Short answer: If iPhone dictation is not working in Microsoft Copilot, check which mic you tapped. The keyboard mic needs Enable Dictation turned on in Settings > General > Keyboard. Copilot's own mic needs microphone permission, set under that app in the Settings app. End Copilot Voice before dictating.
Copilot gives its best answers to a proper brief: who the message is for, what has already been agreed, the tone you want and how long the result should be. Typing all of that with your thumbs is slow, so speaking it is the obvious move. Which makes it frustrating when the mic key has gone from the keyboard, or you tap it and nothing is typed, or Copilot's own mic button keeps asking for access, or Copilot starts answering out loud on a quiet train, or your usual keyboard is nowhere to be found the moment you open Copilot with a work account.
On an iPhone, nearly all of this traces back to three facts. First, there are several microphones in and around Copilot, each with a different owner, and they fail for different reasons. The mic on your keyboard belongs to Apple or to your keyboard app. The mic in the message box belongs to Copilot. Copilot Voice is a spoken conversation, which is not dictation at all. Second, Copilot is not one app on an iPhone. It can be the Copilot app, the Microsoft 365 Copilot app, a panel inside Word, Outlook or Teams, a button in Edge, or a website in Safari, and iOS gives each of those apps its own microphone permission. Third, if you sign in with a work or school account, your organisation may have a say over which keyboards appear and what you can paste, before dictation even starts.
This guide begins by working out which microphone you tapped, then goes through the fixes in the order that finds the cause fastest. If dictation is failing in every app on your phone, start with our full guide to iPhone dictation not working and come back for the Copilot-specific parts.
First, which microphone did you tap?
The mic key on the keyboard
This is Apple dictation, shown on the standard iPhone keyboard. On iPhones with Face ID it sits below the keyboard at the bottom right, and on older models it is next to the space bar. It works in any app with a text field and does not need Copilot's permission. If the cursor is in Copilot's message box, it types there, and nothing is sent until you send it.
Copilot's own mic button
Copilot's message box has a microphone button of its own. What it does depends on which Copilot you are using and on the version. In some places it turns what you say into text in the box. In others it opens a spoken conversation. Either way it is Microsoft's voice input, not Apple's, and it needs microphone permission for the app it is in and a working connection.
Copilot Voice
Copilot Voice is a conversation. You talk, Copilot answers out loud, and nothing is placed in the message box for you to check first. It is useful when your hands are busy, but it is not a way to write a prompt, and while it runs it holds your iPhone's microphone and audio.
The Dictate button in Word and Outlook
Microsoft's Office apps on iPhone have their own Dictate microphone, usually in the toolbar above the keyboard. It is a Microsoft 365 feature that needs you to be signed in and online, and it is built to write into the document or email you are working on. It is not a way to speak to the Copilot panel, however close the two buttons sit. Fix 6 covers what happens when they get mixed up.
A third-party keyboard's mic
If you use a keyboard such as Voice Keyboard Pro or Gboard, its mic uses that keyboard's own transcription service and settings. Third-party keyboards usually need Full Access turned on to use the microphone and reach the internet.
The fixes barely overlap. Giving Copilot microphone permission does nothing for the keyboard mic, and turning on Enable Dictation does nothing for Copilot's button. Knowing which one failed removes most of the guesswork.
The 30-second Notes test
Before you change any settings, open the Notes app, start a new note, tap the keyboard mic and say one sentence.
- It fails in Notes too. The problem is your iPhone's dictation settings, keyboard or connection, not Copilot. Go to fixes 1 and 10.
- It works in Notes, fails in Copilot. The message box probably does not have the cursor, or a voice conversation is holding the microphone. Go to fixes 2 and 4.
- The keyboard mic works in Copilot, but Copilot's own mic does not. That is a permission problem. Go to fix 3.
- Your usual keyboard does not appear in Copilot, or paste is refused. A work account policy is the likely cause. Go to fix 5.
- Your words went into the document or the email. The cursor was in the file, not in the Copilot panel. Go to fix 6.
- It works, but the prompt goes too early or stops halfway. Dictation is reaching Copilot. Go to fixes 7 and 8.
- It works, but Copilot answers a different question. Your words arrived, but not the ones you said. Go to fix 9.
