start-transcription-job

Description

Transcribes the audio from a media file and applies any additional Request Parameters you choose to include in your request.

To make a StartTranscriptionJob request, you must first upload your media file into an Amazon S3 bucket; you can then specify the Amazon S3 location of the file using the Media parameter.

You must include the following parameters in your StartTranscriptionJob request:

  • region : The Amazon Web Services Region where you are making your request. For a list of Amazon Web Services Regions supported with Amazon Transcribe, refer to Amazon Transcribe endpoints and quotas .

  • TranscriptionJobName : A custom name you create for your transcription job that is unique within your Amazon Web Services account.

  • Media (MediaFileUri ): The Amazon S3 location of your media file.

  • One of LanguageCode , IdentifyLanguage , or IdentifyMultipleLanguages : If you know the language of your media file, specify it using the LanguageCode parameter; you can find all valid language codes in the Supported languages table. If you don’t know the languages spoken in your media, use either IdentifyLanguage or IdentifyMultipleLanguages and let Amazon Transcribe identify the languages for you.

Options

--transcription-job-name (string)

A unique name, chosen by you, for your transcription job. The name you specify is also used as the default name of your transcription output file. If you want to specify a different name for your transcription output, use the OutputKey parameter.

This name is case sensitive, cannot contain spaces, and must be unique within an Amazon Web Services account. If you try to create a new job with the same name as an existing job, you get a ConflictException error.

--language-code (string)

The language code that represents the language spoken in the input media file.

If you’re unsure of the language spoken in your media file, consider using IdentifyLanguage or IdentifyMultipleLanguages to enable automatic language identification.

Note that you must include one of LanguageCode , IdentifyLanguage , or IdentifyMultipleLanguages in your request. If you include more than one of these parameters, your transcription job fails.

For a list of supported languages and their associated language codes, refer to the Supported languages table.

Note

To transcribe speech in Modern Standard Arabic (ar-SA ), your media file must be encoded at a sample rate of 16,000 Hz or higher.

--media-sample-rate-hertz (integer)

The sample rate, in Hertz, of the audio track in your input media file.

If you don’t specify the media sample rate, Amazon Transcribe determines it for you. If you specify the sample rate, it must match the rate detected by Amazon Transcribe; if there’s a mismatch between the value you specify and the value detected, your job fails. Therefore, in most cases, it’s advised to omit MediaSampleRateHertz and let Amazon Transcribe determine the sample rate.

--media-format (string)

Specify the format of your input media file.

Possible values:

  • mp3

  • mp4

  • wav

  • flac

  • ogg

  • amr

  • webm

--media (structure)

Describes the Amazon S3 location of the media file you want to use in your request.

MediaFileUri -> (string)

The Amazon S3 location of the media file you want to transcribe. For example:

  • s3://DOC-EXAMPLE-BUCKET/my-media-file.flac

  • s3://DOC-EXAMPLE-BUCKET/media-files/my-media-file.flac

Note that the Amazon S3 bucket that contains your input media must be located in the same Amazon Web Services Region where you’re making your transcription request.

RedactedMediaFileUri -> (string)

The Amazon S3 location of the media file you want to redact. For example:

  • s3://DOC-EXAMPLE-BUCKET/my-media-file.flac

  • s3://DOC-EXAMPLE-BUCKET/media-files/my-media-file.flac

Note that the Amazon S3 bucket that contains your input media must be located in the same Amazon Web Services Region where you’re making your transcription request.

Warning

RedactedMediaFileUri is only supported for Call Analytics (StartCallAnalyticsJob ) transcription requests.

Shorthand Syntax:

MediaFileUri=string,RedactedMediaFileUri=string

JSON Syntax:

{
  "MediaFileUri": "string",
  "RedactedMediaFileUri": "string"
}

--output-bucket-name (string)

The name of the Amazon S3 bucket where you want your transcription output stored. Do not include the S3:// prefix of the specified bucket.

If you want your output to go to a sub-folder of this bucket, specify it using the OutputKey parameter; OutputBucketName only accepts the name of a bucket.

