Question

You are building an Azure AI service that ingests customer support emails from a global audience. Each email may contain text in an unknown language, and some emails mix two languages in the same message. Before summarizing each email with a language model, you need to reliably determine the dominant language of every message so you can route it to the correct regional team. You want the most accurate, purpose-built approach with minimal custom logic. What should you use?

Accepted Answer

Call the Azure AI Translator Detect function, which returns detected languages with confidence scores and identifies the dominant language in mixed-language text.

Answer

Send each email to a text-to-speech endpoint and infer the language from the generated audio voice profile.

Answer

Hardcode a set of regex patterns for common language keywords and choose the language with the most matches.

Answer

Use the Translator Translate function with an empty target language so it echoes back only the source language name.
