify the AllowDeferredExecution field, you must specify the DataAccessRoleArn field.
The Amazon Resource Name (ARN) of a role that has access to the S3 bucket that contains the input files. Amazon Transcribe will assume this role to read queued media files. If you have specified an output S3 bucket for the transcription results, this role should have access to the output bucket as well.
If you specify the AllowDeferredExecution field, you must specify the DataAccessRoleArn field.
An object that contains the request parameters for content redaction.
Request parameter that defines the entities to be redacted. The only accepted value is PII .
Request parameter where you choose whether to output only the redacted transcript or generate an additional unredacted transcript.
When you choose redacted Amazon Transcribe outputs a JSON file with only the redacted transcript and related information.
When you choose redacted_and_unredacted Amazon Transcribe outputs a JSON file with the unredacted transcript and related information in addition to the JSON file with the redacted transcript.