The 10 fixes, matched to what you see
1. There is no mic key on the keyboard
If the keyboard has no microphone at all, dictation is switched off for the whole phone, not just in Copilot. Open Settings > General > Keyboard and turn on Enable Dictation. If it is already on, turn it off and back on.
If Enable Dictation is on and the mic is still missing, check which keyboard is showing. Tap the globe key to cycle through your keyboards. A third-party keyboard without its own mic, or an emoji or language keyboard, will not show Apple's mic key. On a phone managed by an employer or a school, dictation can also be turned off for the whole device, in which case the switch is missing or cannot be changed. Our guide to the microphone button missing on the iPhone keyboard covers the less common causes.
2. The mic key is there, but nothing is typed
Dictation types at the cursor, so the cursor has to be in a text box. Much of Copilot is not one. A reply is text you can scroll, select and copy, but not type into. The home screen is a set of cards and suggestions. The list of past conversations is a list. On any of those screens the keyboard may be left over from a moment ago with nowhere for the words to go.
Tap the message box at the bottom of the screen and check that a cursor is blinking there, then tap the mic. While a reply is still being written, the box can lose the cursor even though the keyboard looks ready, so if you spoke straight after sending a prompt, tap the box again and repeat it.
Also check for anything open on top of the conversation. An image viewer, a share sheet, a file picker, an account menu or a settings panel sits above the message box and takes your taps. Close it first.
3. Copilot's own mic button does nothing, or keeps asking
This button needs microphone permission for the app it lives in. If you tapped Don't Allow the first time the app asked, it will not ask again, and the button either does nothing or shows a message about access. Open the Settings app, find the app (under Apps on recent versions of iOS) and turn Microphone on. Then force-quit the app and open it again.
The catch is that "the app" may not be the one you expect. iOS keeps a separate microphone switch for each of these:
- The Copilot app. The consumer app has its own switch.
- The Microsoft 365 Copilot app. This is a different app with a different switch, even though the name is nearly the same.
- Word, Excel, PowerPoint, Outlook and Teams. Each has its own, and each one covers the Copilot panel inside that app.
- Edge. The Copilot button in Edge uses Edge's permission.
- Safari. For the Copilot website, the permission belongs to Safari and to the site. Check Safari's Microphone setting in the Settings app and the website settings for the Copilot page.
Allowing one does nothing for the others, so a mic button that works in the Copilot app can still be blocked in Outlook. If a switch is missing or cannot be changed, a Screen Time or device management setting may be preventing apps from using the microphone. Check Settings > Screen Time > Content & Privacy Restrictions, or ask whoever manages the phone. None of this affects the keyboard mic, which is a quick way to keep working while you sort it out.
4. Copilot started talking back
You started a voice conversation when you wanted text, or one was still running from earlier. In Copilot Voice, Copilot is listening for a conversation, not typing into the message box, and it holds the microphone. That can stop the keyboard mic from working until the conversation ends. It can also start without you meaning it to. If you open Copilot from a widget, a shortcut or the Action button, it may be set up to go straight into voice.
End the voice conversation completely, and check the top of the screen or the Dynamic Island for any sign that the microphone is still in use. Then tap back into the message box and use the keyboard mic. If you like talking a problem through, a good pattern is to do that in Copilot Voice, end it, and then dictate one precise written prompt asking for exactly what you decided you need.
5. Your usual keyboard is missing, or you cannot paste
This is the most Copilot-specific problem on the list, and it mostly affects people who sign in with a work or school account. Organisations that let staff use Microsoft apps on their phones can apply protection policies to those apps. Two common settings matter for dictation:
- Third-party keyboards can be blocked. Inside a managed app, iOS shows only Apple's keyboard. Your dictation keyboard works in Notes and Messages and then is simply absent from the globe key list in the Microsoft 365 Copilot app, Outlook, Teams or Word.
- Copy and paste can be restricted. Text copied from a personal app may not paste into a work app. If you dictated a long prompt in Notes and tried to paste it into Copilot, you may see a message along the lines of "Your organization's data cannot be pasted here."
