language_hints
MutableSequence[str]
List of languages to use for OCR. In most cases, an empty
value yields the best results since it enables automatic
language detection. For languages based on the Latin
alphabet, setting language_hints is not needed. In rare
cases, when the language of the text in the image is known,
setting a hint will help get better results (although it
will be a significant hindrance if the hint is wrong).
Document processing returns an error if one or more of the
specified languages is not one of the supported languages.
