Activate text to voice by selecting the “dictate” microphone button.
Once selected, you will see "Listening..." in the prompt box. When you are done talking, click on the blue Microphone icon to stop dictation. At that point, Copilot stops listening.
Prompting Best Practices
- Just talk out your ideas and needs openly and abundantly. Think out loud. After all, you are talking to your digital employee! This works because Large Language Models excel at synthesizing unstructured data (i.e. word vomit). No need to edit yourself mid-sentence.
- Call out uncertainties as you go. Phrases like: "I’m not sure about this part…" help the model know where to focus synthesis and options.
Technical Details
Automatic punctuation and formatting
The model inserts punctuation, capitalization, and paragraph breaks automatically. You can also dictate formatting explicitly (“new paragraph,” “comma,” “period”) if higher precision is needed.
Long-form memory window
Voice mode supports extended monologues. You can speak for several minutes at a time, and the transcription will remain cohesive enough for the model to synthesize into structured output afterward.