Neither is a fault, and neither can be changed from your phone. The Apple keyboard and its mic key normally keep working inside managed apps, so use that there. If the policy gets in the way of your work, your IT team is the one to ask. And if your prompt is not about confidential work, check which account you are signed in with. Copilot with a personal Microsoft account and Copilot with a work account are different services with different rules, and the app may let you switch between them.
One related surprise: iOS always shows Apple's own keyboard for password fields, whichever keyboard you normally use. If your keyboard changed on a Microsoft sign-in screen, that is expected, and your usual one comes back once you are past it.
6. In Word, Outlook or Teams, your words went into the document
Inside an Office app, Copilot opens as a panel or a prompt box on top of your work, and the work itself is one large text field. The keyboard types wherever the cursor is. If the cursor is still in the document or the email body when you tap the mic key, the prompt you meant for Copilot lands in the middle of your report.
Tap inside Copilot's box and check that the cursor is blinking there before you speak. If the prompt has already landed in the document, shake to undo or use the app's undo button, or select the stray text, cut it, tap into Copilot's box and paste it there.
The Dictate button in the app's toolbar causes the same result by a different route. It is designed to write into the document or the email, so it is the wrong microphone for a prompt. To speak to Copilot, tap into its box and use the keyboard mic.
The reverse also happens. Depending on the version and your licence, the app can offer a Copilot draft box on a blank document or a new email. If the cursor is in that box, your dictated sentence is treated as an instruction to Copilot and not as text for the page. Our guides to iPhone dictation not working in Microsoft Word and in Outlook cover the document and email side in full.
7. Half a prompt was sent
A prompt sent too early is answered exactly as it stands, so you get a confident reply to a fragment. There are three usual causes:
- Copilot's own mic sent it. Depending on the version, Copilot's voice input may respond when you stop talking instead of leaving the text in the box to review. A pause to think counts as stopping.
- A line break sent it. Depending on the app and version, the return key may send the message instead of starting a new line. If you say "new line" while dictating, or tap return to tidy up, the prompt may go.
- You tapped send out of habit. The send arrow sits close to the keyboard, and it is easy to hit it while reaching for the mic key.
The keyboard mic is the safer choice when you want to review before sending, because it only fills the box. Keep the prompt to one paragraph, read it, then tap send yourself. If a fragment has already gone, stop the reply if you can, then edit the original message where that is offered, or send the complete version as one new message so the whole request sits in one place.
8. Dictation stops partway through a long prompt
Good prompts are long, and long prompts involve pauses. Apple's system dictation can end a session when you stop speaking for a moment. You pause to recall a client's name, and the microphone quietly switches off. What you already said stays in the box, but anything after the pause is lost, and if you do not notice, you send a brief with its most important condition missing.
A few habits make long prompts much more reliable:
- Dictate in sections. Say the task, stop and check it, then tap the mic again for the background, then again for the tone and length you want.
- Think first, then speak. Decide what the next part needs to say before you tap the mic, so you are not pausing mid-sentence.
- Scroll the box. On a phone the message box shows only a few lines. Scroll up inside it to check that the beginning of the prompt is still what you said.
- Draft somewhere safe. For a very long brief, dictate it in Notes first and paste it into Copilot. If the app reloads while you are away from it, your draft survives. On a work account, check that pasting is allowed before you rely on this (see fix 5).
Our guide to iPhone dictation cutting off when you pause explains why this happens and covers more workarounds. For shaping the prompt itself, see our guide on how to dictate in Microsoft Copilot.
9. Copilot answered a different question
Sometimes dictation works perfectly well and the result still looks broken. You ask for a summary of the Henley proposal and get a polite request to share the "handy proposal". Before you blame Copilot, scroll up and read the prompt as it was actually sent. Dictation has to guess at words it has not met, and names of people, clients, projects and products are the words it is least likely to have met. One wrong name changes what the whole prompt is about, and Copilot answers the prompt it was given.
Read the box before you send, and look hardest at names, numbers and abbreviations. If a name came out wrong, fix that word by typing it. If the prompt has already gone, correct it and send it again in full. A follow-up saying "I meant the other one" leaves the wrong name sitting in the conversation.
