languageOptions

Specify two or more language codes that represent the languages you think may be present in your media; including more than five is not recommended. If you're unsure what languages are present, do not include this parameter.

Including language options can improve the accuracy of language identification.

If you include LanguageOptions, you must also include IdentifyLanguage.

You can only include one language dialect per language. For example, you cannot include en-US and en-AU.
