LanguageDetector: expectedInputLanguages property

{{APIRef("Translator and Language Detector APIs")}}{{SeeCompatTable}}{{securecontext_header}}

The expectedInputLanguages read-only property of the {{domxref("LanguageDetector")}} interface returns the expected languages to be detected in the input text. Specifying expected input languages helps improve the accuracy of the language detection.

A LanguageDetector instance's expectedInputLanguages are set when creating it via a {{domxref("LanguageDetector.create_static", "create()")}} call.

Value

An array of strings specifying the expected input languages. These will be valid {{glossary("BCP 47 language tag", "BCP 47 language tags")}}.

Examples

const detector = await LanguageDetector.create({
  expectedInputLanguages: ["en-US", "zh"],
});

// Logs ["en-US", "zh"]
console.log(detector.expectedInputLanguages);
