	// If you do not specify the media sample rate, Amazon Transcribe determines

	// If you set the OutputBucketName, Amazon Transcribe puts the transcript in

	// 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

	// 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.

	//
	// You can use either of the following to identify a KMS key in the current
	// account:
	//
	//    * KMS Key ID: "1234abcd-12ab-34cd-56ef-1234567890ab"

	//
	// If you don't specify an encryption key, the output of the transcription job
	// is encrypted with the default Amazon S3 key (SSE-S3).