Two more things bend an answer without any word being misheard. The first is where you asked. A new topic dictated into an existing conversation is read in the light of everything above it, so start a new chat for a new subject. Inside Word, Outlook, Teams or Edge, Copilot can also use the document, email, meeting or page you have open as context, so a loose spoken prompt such as "summarise this" is applied to whatever that is. Name the thing you mean. The second is language. Dictation writes in the language of the active keyboard. If that is not the language you spoke, the text comes out as near nonsense and Copilot does its best with it. Switch keyboards with the globe key and try again.
10. Nothing works, anywhere
If the Notes test failed too, the problem is at the system level, and Copilot is simply where you noticed it.
- Check the connection. Copilot needs a connection to answer, and depending on your language and settings, dictation may too. Third-party keyboard mics always need one. If things fail away from Wi-Fi, check that the app is allowed to use mobile data in Settings > Cellular.
- Turn off Low Power Mode to test. It limits background activity. Our guide to iPhone dictation in Low Power Mode covers what it changes.
- End any call. Dictation is not available while a phone call or a video call is using the microphone, and a Teams meeting counts.
- Check where audio is going. A Bluetooth headset or a car system can take over the microphone. Disconnect it to test. Our guide to iPhone dictation not working with AirPods covers this.
- Check restrictions. Make sure Siri and dictation are not blocked in Settings > Screen Time > Content & Privacy Restrictions. If Enable Dictation itself is greyed out, see our guide to dictation greyed out on iPhone.
- Restart and update. Restart your iPhone, then check for iOS updates and for updates to the Copilot app or your Office apps.
Copilot quirks that look like broken dictation
- The prompt was sent before you finished. That was Copilot's own mic, or a line break. The keyboard mic only fills the box.
- Copilot answered out loud. You were in a voice conversation. End it and use the keyboard mic for a silent, written prompt.
- The reply ignores half of what you said. Look at your message in the conversation. If the second half is missing, dictation stopped at a pause.
- Your dictated text vanished. If you tapped a suggested prompt, started a new chat or left the app long enough for it to reload, the contents of the box were replaced. Long prompts are safer drafted in Notes.
- Your keyboard changed. A password field always shows Apple's keyboard, and a managed work app may allow only Apple's keyboard throughout.
- Paste was refused. A work policy is restricting what can be pasted into the app. See fix 5.
- Your prompt is sitting in the document. The cursor was in the file and not in Copilot's box. See fix 6.
- The mic works in one Microsoft app and not another. Each app has its own microphone switch. See fix 3.
Quick triage
- No mic key on the keyboard: Enable Dictation is off, or the keyboard showing has no mic. Fix 1.
- Mic key does nothing in Copilot: no text box has the cursor. Fix 2.
- Copilot's mic button does nothing or asks for access: microphone permission is off for that app. Fix 3.
- Copilot talks back: a voice conversation was started or is still running. Fix 4.
- Your keyboard is missing or paste is blocked: a work account policy. Fix 5.
- The prompt landed in your document or email: the cursor was in the file, or you used the Dictate button. Fix 6.
- A fragment was sent: Copilot's mic or a line break sent it. Fix 7.
- A long prompt stops midway: dictation ended during a pause. Fix 8.
- The reply is about the wrong thing: a misheard word, an old conversation or the wrong language. Fix 9.
- Fails in Notes as well: connection, a call, audio route or system settings. Fix 10.
Why Copilot prompts are worth speaking on a phone
Most people speak at around 130 to 150 words per minute. The average adult types at about 40 words per minute on a full keyboard, and thumb typing on a phone is usually slower still. For a one-line request the difference hardly matters. For a brief with background, an audience, a tone and a length, which is the kind Copilot handles best, speaking it takes a fraction of the time.
There is a second benefit. Typing on a phone is effort, so typed prompts shrink to a few keywords. Speaking is cheap, so a spoken prompt tends to arrive as full sentences with the reason attached, and that added context gives an assistant more to work with.
Dictation works the same way in other AI apps, and so do its problems. If you use more than one, see our guides to iPhone dictation not working in Gemini, in the Claude app and in Perplexity. If you also use Copilot at a desk, the Mac has its own version of this list: Mac dictation not working in Microsoft Copilot.
