Which AI service should you use to create a bot from a frequently asked questions (FAQ) document?

The Azure AI Language service (formerly Azure Cognitive Service for Language) offers various natural language processing capabilities, including question answering (QnA Maker), which is specifically designed to build conversational AI experiences from FAQ documents and other knowledge bases.

Language Understanding (LUIS), now a feature within the Azure AI Language service, focuses on understanding user intents and entities in natural language, not on directly creating a bot from an FAQ document.

Text Analytics, also part of the Azure AI Language service, provides features like sentiment analysis, key phrase extraction, and entity recognition, but it does not create a conversational bot from an FAQ document.

Speech services enable voice input and output for a bot, but they do not process an FAQ document to build the bot's conversational knowledge.
