FineReader Engine API の言語関連オブジェクト — TextLanguage、BaseLanguage、PredefinedLanguages、Dictionary、および認識言語と辞書に関連するオブジェクト。 テキストの認識言語は、[TextLanguage](/ja/fine-reader/engine/api-reference/language-related-objects/textlanguage) オブジェクトで表されます。認識時には、テキストは単語に分割され、各単語には 1 つまたは複数の認識言語が対応します。単語内の各文字には 1 つの認識言語が割り当てられます。この認識言語は、[BaseLanguage](/ja/fine-reader/engine/api-reference/language-related-objects/baselanguage) オブジェクトで表されます。 また、このオブジェクト グループには、定義済み言語のコレクションも含まれます。これは、ABBYY FineReader Engine が既定でサポートしている認識言語です。これらは [PredefinedLanguages](/ja/fine-reader/engine/api-reference/language-related-objects/predefinedlanguages) オブジェクトで表されます。個々の定義済み言語は [PredefinedLanguage](/ja/fine-reader/engine/api-reference/language-related-objects/predefinedlanguage) オブジェクトで表され、対応する TextLanguage オブジェクトにアクセスできます。 このセクションには、次の言語関連オブジェクトの説明があります。 *
