For a social media messaging app, you need real-time language identification on short text messages. The Azure AI Translator service provides a dedicated Detect API that returns the language and a confidence score for each input text, designed for low-latency scenarios such as chat and in-app communication. This aligns directly with “identify in real time the language used in messages.” Microsoft Azure +2
Why the other options are not the best fit:
Azure AI Speech (A) targets spoken audio (speech-to-text, translation, diarization). It’s not intended for detecting the language of text messages. Azure AI
Azure AI Content Safety (B) focuses on safety/moderation (harmful or unsafe content), not language identification.
Azure AI Language (D) also offers a Language Detection feature, but it’s typically used within broader text analytics workflows. For real-time messaging and potential downstream translation, Translator’s Detect endpoint is the targeted and streamlined choice.
