Future<TranslateTextResponse> translateText({ required String sourceLanguageCode, required String targetLanguageCode, required String text, List<String>? terminologyNames, })

Translates input text from the source language to the target language. For a list of available languages and language codes, see what-is-languages.

May throw InvalidRequestException. May throw TextSizeLimitExceededException. May throw TooManyRequestsException. May throw UnsupportedLanguagePairException.

Parameter sourceLanguageCode : The language code for the language of the source text. The language must be a language supported by Amazon Translate. For a list of language codes, see what-is-languages.

To have Amazon Translate determine the source language of your text, you can specify auto in the SourceLanguageCode field. If you specify auto, Amazon Translate will call Amazon Comprehend to determine the source language.

Parameter targetLanguageCode : The language code requested for the language of the target text. The language must be a language supported by Amazon Translate.

Parameter text : The text to translate. The text string can be a maximum of 5,000 bytes long. Depending on your character set, this may be fewer than 5,000 characters.

Parameter terminologyNames : The name of the terminology list file to be used in the TranslateText request. You can use 1 terminology list at most in a TranslateText request. Terminology lists can contain a maximum of 256 terms.
