Return type

Returns

A list of dictionaries for each queried value. Each dictionary typically contains three keys (though not all will be present in all cases)

  • detectedSourceLanguage: The detected language (as an ISO 639-1 language code) of the text.

  • translatedText: The translation of the text into the target language.

  • input: The corresponding input value.

  • model: The model used to translate the text.

If only a single value is passed, then only a single dictionary will be returned.

Raises

ValueError if the number of values and translations differ.
