カスタム語彙を作成するには

次の create-vocabulary 例は、カスタム語彙を作成します。カスタム語彙を作成するには、より正確に書き起こすべき用語のすべてを含むテキストファイルを作成しておく必要があります。vocabulary-file-uri として、そのテキストファイルの Amazon Simple Storage Service (Amazon S3) URI を指定します。language-code として、カスタム語彙の言語に対応する言語コードを指定します。vocabulary-name として、カスタムボキャブラリーに付ける名前を指定します。

aws transcribe create-vocabulary \
    --language-code language-code \
    --vocabulary-name cli-vocab-example \
    --vocabulary-file-uri s3://amzn-s3-demo-bucket/Amazon-S3-prefix/the-text-file-for-the-custom-vocabulary.txt

出力:

{
    "VocabularyName": "cli-vocab-example",
    "LanguageCode": "language-code",
    "VocabularyState": "PENDING"
}