A keyboard built around dictation
Most of the problems above come from juggling microphones with different owners, and from system dictation's habit of stopping when you pause. A dictation keyboard puts one consistent mic in every app where keyboards are allowed.
Voice Keyboard Pro is a custom iPhone keyboard with a built-in mic button for dictation in any iOS app, Copilot included. Tap into the message box, tap the mic, speak, and the text appears in the box, ready to review and send. It never sends anything for you, and because it is a keyboard and not a feature of one app, it behaves the same way in Copilot, Notes, Messages and everywhere else you type.
A few features fit Copilot prompts particularly well:
- Voice Edit lets you speak a change to fix text. If a dictated prompt has a detail wrong, say the correction instead of fiddling with the cursor on a small screen.
- Two-way translation while dictating covers 24 languages, which helps if you think in one language and need the prompt, or the email it produces, in another.
- Swipe typing is built in, so you can fix a single name or type something you would rather not say out loud without switching keyboards.
One honest limit: if your organisation blocks third-party keyboards in its managed apps, Voice Keyboard Pro will not appear in those apps, and no keyboard can get round that. It still works everywhere else on the phone, including the Copilot app with a personal account.
Setting it up takes a minute: add the keyboard in Settings, then allow Full Access so it can reach the transcription service. Our guide to what Full Access does for an iPhone keyboard explains what it grants. On privacy, our servers store only operational pings. No audio and no transcript content is stored, which matters when your prompts describe what you are working on. There is a free tier with daily limits, and Pro is $4.99 a month or $34.99 a year.
If you also write prompts at a desk, Voice Keyboard Pro for Mac is a menu bar app: hold a hotkey, speak, release, and the text appears at your cursor, in Copilot and in every other app.
Frequently asked questions
Why does the keyboard mic work in Copilot when Copilot's own mic button does not?
They are different systems. The keyboard mic is Apple dictation, or your keyboard app's dictation, and does not need Copilot's permission. Copilot's button is Microsoft's voice input and needs microphone permission for the app it is in. Turn on Microphone for that app in the Settings app.
Is Copilot Voice the same as dictation?
No. Copilot Voice is a spoken conversation in which Copilot answers out loud. Dictation turns your speech into text in the message box for you to review and send. For a written prompt, end the voice conversation and use the keyboard mic.
Why is my third-party keyboard missing in Copilot on my work account?
Organisations can block third-party keyboards inside the apps they manage. When that policy is on, only Apple's keyboard appears in those apps. It cannot be changed from the phone. Use the Apple keyboard's mic key there, or ask your IT team.
Why can I not paste my dictated prompt into Copilot?
A work policy can restrict pasting from personal apps into managed apps. Dictate directly into Copilot's message box with the keyboard mic instead of drafting elsewhere.
Why did my prompt end up in my Word document or my email?
The keyboard types where the cursor is, and in Word or Outlook the cursor is usually in the document or the message. Tap inside Copilot's box first. The Dictate button in those apps also writes into the document, not into Copilot.
Does dictation work with Copilot in Safari?
Yes. The keyboard mic works in the message box on the Copilot website just as it does in the app. Tap into the box first so the keyboard appears. Any voice buttons on the website are separate and depend on Safari's microphone permission for the site.
Why does the mic button work in the Copilot app but not in Outlook or Teams?
iOS gives every app its own microphone switch. Allowing the Copilot app does nothing for Outlook, Teams, Word or Edge. Open the Settings app, find the app where it fails and turn Microphone on.
What to do next
Run the Notes test, then tap into Copilot's message box until the cursor blinks and use the keyboard mic. Those two steps settle most Copilot dictation problems on an iPhone. If only Copilot's own mic fails, turn on the microphone for that particular app. If Copilot talks back, end the voice conversation. If your keyboard is missing on a work account, that is policy, so use Apple's keyboard there. If the prompt lands in a document, tap into Copilot's box before you speak. And if a fragment gets sent, keep the prompt to one paragraph and tap send yourself.
If you want one dictation mic that behaves the same in Copilot and every other app on your phone, Voice Keyboard Pro has a free tier. Add the keyboard, open Copilot and say your next prompt.
The words land at your cursor in whatever app you are already in: Copilot, Outlook, Word, a browser form. No dictation window, nothing to copy across.