For example, if you want your output stored in S3://DOC-EXAMPLE-BUCKET , set OutputBucketName to DOC-EXAMPLE-BUCKET . However, if you want your output stored in S3://DOC-EXAMPLE-BUCKET/test-files/ , set OutputBucketName to DOC-EXAMPLE-BUCKET and OutputKey to test-files/ .

Note that Amazon Transcribe must have permission to use the specified location. You can change Amazon S3 permissions using the Amazon Web Services Management Console . See also Permissions Required for IAM User Roles .

If you don’t specify OutputBucketName , your transcript is placed in a service-managed Amazon S3 bucket and you are provided with a URI to access your transcript.

--output-key (string)

Use in combination with OutputBucketName to specify the output location of your transcript and, optionally, a unique name for your output file. The default name for your transcription output is the same as the name you specified for your transcription job (TranscriptionJobName ).

Here are some examples of how you can use OutputKey :

  • If you specify ‘DOC-EXAMPLE-BUCKET’ as the OutputBucketName and ‘my-transcript.json’ as the OutputKey , your transcription output path is s3://DOC-EXAMPLE-BUCKET/my-transcript.json .

  • If you specify ‘my-first-transcription’ as the TranscriptionJobName , ‘DOC-EXAMPLE-BUCKET’ as the OutputBucketName , and ‘my-transcript’ as the OutputKey , your transcription output path is s3://DOC-EXAMPLE-BUCKET/my-transcript/my-first-transcription.json .

  • If you specify ‘DOC-EXAMPLE-BUCKET’ as the OutputBucketName and ‘test-files/my-transcript.json’ as the OutputKey , your transcription output path is s3://DOC-EXAMPLE-BUCKET/test-files/my-transcript.json .

  • If you specify ‘my-first-transcription’ as the TranscriptionJobName , ‘DOC-EXAMPLE-BUCKET’ as the OutputBucketName , and ‘test-files/my-transcript’ as the OutputKey , your transcription output path is s3://DOC-EXAMPLE-BUCKET/test-files/my-transcript/my-first-transcription.json .

If you specify the name of an Amazon S3 bucket sub-folder that doesn’t exist, one is created for you.

--output-encryption-kms-key-id (string)

The KMS key you want to use to encrypt your transcription output.

If using a key located in the current Amazon Web Services account, you can specify your KMS key in one of four ways:

  • Use the KMS key ID itself. For example, 1234abcd-12ab-34cd-56ef-1234567890ab .

  • Use an alias for the KMS key ID. For example, alias/ExampleAlias .

  • Use the Amazon Resource Name (ARN) for the KMS key ID. For example, arn:aws:kms:region:account-ID:key/1234abcd-12ab-34cd-56ef-1234567890ab .

  • Use the ARN for the KMS key alias. For example, arn:aws:kms:region:account-ID:alias/ExampleAlias .

If using a key located in a different Amazon Web Services account than the current Amazon Web Services account, you can specify your KMS key in one of two ways:

  • Use the ARN for the KMS key ID. For example, arn:aws:kms:region:account-ID:key/1234abcd-12ab-34cd-56ef-1234567890ab .

  • Use the ARN for the KMS key alias. For example, arn:aws:kms:region:account-ID:alias/ExampleAlias .

If you don’t specify an encryption key, your output 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 using the OutputLocation parameter.

Note that the user making the request must have permission to use the specified KMS key.

--kms-encryption-context (map)

A map of plain text, non-secret key:value pairs, known as encryption context pairs, that provide an added layer of security for your data. For more information, see KMS encryption context and Asymmetric keys in KMS .

--settings (structure)

Specify additional optional settings in your request, including channel identification, alternative transcriptions, speaker labeling; allows you to apply custom vocabularies and vocabulary filters.

If you want to include a custom vocabulary or a custom vocabulary filter (or both) with your request but do not want to use automatic language identification, use Settings with the VocabularyName or VocabularyFilterName (or both) sub-parameter.

If you’re using automatic language identification with your request and want to include a custom language model, a custom vocabulary, or a custom vocabulary filter, use instead the parameter with the LanguageModelName , VocabularyName or VocabularyFilterName sub-parameters.

