Language support
Natural Language Understanding supports a variety of languages depending on which features you analyze. Currently, English is the only language that is supported across all features. The rest of the languages have limited support. To jump to the
list of features that are compatible with a language, click the language in the following list.
Language support might be different if you are a IBM Cloud® Dedicated customer. If you are using IBM Cloud® Dedicated, check with your IBM salesperson to confirm which languages are supported in your environment.
