An array of strings specifying the expected languages of any provided context strings (either the Summarizer.sharedContext, or a context specified during a summarize() or summarizeStreaming() call).
The strings should be valid BCP 47 language tags (as specified in RFC 5646).
const summarizer = await Summarizer.create({
expectedContextLanguages: ["en-US", "fr"],
// ...
});
// Logs "en-US"
console.log(summarizer.expectedContextLanguages[0]);
