You plan to build a conversational AI solution that can be surfaced in Microsoft Teams, Microsoft Cortana, and Amazon Alexa. Which service should you use?

Azure Bot Service provides a comprehensive platform for developing, connecting, and managing intelligent bots, offering direct integration with numerous popular channels including Microsoft Teams, Cortana, and Amazon Alexa. It abstracts away the channel-specific integration complexities.

Azure Cognitive Search is used for adding search capabilities to applications, not for building conversational AI agents.

Azure AI Speech service is primarily for converting speech to text and text to speech, which is a component of a conversational AI but not the complete solution for channel integration.

Azure AI Language service provides natural language processing capabilities like sentiment analysis or language understanding, which are components of a bot but not the service for managing channel connections.
