Short answer: If iPhone dictation stopped working after the iOS 18 update, re-enable it under Settings → General → Keyboard → Enable Dictation, confirm microphone access is on, and check that Screen Time isn't blocking it. Most cases are a permission or toggle reset by the update, not a hardware fault.
You updated to iOS 18, and now the little microphone button on your keyboard does nothing. Maybe it greys out. Maybe it disappeared entirely. Maybe it listens for a second and then quits before you finish your sentence. Whatever the symptom, you are not imagining it: major iOS updates have a long history of quietly flipping settings, resetting permissions, and reshuffling menus, and dictation is one of the features most often caught in the crossfire.
The good news is that almost every case where iPhone dictation stopped working after the iOS 18 update comes down to a setting that needs to be switched back on, a permission the update revoked, or a small piece of state that got corrupted and needs a refresh. Genuine hardware failure is rare. Below are eleven fixes, ordered from the most common cause to the least, so you can work straight down the list and stop at the one that solves it.
First, Confirm What "Not Working" Actually Means
Before you start toggling settings, take ten seconds to pin down the exact symptom. The fix is different depending on what you see:
- The mic button is missing from the keyboard. Dictation has been disabled in Settings, or a third-party keyboard without dictation is active.
- The mic button is greyed out or won't tap. A restriction (Screen Time) or a permission is blocking it.
- You tap it, it listens, then nothing appears. Microphone access, a network problem, or a stuck background process.
- It types a few words then cuts off. The built-in engine timed out on a pause, which is a known design limit rather than a bug.
- It types the wrong words or the wrong language. A language or dictation-language mismatch.
Hold your specific symptom in mind as you go. Now let's fix it.
1. Re-Enable Dictation in Settings
This is the single most common reason dictation vanishes after an update, and it is the first thing to check. iOS 18 occasionally resets the master dictation switch to off, which makes the mic button disappear from every keyboard at once.
- Open Settings.
- Tap General, then Keyboard.
- Scroll down to Enable Dictation.
- If the toggle is off, switch it on and confirm when prompted.
If it was already on, switch it off, wait five seconds, and switch it back on. This forces the system to reinitialize the dictation service, which clears a surprising number of post-update glitches. Go back to any app, tap into a text field, and look for the mic button on the bottom row of the keyboard.
2. Check Microphone Permissions
Dictation cannot hear you if the microphone is blocked. iOS updates sometimes reset per-app and system microphone permissions, and a privacy review prompt you tapped through quickly may have switched something off.
- Go to Settings → Privacy & Security → Microphone.
- Make sure the apps you dictate in have microphone access enabled.
- If you use a third-party keyboard, that keyboard also needs microphone access, which is granted separately (see fix 8).
While you are in privacy settings, check that nothing is physically covering the bottom microphone of your iPhone. A thick case or a screen-protector film that overlaps the mic port can muffle input enough that dictation hears silence and gives up.
3. Restart Your iPhone
It sounds almost too simple, but a clean restart resolves a large share of post-update issues because it clears the temporary state that updates leave behind. A reboot reinitializes the audio subsystem and the keyboard services together.
Power your iPhone fully off, wait about thirty seconds, then turn it back on. Do not just lock the screen. A real shutdown-and-restart is what flushes the stale processes. Test dictation again before moving on.
4. Force-Quit and Reopen the App You're Dictating In
If dictation works in Notes but not in, say, your email or messaging app, the problem is likely that one app's text field, not the system. Swipe up from the bottom (or double-click Home on older models) to open the app switcher, swipe the affected app fully off the top of the screen to quit it, then reopen it. The app rebuilds its keyboard connection from scratch.
5. Check Screen Time Restrictions
Screen Time can disable dictation entirely, and a restored backup or a family-sharing change during the update can switch this restriction on without you realizing it. A greyed-out or missing mic button very often traces back to here.
- Open Settings → Screen Time.
- Tap Content & Privacy Restrictions.
- If restrictions are on, tap into them and make sure dictation and the microphone are allowed under the relevant categories.
If you do not use Screen Time, confirm the master Content & Privacy Restrictions toggle is off. This single setting blocks dictation more often than people expect, especially on phones set up for kids or managed by an employer.
6. Verify Your Dictation Language
iOS 18 can reset your dictation language to the system default, which is why some people suddenly find dictation typing in the wrong language or refusing to recognize their words at all.
- Go to Settings → General → Keyboard.
- Tap Dictation Languages.
- Make sure the language you actually speak is selected. Add it if it is missing.
If you speak more than one language, having several selected is fine, but the recognizer has to guess which one you are using, which lowers accuracy. If your dictation keeps guessing wrong, our guide on voice to text on iPhone walks through how multilingual setups behave and how to keep them from fighting each other.
7. Check Your Internet Connection
The built-in dictation feature leans on a network connection for its more accurate results. On a weak or captive Wi-Fi network (the kind that wants you to log in through a browser), dictation can hang silently. Try this:
- Toggle Airplane Mode on for five seconds, then off, to force a fresh network handshake.
- Switch from Wi-Fi to cellular (or vice versa) and test again.
- If you are on public or office Wi-Fi, confirm you have actually passed the login page.
If dictation works on cellular but not Wi-Fi, the problem is your network, not your phone, and you can fix it at the router or by reconnecting.
8. Re-Add Your Keyboard and Grant Full Access
If you rely on a third-party keyboard, iOS 18 may have reset its permissions. Third-party keyboards need Allow Full Access turned on to use their own dictation and to reach the microphone. Updates frequently revoke this.
- Go to Settings → General → Keyboard → Keyboards.
