Language and region support for the Text Analytics API

This article explains which languages are supported for each operation: sentiment analysis, key phrase extraction, and language detection.

Language Detection

The Text Analytics API can detect up to 120 different 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.

Sentiment Analysis, Key Phrase Extraction, and Entity Recognition

For sentiment analysis, key phrase extraction, and entity recognition, the list of supported languages is more selective as the analyzers are refined to accommodate the linguistic rules of additional languages.

Language list and status

Language support is initially rolled out in preview, graduating to generally available (GA) status, independently of each other and of the Text Analytics service overall. It's possible for languages to remain in preview, even while Text Analytics API transitions to generally available.