VocabularyName -> (string)

The name of the custom vocabulary you want to use in your transcription job request. This name is case sensitive, cannot contain spaces, and must be unique within an Amazon Web Services account.

ShowSpeakerLabels -> (boolean)

Enables speaker identification (diarization) in your transcription output. Speaker identification labels the speech from individual speakers in your media file.

If you enable ShowSpeakerLabels in your request, you must also include MaxSpeakerLabels .

You can’t include both ShowSpeakerLabels and ChannelIdentification in the same request. Including both parameters returns a BadRequestException .

For more information, see Identifying speakers (diarization) .

MaxSpeakerLabels -> (integer)

Specify the maximum number of speakers you want to identify in your media.

Note that if your media contains more speakers than the specified number, multiple speakers will be identified as a single speaker.

If you specify the MaxSpeakerLabels field, you must set the ShowSpeakerLabels field to true.

ChannelIdentification -> (boolean)

Enables channel identification in multi-channel audio.

Channel identification transcribes the audio on each channel independently, then appends the output for each channel into one transcript.

You can’t include both ShowSpeakerLabels and ChannelIdentification in the same request. Including both parameters returns a BadRequestException .

For more information, see Transcribing multi-channel audio .

ShowAlternatives -> (boolean)

To include alternative transcriptions within your transcription output, include ShowAlternatives in your transcription request.

If you have multi-channel audio and do not enable channel identification, your audio is transcribed in a continuous manner and your transcript does not separate the speech by channel.

If you include ShowAlternatives , you must also include MaxAlternatives , which is the maximum number of alternative transcriptions you want Amazon Transcribe to generate.

For more information, see Alternative transcriptions .

MaxAlternatives -> (integer)

Indicate the maximum number of alternative transcriptions you want Amazon Transcribe to include in your transcript.

If you select a number greater than the number of alternative transcriptions generated by Amazon Transcribe, only the actual number of alternative transcriptions are included.

If you include MaxAlternatives in your request, you must also include ShowAlternatives with a value of true .

For more information, see Alternative transcriptions .

VocabularyFilterName -> (string)

The name of the custom vocabulary filter you want to use in your transcription job request. This name is case sensitive, cannot contain spaces, and must be unique within an Amazon Web Services account.

Note that if you include VocabularyFilterName in your request, you must also include VocabularyFilterMethod .

VocabularyFilterMethod -> (string)

Specify how you want your vocabulary filter applied to your transcript.

To replace words with *** , choose mask .

To delete words, choose remove .

To flag words without changing them, choose tag .

  "VocabularyFilterName": "string",
  "VocabularyFilterMethod": "remove"|"mask"|"tag"
}

--model-settings (structure)

Specify the custom language model you want to include with your transcription job. If you include ModelSettings in your request, you must include the LanguageModelName sub-parameter.

For more information, see Custom language models .

LanguageModelName -> (string)

The name of the custom language model you want to use when processing your transcription job. Note that language model names are case sensitive.

The language of the specified language model must match the language code you specify in your transcription request. If the languages don’t match, the language model isn’t applied. There are no errors or warnings associated with a language mismatch.

Shorthand Syntax:

LanguageModelName=string

JSON Syntax:

{
  "LanguageModelName": "string"
}

--job-execution-settings (structure)

Allows you to control how your transcription job is processed. Currently, the only JobExecutionSettings modification you can choose is enabling job queueing using the AllowDeferredExecution sub-parameter.

If you include JobExecutionSettings in your request, you must also include the sub-parameters: AllowDeferredExecution and DataAccessRoleArn .

AllowDeferredExecution -> (boolean)

Allows you to enable job queuing when your concurrent request limit is exceeded. When AllowDeferredExecution is set to true , transcription job requests are placed in a queue until the number of jobs falls below the concurrent request limit. If AllowDeferredExecution is set to false and the number of transcription job requests exceed the concurrent request limit, you get a LimitExceededException error.

Note that job queuing is enabled by default for Call Analytics jobs.

If you include AllowDeferredExecution in your request, you must also include DataAccessRoleArn .

