Response Structure

• (dict) --

  • TranscriptionJob (dict) --

    An object that contains the results of the transcription job.

    • TranscriptionJobName (string) --

      The name of the transcription job.

    • TranscriptionJobStatus (string) --

      The status of the transcription job.

    • LanguageCode (string) --

      The language code for the input speech.

    • MediaSampleRateHertz (integer) --

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

    • MediaFormat (string) --

      The format of the input media file.

    • Media (dict) --

      An object that describes the input media for the transcription job.

      • MediaFileUri (string) --

        The S3 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:

        https://<aws-region>.amazonaws.com/<bucket-name>/<keyprefix>/<objectkey>

        For example:

        https://s3-us-east-1.amazonaws.com/examplebucket/example.mp4

        https://s3-us-east-1.amazonaws.com/examplebucket/mediadocs/example.mp4

        For more information about S3 object names, see Object Keys in the Amazon S3 Developer Guide .

    • Transcript (dict) --

      An object that describes the output of the transcription job.

      • TranscriptFileUri (string) --

        The location where the transcription is stored.

        Use this URI to access the transcription. If you specified an S3 bucket in the OutputBucketName field when you created the job, this is the URI of that bucket. If you chose to store the transcription in Amazon Transcribe, this is a shareable URL that provides secure access to that location.

    • CreationTime (datetime) --

      A timestamp that shows when the job was created.

    • CompletionTime (datetime) --

      A timestamp that shows when the job was completed.

    • FailureReason (string) --

      If the TranscriptionJobStatus field is FAILED , this field contains information about why the job failed.

    • Settings (dict) --

      Optional settings for the transcription job. Use these settings to turn on speaker recognition, to set the maximum number of speakers that should be identified and to specify a custom vocabulary to use when processing the transcription job.

      • VocabularyName (string) --

        The name of a vocabulary to use when processing the transcription job.

      • ShowSpeakerLabels (boolean) --

        Determines whether the transcription job uses speaker recognition to identify different speakers in the input audio. Speaker recognition labels individual speakers in the audio file. If you set the ShowSpeakerLabels field to true, you must also set the maximum number of speaker labels MaxSpeakerLabels field.

        You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException .

      • MaxSpeakerLabels (integer) --

        The maximum number of speakers to identify in the input audio. If there are more speakers in the audio than this 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) --

        Instructs Amazon Transcribe to process each audio channel separately and then merge the transcription output of each channel into a single transcription.

        Amazon Transcribe also produces a transcription of each item detected on an audio channel, including the start time and end time of the item and alternative transcriptions of the item including the confidence that Amazon Transcribe has in the transcription.

        You can't set both ShowSpeakerLabels and ChannelIdentification in the same request. If you set both, your request returns a BadRequestException .

{'Settings': {'ChannelIdentification': 'boolean'}}

[REQUIRED]

The format of the input media file.

type Media

dict

param Media

• MediaFileUri (string) --

  The S3 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:

  https://<aws-region>.amazonaws.com/<bucket-name>/<keyprefix>/<objectkey>

type OutputBucketName

string

param OutputBucketName

The location where the transcription is stored.

If you set the OutputBucketName , Amazon Transcribe puts the transcription in the specified S3 bucket. When you call the GetTranscriptionJob operation, the operation returns this location in the TranscriptFileUri field. 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 .

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.
