Which Azure Cognitive Services can help in recognizing different languages during a call?

Text Analytics
Speech Service
Computer Vision
Face API

The correct answer is: Speech Service

The Speech Service is designed to recognize and convert spoken language into text, and it includes capabilities for language identification. This service is particularly relevant in scenarios involving voice communication, such as phone calls, where it automatically detects the language being spoken by the user. The ability to identify and switch between multiple languages in real-time makes it an essential tool for applications needing to process spoken language accurately. The other options presented do not fulfill this specific function. For example, Text Analytics focuses on extracting insights from text data, such as sentiment analysis and key phrase extraction, rather than processing spoken language. Computer Vision is centered on interpreting visual information from images and videos, and the Face API is specialized in facial recognition and analysis. Consequently, these services do not provide features for language recognition during calls, making the Speech Service the appropriate choice.
