Sometimes Tarteel flags a mistake on a word you recited correctly, or accepts a word you recited with a mistake. This happens in recitation, memorization and tests. This article explains why this happens, how to get more accurate results, what to send us if the same word is affected every time, and how to remove a wrongly flagged mistake so it doesn't count against your score.
Why Tarteel Flags a Mistake You Did Not Make
Tarteel recognizes your recitation live from your microphone, so anything that muddies the audio can cause a wrong flag. The common causes are:
Background noise: traffic, fans, appliances, or people talking nearby.
Background speech in the room: a TV, radio, or someone else reciting can be picked up as part of your recitation.
Car or Bluetooth microphones: these often compress audio and pick up road noise, which makes recognition less accurate.
Tajweed rules: Tarteel does not check tajweed rules yet, so a tajweed rule is never the reason for a flag.
Tashkeel detection: when the setting Detect Tashkeel (diacritics) mistakes is on, Tarteel also flags diacritical mistakes. If you want word-level detection only, turn it off under Settings, then Recitation, under Mistake Detection.
The model's own limits: recognition is very good but not perfect, and an occasional wrong flag can happen even in a clean setup. Madd Lazim for example is something our model does not recognize well all the time and is something we are working on improving.
How to Reduce Wrong Flags
A clean setup reduces wrong flags in every mode:
Recite in a quiet room, away from other voices and screens playing audio.
Use your phone's built-in microphone rather than a Bluetooth headset or car system.
Keep the phone within comfortable reach. You don't need to hold it to your mouth, but don't leave it across the room.
Recite clearly at your natural pace.
Tarteel Did Not Catch a Mistake I Made
Sometimes Tarteel accepts a word as correct when you recited it with a mistake, for example a letter that sounds close to the right one. This can happen in recitation, memorization and tests. The causes are the same as for wrong flags: background noise, a Bluetooth or car microphone, and the model's own limits. Tarteel does not check tajweed rules yet, so a tajweed mistake is never flagged.
To help Tarteel catch more of your mistakes:
Check that Detect Mistakes is on under Settings, then Recitation.
Recite in a quiet room, away from other voices.
Use your phone's built-in microphone rather than a Bluetooth headset or car system.
Recite clearly at your natural pace.
If Tarteel misses the same mistake in the same ayah every time, contact our support team and share a screen recording with sound of that ayah.
Stuck on One Word While Reciting
If Tarteel holds you on one word while reciting, the setting Don't progress until mistake is fixed is on. Turn it off under Settings, then Recitation, under Mistake Detection, to continue past a wrong flag.
How to Remove a Wrong Flag
A wrong flag can be removed so it does not count in your Mistake History, your highlights or your test score. Tap the highlighted word, then tap the remove icon. For every way to remove a mistake, including from a session's mistakes list or later from Activity, and how to put one back, see the article How to remove a mistake.
The Same Word Is Flagged Every Time
If Tarteel flags the same word or verse every time you recite it correctly, contact our support team and share a screen recording of the mistake in question.