- Tap your keyboard and make sure Allow Full Access is on.
- If it still misbehaves, remove the keyboard and add it back. This rebuilds its extension cleanly.
A keyboard that has lost Full Access will often show a mic button that does nothing when tapped, which is one of the more confusing symptoms because everything looks normal until you press it.
9. Update Your Apps
A major iOS release sometimes lands before third-party apps have caught up. If dictation fails only in one specific app, an outdated version of that app may be incompatible with the new system. Open the App Store, go to your account, and update everything pending. App makers usually ship compatibility fixes within days of a big iOS update.
10. Reset Keyboard Dictionary and Network Settings
If you have worked down to here and dictation still won't behave, a targeted reset clears corrupted state without wiping your data. Two resets are worth trying, in this order:
- Reset Keyboard Dictionary: Settings → General → Transfer or Reset iPhone → Reset → Reset Keyboard Dictionary. This clears learned-word state that can interfere with recognition.
- Reset Network Settings: same menu, choose Reset Network Settings. Because dictation depends on the network, a tangled network stack after an update can break it. You will need to re-enter Wi-Fi passwords afterward, so have them handy.
Neither reset deletes your photos, messages, or apps. They only clear the specific settings named.
11. Update to the Latest iOS 18 Point Release
Finally, if a bug genuinely shipped in the version you installed, the fix is often a point update away. Go to Settings → General → Software Update and install any pending iOS 18.x release. Apple routinely patches feature regressions in the weeks after a major version, and dictation issues that affect many users tend to get addressed quickly.
When the Built-In Mic Keeps Letting You Down
Work down that list and you will fix the large majority of post-update dictation problems. But there is a category of complaint that no toggle resolves, because it is baked into how the built-in feature is designed rather than broken by an update:
- It cuts off when you pause to think, forcing you to start over.
- It never learns your vocabulary — names, jargon, and product terms come out wrong every single time.
- There is no way to fix a mistake by voice; you have to stop, tap, and edit by hand.
- It feels inconsistent across apps, working in one and stumbling in another.
If those are your real frustrations, re-enabling a toggle won't help, because the limitation is the tool itself. This is exactly the gap we built Voice Keyboard Pro to close. On iPhone, it is a custom keyboard with its own built-in mic button, so you can dictate in any app the same way you would with the stock keyboard, but with a transcription engine that keeps up with how people actually talk: pauses included, vocabulary remembered, and punctuation handled for you.
Two features in particular solve the complaints above. Voice Edit lets you fix text by speaking the change ("make that a question," "delete the last sentence") instead of poking at a cursor. And because the keyboard carries a personal dictionary with replacement rules, the names and terms the built-in feature keeps mangling get spelled the way you want, automatically. If you want the full picture of how a dedicated keyboard differs from the stock mic, our breakdown of the Apple Dictation alternative that works better covers the design decisions in detail.
How to Set It Up in About a Minute
Switching to a dedicated voice keyboard takes roughly the same time as one of the troubleshooting steps above:
- Install Voice Keyboard Pro from the App Store.
- Go to Settings → General → Keyboard → Keyboards → Add New Keyboard and select it.
- Tap the keyboard's name and turn on Allow Full Access so it can use the microphone.
- In any app, tap the globe key to switch to it, then tap the mic and start talking.
That is the same Full Access step from fix 8, which means if you have already done your troubleshooting, you are most of the way there. Our walkthrough of the iPhone keyboard with a built-in mic button shows the setup screen by screen if you want to follow along.
A Note on Privacy
People understandably get nervous about granting Full Access to a keyboard. Worth knowing: Voice Keyboard Pro's servers store only operational pings, the lightweight signals needed to keep the service running. We do not store your audio or the text you dictate. The words you speak go where you sent them and nowhere else.
Frequently Asked Questions
Why did my iPhone dictation stop working right after updating to iOS 18?
Major updates frequently reset toggles and permissions. The most common culprits are the Enable Dictation switch being turned off, microphone access being revoked, or a Screen Time restriction being switched on. Working through fixes 1, 2, and 5 above resolves the overwhelming majority of cases.
Is my microphone broken if dictation doesn't work?
Almost certainly not. Test the microphone by recording a Voice Memo or making a call. If those capture your voice clearly, the hardware is fine and the problem is a software setting. If they sound muffled too, check for a case or film covering the mic port.
Why does dictation cut off when I pause?
The built-in dictation feature stops listening after a short silence by design. It is not a bug you can fix in Settings. A dedicated keyboard like Voice Keyboard Pro is built to tolerate the natural pauses in real speech, so you can think mid-sentence without it quitting on you.
Does dictation work without an internet connection?
The built-in feature relies on a network connection for its more accurate results, so a weak or captive Wi-Fi connection can make it hang. Toggling Airplane Mode or switching to cellular often clears it.
Will resetting my keyboard dictionary delete my data?
No. Reset Keyboard Dictionary only clears learned-word suggestions. It does not touch your photos, messages, contacts, or apps.
The Bottom Line
If iPhone dictation stopped working after the iOS 18 update, start with the basics: re-enable dictation, confirm microphone access, and rule out a Screen Time restriction. Those three checks fix most cases in under two minutes. Restart, force-quit the affected app, verify your language, and check your network for the rest. And if the deeper problem is that the built-in feature cuts you off, forgets your vocabulary, and offers no voice-driven way to fix mistakes, that is a limit of the tool rather than a glitch to patch. A dedicated voice keyboard is the lasting fix. Voice Keyboard Pro has a free tier, so you can add it, grant Full Access, and dictate your next message without fighting a toggle ever again.
