AI chat · Dictation workflow

Copilot dictation on Mac and Windows Talk through the whole request, then read it before Copilot does.

Copilot gives you two ways to talk to it, and they do different jobs. Start dictation types your speech into the prompt box so you can edit it before sending, and Microsoft lists it for work or school accounts. Copilot Voice is a spoken conversation that answers out loud, and personal accounts get it too. No Start dictation button? Windows key + H and Mac Dictation can type into the same box. With VoiceSnap Pro, you hold one key, say the whole request and let go; the punctuated prompt appears in the box for you to check and send.

How to use dictation and voice in Microsoft Copilot

What Copilot offers depends on how you sign in. Microsoft’s voice guide lists Dictation, for speaking a prompt instead of typing it, for work or school accounts only. Copilot Voice, a real-time spoken conversation, is listed for work, school and personal accounts. Both depend on your subscription and region, and Microsoft is releasing them gradually. If you want a written prompt and see no Start dictation button, use the dictation built into Windows or macOS in the prompt box.

Copilot: Start dictation (work or school account)

  1. Sign in with your work or school account at copilot.cloud.microsoft, or in the Microsoft Copilot app on your desktop.
  2. Click in the Message Copilot box and select the microphone icon, Start dictation, in its lower-right corner.
  3. If your browser or device asks, allow microphone access. You can change that choice later in its settings.
  4. Speak. Copilot writes your words into the box as you talk. Say “period”, “comma” or “new line” where you want them.
  5. Select Stop dictation when you finish, and Copilot stops listening.
  6. Read the prompt before you send it. Microsoft warns that speech can be misheard and advises cutting background noise.

Copilot Voice: talk and hear the answer

  1. Open Copilot on the web or in the Copilot app. On Windows, the Copilot key or Windows key + C opens the app or its smaller Quick View, as set under Account → Settings → Copilot Keyboard Shortcuts, and both have the voice icon.
  2. Select the Voice icon in the message composer. In a work or school account it sits next to Start dictation and is called Start a new voice chat.
  3. Allow the microphone if asked, wait for Copilot’s audio greeting, then speak. Copilot answers out loud, and you can interrupt it.
  4. Select the Microphone icon to mute or resume yourself, and the X icon to end the chat; in Quick View, use Mute and Dismiss. A text transcript is there when it ends.
  5. In the Copilot app on Windows, you can also start a chat by saying “Hey Copilot”. It is off by default: select Settings at the bottom of the left menu and turn on Listen for “Hey Copilot”, which sits under General, or under Quick View in some versions.

No Start dictation button: Windows key + H or Mac Dictation

  1. Windows 11: click in the Copilot prompt box and press Windows key + H. Speak once “Listening...” shows; you need to be online.
  2. Windows 11: say “comma” or “question mark”, or turn on Automatic punctuation under the gear icon. Say “stop listening” to finish. On Windows 10, the same keys open the dictation toolbar, and “stop dictation” ends it.
  3. Mac: switch on Dictation once in System Settings → Keyboard → Dictation, and note the shortcut it shows.
  4. Mac: click in the Copilot prompt box, or press Option + Space to open the Copilot app’s small prompt window. Start Dictation with the Microphone key, your shortcut or Edit → Start Dictation; in supported languages it adds the punctuation.
  5. Mac: press Escape, the Microphone key or the shortcut to stop. Dictation also ends after 30 seconds with no speech.

Where the built-in option stops

  • Microsoft lists Start dictation and Read aloud for work or school accounts only, and in a work context voice is not yet available without a Microsoft Copilot license. On a personal account, the guide offers Copilot Voice, which answers out loud instead of typing your prompt.
  • Microsoft’s dictation steps have you say “period”, “comma” and “new line”. They do not mention punctuation added for you.
  • A voice chat can’t create images or files or @-mention agents today, Microsoft says, and its answers may be shorter. Microsoft notes that voice and text use different models.
  • Voice chats are time limited and can disconnect on their own. On Windows, a Quick View or “Hey Copilot” chat warns you after 30 seconds without speech and ends after a minute, though background noise can keep it listening. Audio from another app interrupts any voice chat, and background speech can be picked up.
  • “Hey Copilot” works only in the Copilot app on Windows and only while the app is running, and the wake word itself must be said in English. It can’t start a chat when the screen is locked or another app is playing audio.

From cursor to draft

How to dictate in Microsoft Copilot with VoiceSnap Pro

First install VoiceSnap Pro, sign in and complete the microphone and system-permission prompts. Then keep the app running while you write.

Read the getting-started guide
  1. Click in the prompt box, with Copilot’s mic off

    Open Copilot in your browser or the desktop app and click in the Message Copilot box. End any voice chat with the X icon and leave Start dictation off, or Copilot will hear the words you are about to dictate. Nothing needs installing in Copilot or the browser.

  2. Say the background, the task and the answer you want

    Hold Right Option on a Mac or Right Alt on Windows, or the key you picked in Settings → Shortcuts. Say what Copilot needs to know, what you want from it and the form of the answer, without saying the punctuation. Let go, and the whole prompt arrives in the box in one piece. Clean up dictation, on by default, takes out fillers and the words you take back as you speak, and leaves the rest of your words as you said them. Stay in Copilot until the text appears.

