The language of the input text for the request: Arabic, English, Japanese, Korean, or Spanish. Regional variants are treated as their parent language; for example, en-US is interpreted as en. The effect of the Content-Language parameter depends on the Content-Type parameter. When Content-Type is text/plain or text/html, Content-Language is the only way to specify the language. When Content-Type is application/json, Content-Language overrides a language specified with the language parameter of a ContentItem object, and content items that specify a different language are ignored; omit this parameter to base the language on the specification of the content items. You can specify any combination of languages for Content-Language and Accept-Language.
