    /// <summary>
    /// Create a custom vocabulary using a list of phrases. Custom vocabularies
    /// improve transcription accuracy for one or more specific words.
    /// </summary>
    /// <param name="languageCode">The language code of the vocabulary.</param>

            });
        return response.VocabularyState;
    }

CLI

AWS CLI

创建自定义词汇表

以下 create-vocabulary 示例创建一个自定义词汇表。要创建自定义词汇表，您必须创建一个文本文件，其中包含要更准确地进行转录的所有术语。对于 vocabulary-file-uri，请指定该文本文件的亚马逊简单存储服务 (Amazon S3) Service URI。对于 language-code，指定与自定义词汇表的语言对应的语言代码。对于 vocabulary-name，指定所需的自定义词汇表名称。

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

输出：

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