  3. Paste what must be exact, then send

    Paste the email, table or passage your request refers to, and type names, figures and links that must be exact. Add any line breaks with the keyboard, taking care not to send a half-finished prompt. Read the prompt the way Copilot will, then send it yourself: VoiceSnap Pro types the text and never presses Enter.

Three useful ways to write in Microsoft Copilot

A research question with constraints

Say the question, then the limits that make the answer useful to you: the region, the time frame, what you already know and what to leave out. Ask for sources you can open, and check them before you rely on the answer.

A question about a work file

Add the file first: in Copilot Chat, select the plus icon in the Message Copilot box, then Add and manage sources, and upload it or attach it from OneDrive. Then dictate what you need from it, who the answer is for and what to leave out, so Copilot works from the document rather than your summary of it.

A task for an agent

Open the agent from Agents in Copilot’s navigation panel, then hold the key and say the task, the inputs and the result you want. Microsoft says voice chats aren’t supported in Copilot agents yet, so a written prompt, typed or dictated, is how you brief one.

The human part

Make the draft yours.

Read the day and the count: the prompt should ask for six questions, not five. Add the supplier’s name and the order details you want Copilot to use, then send it.

  • Put the form of the answer last, such as a table, five bullet points or one paragraph, so you can tell at a glance whether you got it.
  • Need an image, a file or an agent? Write the prompt as text, by dictation or keyboard. Microsoft says a voice chat can’t do those yet.
  • Company acronyms and project names are where a spoken prompt is likeliest to slip. Add the ones you use with Copilot to personal vocabulary, and still read them before you send.
  • Saying a file’s name does not attach it. Add the file with Copilot’s own controls before you send.

When dictation in Microsoft Copilot doesn’t work

There is no Start dictation button in Copilot
Microsoft lists dictation for work or school accounts only, and releases voice gradually by subscription and region. Sign in with your work or school account at copilot.cloud.microsoft or in the Copilot app. In a work context, Microsoft says voice is not yet available without a Microsoft Copilot license. On a personal account, click in the prompt box and type the prompt with Windows key + H or Mac Dictation, or hold your VoiceSnap Pro key.
Copilot can’t use your microphone
Copilot may ask for microphone access the first time you use voice. If you said no on the web, select the lock or site-information icon in the address bar in Edge or Chrome, set Microphone to Allow and try again. On Windows 11, open Start → Settings → Privacy & security → Microphone and turn on Microphone access, Let apps access your microphone and, for the desktop app, Let desktop apps access your microphone. On a Mac, open System Settings → Privacy & Security → Microphone and turn on your browser or the Copilot app.
A Copilot voice chat ends by itself, or won’t stop listening
Voice chats have session limits and can disconnect when one is reached; Microsoft says signing in to the Copilot app gives you extended voice sessions. On Windows, a Quick View or “Hey Copilot” chat warns you after 30 seconds without speech and ends after a minute, while background noise can keep it listening. Audio from another app interrupts a voice chat. Move somewhere quiet, pause other audio and end the chat with the X icon, or Dismiss in Quick View. To carry on by text, select the chat under Chats and type in the Message Copilot box.
“Hey Copilot” doesn’t start a chat
The wake word works only in the Copilot app on Windows, and only after you turn on Listen for “Hey Copilot” in its Settings, under General or, in some versions, Quick View. Keep the app running and the screen unlocked, stop other audio and check that you are online. Say it in English; the chat can then continue in another supported language. On a Mac or the web, select the Voice icon instead.
Windows key + H or Mac Dictation won’t type in Copilot
Click inside the prompt box first so the cursor is there. On Windows, check your connection and choose the right Default microphone from the voice typing gear icon. On a Mac, check Dictation is on in System Settings → Keyboard, pick the Microphone source you use there, and turn Voice Control off.
VoiceSnap Pro’s prompt didn’t appear in Copilot
Keep Copilot in front, with the cursor in the prompt box, until the text arrives. While you hold the key, the mic pill shows “Listening…” with the app it will type into; with Copilot in a browser tab, that is your browser, such as “Microsoft Edge”. If it names any other app, press Escape, click in the Copilot prompt box and start again. Check your internet connection. On a Mac, VoiceSnap Pro needs Microphone, Accessibility and Input Monitoring under System Settings → Privacy & Security; quit and reopen it after turning on the last two. To get the words back without saying them again, click the prompt box and use Paste last dictation: Control + Option + V, or Ctrl + Alt + V on Windows.

Choose what fits

Dictation, a voice chat or one held key

With a work or school account and the occasional prompt, Start dictation is enough: you see the words as you speak and send them when they read right. To think out loud and hear answers, start a Copilot Voice chat, on a personal or a work or school account where your plan and region include it, and switch back to text when you need images, files or agents. On a personal account, Windows key + H or Mac Dictation types a prompt into the box; Mac Dictation punctuates as you go in supported languages, and Windows does once Automatic punctuation is on.

Where VoiceSnap Pro fits

VoiceSnap Pro fits when you write long prompts often, in Copilot and in the apps you copy from, on a Mac, a Windows PC or both. You hold the same key in every app and let go when the prompt is complete; silence alone doesn’t stop the recording. Clean up dictation drops fillers and corrected slips from dictations of up to about five minutes, without rewording, and personal vocabulary gives transcription your names and terms as spelling hints. It needs an internet connection, shows the text only after you let go, takes no spoken commands and never answers out loud. There is a free allowance to start, and no card is needed.
