You’re tapping the microphone key and… nothing. Or the words come out garbled, or the mic button is missing from the keyboard entirely. Dictation is one of those iPhone features you don’t appreciate until it breaks — and when it does, the cause is rarely obvious. The good news: it’s usually a settings hiccup, a corrupted language pack, or a restriction you forgot you enabled. Here are seven proven fixes, from quickest to most drastic.
How to fix Dictation not working on iPhone
Work through these in order:
- Restart your iPhone. The oldest trick fixes a surprising number of dictation glitches — a stuck speech service usually clears on reboot. Hold the side button and either volume button, slide to power off, wait about 30 seconds, and power back on.
- Toggle Dictation off and on. Go to Settings, then General, then Keyboard, and switch Enable Dictation off. Wait a few seconds and switch it back on. This re-registers the speech service and fixes the "mic button does nothing" case. Apple’s iPhone User Guide documents the Dictation settings officially.
- Delete and re-download dictation languages. Corrupted language packs are a classic cause. In Settings, go to General, then Keyboard, then Dictation Languages — remove your language and add it again to force a fresh download. 9to5Mac’s guide to dictating on iPhone has more tips for getting clean results once it’s working.
- Add a new keyboard language. Still in Keyboard settings, add another keyboard language and let its dictation data download. This refreshes the underlying speech data even for your primary language — odd, but it works.
- Check Screen Time restrictions. Go to Settings, then Screen Time, then Content & Privacy Restrictions, then Allowed Apps, and make sure Siri & Dictation is enabled. If someone — or you, long ago — disabled it here, the mic button vanishes entirely.
- Toggle Siri off and on. Dictation and Siri share the same plumbing. Go to Settings, then Siri (or Apple Intelligence & Siri on newer iOS), switch Siri off, restart the phone, and switch it back on.
- Reset all settings — or reinstall iOS. Last resort: go to Settings, then General, then Transfer or Reset iPhone, then Reset, and choose Reset All Settings. This keeps your data but returns every setting to defaults. If even that fails, reinstall iOS via a computer. Note: on-device dictation needs a compatible iPhone model, and some languages still require an internet connection.
If it still doesn’t work
If dictation works in some apps but not others, the app itself may simply not support the dictation keyboard — test in Notes as a baseline. Check you’re not on a VPN or a restrictive network that blocks Apple’s speech servers. And if the microphone works fine for calls but not dictation, it’s software, not hardware — don’t book a repair yet.

FAQ
Why is the dictation mic button missing from my keyboard?
Either Enable Dictation is switched off (Settings, then General, then Keyboard), or Screen Time restrictions have disabled Siri & Dictation. Check both — the button can’t appear while the feature is gated.
Does dictation work offline?
Partly — newer iPhones handle on-device dictation for many languages, but some languages and older models still need connectivity. If dictation fails in airplane mode, that’s expected behavior. While you’re exploring mic-powered tricks, you might also like how to automatically identify songs playing nearby on iPhone.
The bottom line
Dictation failures are almost always software: a toggle, a corrupted language pack, or a forgotten restriction. The restart-and-retoggle combo fixes most cases in under two minutes; the language re-download handles the stubborn rest.
