What it does
- Word-by-word following while the user recites, flagging missing, swapped or skipped words.
- Tajweed notes, clearly marked as notes that may be wrong.
- Tests by voice or multiple choice, with spaced repetition.
- My Mistakes: a list of words the user got wrong, which stay until they are recited correctly three times in a row.
- Find a verse by voice from a few spoken words.
Why on-device
Recitation is personal, and people practise anywhere. Running recognition on the phone means it works with no connection, answers without a server round trip, and keeps the recording on the device.
Engineering notes
Following, not transcribing
The app knows the text the user is reciting. The hard part is aligning what the recogniser hears with that text as the user speaks, and staying on track after a mistake, a repeat or a skipped verse.
Tested with mistakes
Changes to the matching logic are tested on recordings that contain deliberate errors, such as a forgotten verse or a wrong word, and compared against the previous version on the same recordings before release.
