Dictation lets you use speech-to-text to author content in Microsoft 365 with a microphone and reliable internet connection. It's a quick and easy way to get your thoughts out, create drafts or outlines, and capture notes. Open a new or existing document and go to Home > Dictate while signed into Microsoft 365 on a mic-enabled device. More @Wikipedia
