Why Does the Duolingo App Have No Sound?
Duolingo going silent is usually a setting inside the app rather than a broken speaker, because Duolingo keeps its own sound switches separate from your phone’s volume. The lesson audio, the sound effects, and the speaking exercises each have their own controls, and any one of them can go quiet while the rest of the phone works fine.
Is the Sound Off Inside Duolingo, or Is the Phone Silent?
First, check the sound-effects toggle inside the app. Open Duolingo, tap your profile icon, then the settings gear, and look for the sound effects option. If it is switched off, the cheerful dings and wrong-answer buzzes disappear — and many people mistake that for the whole app being silent, even though the lesson audio is a separate thing.
Next, start a lesson and listen for the spoken sentences. If the sound effects are on but the spoken words are missing, the problem is with lesson audio, not with the effects toggle. If neither makes a sound, check the phone itself: press volume-up while a lesson is open and watch the on-screen volume bar. Duolingo uses the media volume, so if the media volume is down, the app stays quiet even when the ringtone volume is up.
Also try another app with sound. If a video plays normally, the silence belongs to Duolingo; if nothing plays, jump to the speaker check at the end.
Why Do Speaking Exercises Stay Silent?
Speaking exercises are the part of Duolingo most likely to go quiet, and they fail for a different reason from the rest of the app: they need the microphone. If Duolingo does not have microphone permission, a speaking exercise may show no sound, refuse to record, or sit there with a spinning indicator while the rest of the lesson works.
On iPhone, go to Settings, then find Duolingo in the app list, and make sure the microphone switch is on. On Android, go to Settings, then Apps, then Duolingo, then Permissions, and allow the microphone. Then force-close Duolingo and open it again, because a permission changed while the app is running often does not take effect until the app restarts.
If the microphone is allowed and speaking exercises still fail, check whether the phone is connected to Bluetooth earbuds or a car system. The exercise may be listening through a device that is in another room or switched off. Turn Bluetooth off and try the exercise again on the phone speaker.
One more quirk: some exercises will not play their prompt audio if the phone is on silent mode. On iPhone, flip the silent switch off; on Android, check Do Not Disturb is not silencing media audio.
The Lesson Audio That Plays Everywhere Except Duolingo
A common complaint is that lesson audio works in every other app but not in Duolingo. When that happens, the cause is usually Duolingo’s own audio session getting stuck. The app holds the audio channel open while a lesson runs, and if something interrupts it — a phone call, an alarm, another app playing a notification sound — the channel can stay locked in a silent state.
Force-close Duolingo completely, not just back out to the home screen. On iPhone, swipe the Duolingo card away; on Android, swipe it away in the recent-apps view. Then reopen the app and start a fresh lesson — a half-finished lesson resumed from the same broken session will often stay silent.
Offline Lessons and the Download That Never Finished
Downloaded lessons are a frequent source of silence in Duolingo. An offline lesson that was downloaded on weak Wi-Fi, or interrupted when the phone went to sleep, can end up with its audio files missing. The lesson text loads fine, because that part downloaded correctly, but the spoken sentences have nothing to play.
The tell-tale sign is that online lessons have sound and offline lessons do not. Test a lesson on Wi-Fi: if the audio returns, the offline copy is the problem. Delete the downloaded lesson data and download it again on a stable connection.
Storage matters here too. If the phone is nearly full, Duolingo may fail to finish downloading the audio files. Free up space, then re-download the lesson — a lesson downloaded months ago can also go stale after an app update changes the audio format.
Cache, Updates, and When to Reinstall
When the toggles are right, the microphone is allowed, and the lessons are fresh, the app’s own temporary data is the next suspect. On Android, go to Settings, then Apps, then Duolingo, then Storage, and tap Clear Cache. Your streak, progress, and XP live on your Duolingo account, so clearing the cache does not touch them — it only removes the temporary files that may have gone bad.
On iPhone there is no cache button, so force-close the app and restart the phone instead — a restart clears the same kind of stuck audio state.
Then check for an app update. Audio bugs are a common thing for updates to fix, and a version of Duolingo that is a few releases behind can clash with a newer phone system. Update the app, restart the phone, and test a lesson you know was silent before.
If the silence survives all of that, delete Duolingo and reinstall it. Sign back into the same account and your progress, streak, and leagues come back with it. A fresh install clears corrupted settings that a cache clear cannot reach. Re-download any offline lessons afterwards.
Testing the Speaker Itself
If every app is quiet, not just Duolingo, the speaker is the prime suspect. Check the speaker grille is not blocked by a case, pocket lint, or dust — a soft, dry brush can clear debris that is muffling the sound, and taking the case off for a test rules out a case pressing on the grille.
Water is a frequent cause, especially after rain, a splash, or a steamy bathroom. The free speaker-cleaner tool on this site plays a tone designed to push water and dust out of the speaker — run it a couple of times and try a Duolingo lesson again.
Also test with headphones. If Duolingo has sound through earbuds but not through the phone speaker, the app settings are fine and the fault is in the speaker hardware. If headphones are silent too, and every app is silent, the phone’s audio system needs a restart or a repair.
Frequently Asked Questions
Why does Duolingo have no sound in lessons?
Check the sound-effects toggle and the phone’s media volume, then force-close the app and start a fresh lesson. A stuck audio session from an interrupted lesson is the most common cause.
Why won’t Duolingo speaking exercises work?
They need microphone permission. Allow the microphone in your phone settings for Duolingo, force-close the app, and reopen it. Also turn Bluetooth off, since the exercise may be listening through earbuds elsewhere.
Why do offline Duolingo lessons have no sound?
The lesson’s audio files may not have finished downloading. Test the same lesson on Wi-Fi, then delete and re-download the offline lesson on a stable connection.
Will reinstalling Duolingo delete my streak?
No. Your streak, XP, and progress live on your Duolingo account, so they come back when you sign in again. You will need to re-download offline lessons afterwards.
