Short answer: If iPhone dictation is not working in Gemini, first check which mic you tapped. The keyboard mic needs Enable Dictation turned on in Settings > General > Keyboard. Gemini's own mic needs microphone permission, set under Gemini in the Settings app. End any Gemini Live session before dictating.
Google's Gemini app is at its best with detailed prompts: the background, what you want, the format, what to avoid. Typing all of that with your thumbs is slow, so dictating it is the natural move. Which makes it frustrating when the mic key has disappeared from the keyboard, or you tap it and nothing is typed, or Gemini's own mic button keeps asking for permission, or Gemini starts talking back when you only wanted to type, or your carefully spoken prompt stops halfway through a sentence.
Almost every one of these comes down to one thing. There are several different microphones in and around the Gemini app, 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 Gemini's prompt box belongs to Google. The Live button starts a spoken conversation, which is not dictation at all. Fixing the wrong one wastes time, so this guide starts by working out which mic you are using, then goes through the fixes in the order that solves the problem 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 Gemini-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 Gemini's permission. If the cursor is in Gemini's prompt box, it types there, and nothing is sent until you tap send.
Gemini's own mic button
The Gemini app has a microphone in its prompt bar. It is Google's voice input, not Apple's, and it has its own requirements: microphone permission for the Gemini app, a signed-in Google account and a working connection. Depending on the version of the app, it may send your prompt as soon as you stop talking rather than leaving it in the box to review.
Gemini Live
Gemini Live is a spoken conversation. You talk, Gemini answers out loud, and you can interrupt it. It is great for thinking out loud, but it is not a way to write a prompt, and while it is running it holds your iPhone's microphone and audio.
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 Gemini microphone permission does nothing for the keyboard mic, and turning on Enable Dictation does nothing for Gemini's button.
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 Gemini. Go to fixes 1, 8 and 9.
- It works in Notes, fails in Gemini. The prompt box probably does not have focus, or Live is holding the microphone. Go to fixes 2 and 4.
- The keyboard mic works in Gemini, but Gemini's own mic does not. The problem is Gemini's permission or account. Go to fixes 3 and 7.
- It works, but stops early or your words go missing. Dictation is reaching Gemini. Go to fixes 5 and 6.
The 9 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 Gemini. 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. Our guide to the microphone button missing on the iPhone keyboard covers the less common causes, including restrictions that hide it.
2. The mic key is there, but nothing is typed
Dictation types at the cursor, so the cursor has to be in Gemini's prompt box. After you send a prompt, or while a response is still appearing, the box can lose focus even though the keyboard looks ready. Tap directly in the prompt box, check that a cursor is blinking there, then tap the mic.
Also check where you are in the app. If the chat list, a settings screen or an image preview is open, there may be no prompt box on screen at all. Go back to a chat, tap the box and try again. If you are editing a prompt you already sent, make sure the edit field is open and has the cursor, not the main box below it.
3. Gemini's own mic button does nothing, or keeps asking
This button needs microphone permission for the Gemini app. If you tapped Don't Allow the first time Gemini asked, it will not ask again, and the button either does nothing or shows a message about access. Open the Settings app, find Gemini (under Apps on recent versions of iOS), and turn Microphone on. If Gemini lists Speech Recognition as well, turn that on too. Then force-quit Gemini and open it again.
If the 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. Remember that none of this affects the keyboard mic, which is a quick way to keep working while you sort it out.
4. Gemini started talking back
You tapped the Live button instead of the mic, or a Live session was still running. While Live is active, Gemini is listening for conversation, not typing into the prompt box, and it holds the microphone. That can stop the keyboard mic from working until Live ends. End the Live session completely, and check the top of the screen or the Dynamic Island for any sign it is still running. Then tap back into the prompt box and use the keyboard mic.
If you like Live for brainstorming, a good pattern is to talk an idea through in Live, end it, then dictate a clean prompt with the keyboard mic that asks for exactly what you decided.
5. Dictation stops partway through a long prompt
This is the most Gemini-specific problem on the list, because good Gemini prompts are long, and long prompts involve pauses. Apple's system dictation can end a session when you stop speaking for a moment, and there are limits on how long a single session runs. You pause to decide how to phrase the next requirement, and the microphone quietly switches off. What you already said stays in the box, but anything after the pause is lost.
A few habits make long prompts much more reliable:
- Dictate in sections. Speak the background, stop and check it, then tap the mic again for the instructions, then again for the format you want back.
- Think first, then speak. Decide what the next section needs to say before you tap the mic, so you are not pausing mid-sentence.
- Draft somewhere safe. For a very long prompt, dictate it in Notes first and paste it into Gemini. If anything goes wrong in the app, your draft survives.
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 Gemini prompts by voice.
6. Words appear, then vanish, or land in the wrong place
If your words show up and then disappear, something replaced or cleared the prompt box. Common causes:
- Switching chats or apps mid-draft. Starting a new chat, opening a different conversation or leaving the app for a while can clear an unsent draft. Finish and send, or copy your text before you switch.
- Apple dictation revising itself. Apple dictation sometimes changes earlier words as it hears more context. Usually that improves the text, but now and then it replaces a phrase you meant. Read the prompt before you send it.
