Amazon Transcribe examples using AWS CLI

The following code examples show you how to perform actions and implement common scenarios by using the AWS Command Line Interface with Amazon Transcribe.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use create-language-model.

AWS CLI

Example 1: To create a custom language model using both training and tuning data.

The following create-language-model example creates a custom language model. You can use a custom language model to improve transcription performance for domains such as legal, hospitality, finance, and insurance. For language-code, enter a valid language code. For base-model-name, specify a base model that is best suited for the sample rate of the audio that you want to transcribe with your custom language model. For model-name, specify the name that you want to call the custom language model.

aws transcribe create-language-model \
    --language-code language-code \
    --base-model-name base-model-name \
    --model-name cli-clm-example \
    --input-data-config S3Uri="s3://DOC-EXAMPLE-BUCKET/Amazon-S3-Prefix-for-training-data",TuningDataS3Uri="s3://DOC-EXAMPLE-BUCKET/Amazon-S3-Prefix-for-tuning-data",DataAccessRoleArn="arn:aws:iam::AWS-account-number:role/IAM-role-with-permissions-to-create-a-custom-language-model"

Output:

{
    "LanguageCode": "language-code",
    "BaseModelName": "base-model-name",
    "ModelName": "cli-clm-example",
    "InputDataConfig": {
        "S3Uri": "s3://DOC-EXAMPLE-BUCKET/Amazon-S3-Prefix/",

    },
    "ModelStatus": "IN_PROGRESS"
}

For more information, see Improving Domain-Specific Transcription Accuracy with Custom Language Models in the Amazon Transcribe Developer Guide.

Example 2: To create a custom language model using only training data.

The following create-language-model example transcribes your audio file. You can use a custom language model to improve transcription performance for domains such as legal, hospitality, finance, and insurance. For language-code, enter a valid language code. For base-model-name, specify a base model that is best suited for the sample rate of the audio that you want to transcribe with your custom language model. For model-name, specify the name that you want to call the custom language model.

aws transcribe create-language-model \
    --language-code en-US \
    --base-model-name base-model-name \
    --model-name cli-clm-example \
    --input-data-config S3Uri="s3://DOC-EXAMPLE-BUCKET/Amazon-S3-Prefix-For-Training-Data",DataAccessRoleArn="arn:aws:iam::AWS-account-number:role/IAM-role-with-permissions-to-create-a-custom-language-model"

The following code example shows how to use list-medical-vocabularies.

AWS CLI

To list your medical custom vocabularies

The following list-medical-vocabularies example lists the medical custom vocabularies associated with your AWS account and Region. To get more information about a particular transcription job, copy the value of a MedicalTranscriptionJobName parameter in the transcription output, and specify that value for the MedicalTranscriptionJobName option of the get-medical-transcription-job command. To see more of your transcription jobs, copy the value of the NextToken parameter, run the list-medical-transcription-jobs command again, and specify that value in the --next-token option.
