NER v3 currently only supports English and Spanish languages. If you call NER v3 with a different language, the API will return v2.1 results, provided the language is supported in version 2.1.
v2.1 only returns the full set of available entities for the English, Chinese-Simplified, French, German, and Spanish languages. The "Person", "Location" and "Organization" entities are returned for the other supported languages.

The Text Analytics API can detect a wide range of languages, variants, dialects, and some regional/cultural languages. Language Detection returns the "script" of a language. For instance, for the phrase "I have a dog" it will return en instead of en-US. The only special case is Chinese, where the language detection capability will return zh_CHS or zh_CHT if it can determine the script given the text provided. In situations where a specific script cannot be identified for a Chinese document, it will return simply zh.
We don't publish the exact list of languages for this feature, but it can detect a wide range of languages, variants, dialects, and some regional/cultural languages.
If you have content expressed in a less frequently used language, you can try Language Detection to see if it returns a code. The response for languages that cannot be detected is unknown.
