CreateVocabularyFilter - Transcribe

CreateVocabularyFilter

Creates a new custom vocabulary filter.

You can use custom vocabulary filters to mask, delete, or flag specific words from your transcript. Custom vocabulary filters are commonly used to mask profanity in transcripts.

Each language has a character set that contains all allowed characters for that specific language. If you use unsupported characters, your custom vocabulary filter request fails. Refer to Character Sets for Custom Vocabularies to get the character set for your language.

For more information, see Vocabulary filtering.

Request Syntax

{ "LanguageCode": "string", "Tags": [ { "Key": "string", "Value": "string" } ], "VocabularyFilterFileUri": "string", "VocabularyFilterName": "string", "Words": [ "string" ] }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

LanguageCode

The language code that represents the language of the entries in your vocabulary filter. Each custom vocabulary filter must contain terms in only one language.

A custom vocabulary filter can only be used to transcribe files in the same language as the filter. For example, if you create a custom vocabulary filter using US English (en-US), you can only apply this filter to files that contain English audio.

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

The other option for creating your vocabulary filter is to save your entries in a text file and upload them to an Amazon S3 bucket, then specify the location of your file using the VocabularyFilterFileUri parameter.

Note that if you include Words in your request, you cannot use VocabularyFilterFileUri; you must choose one or the other.

Each language has a character set that contains all allowed characters for that specific language. If you use unsupported characters, your custom vocabulary filter request fails. Refer to Character Sets for Custom Vocabularies to get the character set for your language.