- The cursor was not at the end. If you tapped into the middle of existing text, dictation inserts there, so new words can appear in the middle of your prompt. Tap at the end of the text before you speak.
- Gemini's own mic sent it early. If you used Gemini's mic and it submitted before you finished, your half-prompt is now a message in the chat rather than a draft. Use the keyboard mic when you want to review before sending.
7. Gemini asks you to sign in, or is not available
Gemini needs you to be signed in with a Google account, and what you can use depends on that account. If you are signed in with a work or school account, your administrator may have turned Gemini off or limited it. Google also restricts Gemini for some age groups and regions. If Gemini shows a sign-in screen or an unavailable message, there is no prompt box to dictate into, so no dictation fix will help. Switch to a personal account from your profile picture in the app, or ask your administrator. You can check which account is active by tapping your profile picture.
8. It works on Wi-Fi but not on cellular, or it is very slow
Gemini needs a connection to answer, and depending on your language and settings, dictation may too. Third-party keyboard mics always need one. If dictation fails or crawls away from Wi-Fi, check that Gemini is allowed to use mobile data in Settings > Cellular, and try a different network. If Low Power Mode is on, turn it off to test, since it limits background activity. Our guide to iPhone dictation in Low Power Mode covers what it changes.
9. Nothing works, anywhere
If the Notes test failed too, work through the system-level fixes. Restart your iPhone. Check for iOS updates. Make sure Siri and dictation are not blocked in Settings > Screen Time > Content & Privacy Restrictions. Check the dictation language: if you speak a language that is not added as a keyboard, dictation may not recognize it. As a last resort, Settings > General > Transfer or Reset iPhone > Reset > Reset Keyboard Dictionary clears learned words without touching your data. If Enable Dictation itself is greyed out, see our guide to dictation greyed out on iPhone.
Gemini quirks that look like broken dictation
- Your prompt was sent before you finished. That was Gemini's own mic, not the keyboard. The keyboard mic only fills the box.
- Gemini answered out loud. You were in Live, or you asked by voice in a mode that replies with speech. Use the keyboard mic for silent, typed prompts.
- Punctuation is missing or odd. Apple dictation adds punctuation automatically in many languages, but it guesses. You can also say punctuation, such as "comma", "question mark" or "new line", and fix the rest by hand before you send.
- Product names and technical terms come out wrong. Dictation guesses at unusual words. Spell them out once by typing, or check them before you send, since Gemini can only answer what it was actually asked.

Why prompts are worth speaking
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 quick question the difference hardly matters. For the kind of prompt that gets a genuinely useful answer from Gemini, with context, constraints and an example of what you want, speaking it can take a fraction of the time. People also tend to include more detail when they talk than when they type, simply because it costs less effort, and more detail usually means a better answer.
Dictation works in other AI apps the same way, and so do its problems. If you use ChatGPT too, our guide to iPhone dictation not working in ChatGPT covers its version of the same issues.
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.
Voice Keyboard Pro is a custom iPhone keyboard with a built-in mic button for dictation in any iOS app, Gemini included. Tap into the prompt 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 rather than a feature of one app, it behaves the same way in Gemini, Notes, Messages and everywhere else you type.
A few features fit prompt writing 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 want the prompt in another.
- Swipe typing is built in, so you can fix a single word or type something you would rather not say out loud without switching keyboards.
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. There is a free tier with daily limits, and Pro is $4.99 a month or $34.99 a year.
Frequently asked questions
Why does the keyboard mic work in Gemini when Gemini'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 Gemini's permission. Gemini's button is Google's voice input and needs microphone permission for the Gemini app. If only Gemini's button fails, turn on Microphone for Gemini in the Settings app.
Is Gemini Live the same as dictation?
No. Live is a spoken conversation in which Gemini answers out loud. Dictation turns your speech into text in the prompt box for you to review and send. If you want a written prompt, use the keyboard mic and make sure Live has ended.
Why does dictation stop when I pause in the middle of a prompt?
Apple's system dictation can end a session after a short silence, or after a session has run for a while. Dictate in sections, decide what to say before you tap the mic, and draft very long prompts in Notes first.
Why does dictation work in other apps but not in Gemini?
If the keyboard mic works in Notes but not in Gemini, the prompt box probably does not have the cursor, or a Live session is holding the microphone. Tap into the box, end Live, and try again.
Does dictation work with Gemini in Safari?
Yes. The keyboard mic works in the prompt box on the Gemini 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.
What to do next
Run the Notes test, then tap into Gemini's prompt box until the cursor blinks and use the keyboard mic. Those two steps resolve most Gemini dictation problems on iPhone. If only Gemini's own mic fails, give Gemini microphone permission. If Gemini talks back, end Live. If a long prompt cuts off, dictate it in sections.
And if you want one dictation mic that behaves the same in Gemini and every other app on your phone, Voice Keyboard Pro has a free tier. Add the keyboard, open Gemini and say your next prompt.
The words land at your cursor in whatever app you are already in — Mail, Slack, Word, a browser form. No dictation window, nothing to copy across.