DataAccessRoleArn -> (string)

The Amazon Resource Name (ARN) of an IAM role that has permissions to access the Amazon S3 bucket that contains your input files. If the role you specify doesn’t have the appropriate permissions to access the specified Amazon S3 location, your request fails.

IAM role ARNs have the format arn:partition:iam::account:role/role-name-with-path . For example: arn:aws:iam::111122223333:role/Admin . For more information, see IAM ARNs .

Note that if you include DataAccessRoleArn in your request, you must also include AllowDeferredExecution .

AllowDeferredExecution=boolean,DataAccessRoleArn=string

JSON Syntax:

{
  "AllowDeferredExecution": true|false,
  "DataAccessRoleArn": "string"
}

--content-redaction (structure)

Allows you to redact or flag specified personally identifiable information (PII) in your transcript. If you use ContentRedaction , you must also include the sub-parameters: PiiEntityTypes , RedactionOutput , and RedactionType .

RedactionType -> (string)

Specify the category of information you want to redact; PII (personally identifiable information) is the only valid value. You can use PiiEntityTypes to choose which types of PII you want to redact.

RedactionOutput -> (string)

Specify if you want only a redacted transcript, or if you want a redacted and an unredacted transcript.

When you choose redacted Amazon Transcribe creates only a redacted transcript.

When you choose redacted_and_unredacted Amazon Transcribe creates a redacted and an unredacted transcript (as two separate files).

PiiEntityTypes -> (list)

Specify which types of personally identifiable information (PII) you want to redact in your transcript. You can include as many types as you’d like, or you can select ALL .

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Value -> (string)

The second part of a key:value pair that forms a tag associated with a given resource. For example, in the tag Department:Sales , the value is ‘Sales’.

Note that you can set the value of a tag to an empty string, but you can’t set the value of a tag to null. Omitting the tag value is the same as using an empty string.

Subtitles -> (structure)

Generate subtitles for your media file with your transcription request.

Formats -> (list)

Provides the format of your subtitle files. If your request included both WebVTT (vtt ) and SubRip (srt ) formats, both formats are shown.

(string)

SubtitleFileUris -> (list)

The Amazon S3 location of your transcript. You can use this URI to access or download your subtitle file. Your subtitle file is stored in the same location as your transcript. If you specified both WebVTT and SubRip subtitle formats, two URIs are provided.

If you included OutputBucketName in your transcription job request, this is the URI of that bucket. If you also included OutputKey in your request, your output is located in the path you specified in your request.

If you didn’t include OutputBucketName in your transcription job request, your subtitle file is stored in a service-managed bucket, and TranscriptFileUri provides you with a temporary URI you can use for secure access to your subtitle file.

Note

Temporary URIs for service-managed Amazon S3 buckets are only valid for 15 minutes. If you get an AccesDenied error, you can get a new temporary URI by running a GetTranscriptionJob or ListTranscriptionJob request.

(string)

OutputStartIndex -> (integer)

Provides the start index value for your subtitle files. If you did not specify a value in your request, the default value of 0 is used.

LanguageIdSettings -> (map)

If using automatic language identification (IdentifyLanguage ) in your request and you want to apply a custom language model, a custom vocabulary, or a custom vocabulary filter, include LanguageIdSettings with the relevant sub-parameters (VocabularyName , LanguageModelName , and VocabularyFilterName ).

You can specify two or more language codes that represent the languages you think may be present in your media; including more than five is not recommended. Each language code you include can have an associated custom language model, custom vocabulary, and custom vocabulary filter. The languages you specify must match the languages of the specified custom language models, custom vocabularies, and custom vocabulary filters.

To include language options using IdentifyLanguage without including a custom language model, a custom vocabulary, or a custom vocabulary filter, use LanguageOptions instead of LanguageIdSettings . Including language options can improve the accuracy of automatic language identification.

If you want to include a custom language model with your request but do not want to use automatic language identification, use instead the parameter with the LanguageModelName sub-parameter.

If you want to include a custom vocabulary or a custom vocabulary filter (or both) with your request but do not want to use automatic language identification, use instead the parameter with the VocabularyName or VocabularyFilterName (or both) sub-parameter.
