You are building a bot by using Microsoft Bot Framework. You need to configure the bot to respond to spoken requests. The solution must minimize development effort. What should you do?

While Direct Line Speech offers robust voice capabilities, it typically requires more development effort to integrate the client-side SDK into custom applications, which doesn't align with minimizing development effort.

Integrating a bot with Cortana via the Bot Framework SDK provides a ready-made channel for handling spoken requests, leveraging Cortana's built-in speech capabilities. This approach minimizes development effort compared to building custom speech integration, as the Bot Framework channel abstracts much of the underlying speech processing complexities.

Creating an Azure function to call the Speech service and connect it to the bot introduces additional custom development and management overhead, increasing effort.

Microsoft Teams supports text and some voice/video calls, but it's not primarily a channel for generic voice-driven bot interactions in a way that inherently minimizes effort for spoken requests compared to a dedicated voice assistant channel.
