2020/02/26 - Amazon Transcribe Service - 3 updated api methods
Changes Amazon Transcribe's Automatic Content Redaction feature enables you to automatically redact sensitive personally identifiable information (PII) from transcription results. It replaces each instance of an identified PII utterance with a [PII] tag in the transcript.
{'TranscriptionJob': {'ContentRedaction': {'RedactionOutput': 'redacted | '
'redacted_and_unredacted',
'RedactionType': 'PII'},
'Transcript': {'RedactedTranscriptFileUri': 'string'}}}
Returns information about a transcription job. To see the status of the job, check the TranscriptionJobStatus field. If the status is COMPLETED , the job is finished and you can find the results at the location specified in the TranscriptFileUri field. If you enable content redaction, the redacted transcript appears in RedactedTranscriptFileUri .

string
[REQUIRED]
The name of the job. Note that you can't use the strings "." or ".." by themselves as the job name. The name must also be unique within an AWS account.
string
[REQUIRED]
The language code for the language used in the input media file.
integer
The sample rate, in Hertz, of the audio track in the input media file.
If you do not specify the media sample rate, Amazon Transcribe determines the sample rate. If you specify the sample rate, it must match the sample rate detected by Amazon Transcribe. In most cases, you should leave the MediaSampleRateHertz field blank and let Amazon Transcribe determine the sample rate.
string
The format of the input media file.
dict
[REQUIRED]
An object that describes the input media for a transcription job.
MediaFileUri (string) --
The S3 object location of the input media file. The URI must be in the same region as the API endpoint that you are calling. The general form is:
s3://<bucket-name>/<keyprefix>/<objectkey>
For example:
s3://examplebucket/example.mp4
s3://examplebucket/mediadocs/example.mp4
For more information about S3 object names, see Object Keys in the Amazon S3 Developer Guide .
string
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.
string
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.
You can use either of the following to identify a KMS key in the current account:
KMS Key ID: "1234abcd-12ab-34cd-56ef-1234567890ab"
KMS Key Alias: "alias/ExampleAlias"
You can use either of the following to identify a KMS key in the current account or another account:
Amazon Resource Name (ARN) of a KMS Key: "arn:aws:kms:region:account ID:key/1234abcd-12ab-34cd-56ef-1234567890ab"
ARN of a KMS Key Alias: "arn:aws:kms:region:account ID:alias/ExampleAlias"
If you don't specify an encryption key, the output of the transcription job is encrypted with the default Amazon S3 key (SSE-S3).
If you specify a KMS key to encrypt your output, you must also specify an output location in the OutputBucketName parameter.
