One of the quickest and most efficient ways to interact with Bing Chat is just by using your voice like talking to Cortana. However, it appears the ability to use the microphone is only available if you go to the Bing Chat webpage. If you click the Bing icon in the top right of the Edge browser (running on Windows 11) to open up Bing Chat you do not have the option to use the microphone. I have yet to find a solution to be able to use the microphone with Bing Chat launched from the Edge sidebar.
