<h2>1. Read the Verse</h2>
|
| 59 |
-
<p>
|
| 60 |
-
The user is shown a <strong>Reference Verse</strong> in Arabic script along with its corresponding <strong>Reference Phoneme Sequence</strong>.
|
| 61 |
-
</p>
|
| 62 |
-
<p><strong>Example:</strong></p>
|
| 63 |
-
<ul>
|
| 64 |
-
<li><strong>Arabic:</strong> إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ</li>
|
| 65 |
-
<li>
|
| 66 |
-
<strong>Phoneme:</strong>
|
| 67 |
-
<code>< i n n a SS A f aa w a l m a r w a t a m i n $ a E a a < i r i l l a h i</code>
|
| 68 |
-
</li>
|
| 69 |
-
</ul>
|
| 70 |
-
|
| 71 |
-
<h2>2. Save Recording</h2>
|
| 72 |
-
<p>
|
| 73 |
-
The user recites the verse aloud; the system captures and stores the audio waveform for subsequent analysis.
|
| 74 |
-
</p>
|
| 75 |
-
|
| 76 |
-
<h2>3. Pronunciation Assessment</h2>
|
| 77 |
-
<p>
|
| 78 |
-
The stored audio is fed into a <strong>Mispronunciation Detection Model</strong>.
|
| 79 |
-
This model aligns the user’s pronunciation with the <em>Reference Phoneme Sequence</em> to detect any mismatches.
|
| 80 |
-
</p>
|
| 81 |
-
<p><strong>Example of Mispronunciation:</strong></p>
|
| 82 |
-
<ul>
|
| 83 |
-
<li><strong>Reference Sequence:</strong> <code>... m i n $ a E a a < i r i l l a h i</code></li>
|
| 84 |
-
<li><strong>User’s Pronunciation:</strong> <code>... m i n s a E a a < i r u l l a h i</code></li>
|
| 85 |
-
<li>
|
| 86 |
-
<strong>Annotated Feedback:</strong>
|
| 87 |
-
<code>... m i n <span class="highlight">s</span> a E a a < i <span class="highlight">r u</span> l l a h i</code>
|
| 88 |
-
</li>
|
| 89 |
-
</ul>
|
| 90 |
-
<p>
|
| 91 |
-
In this case, the phoneme <code>$</code> was mispronounced as <code>s</code>, and <code>i</code> was mispronounced as <code>u</code>.
|
| 92 |
-
</p>
|
| 93 |
-
|
| 94 |
-
<h2>4. Feedback</h2>
|
| 95 |
-
<p>
|
| 96 |
-
The system generates an <strong>Annotated Verse</strong> and phoneme‐level feedback.
|
| 97 |
-
Mispronunciations are highlighted (for example, in red) to help the user identify and correct their errors.
|
| 98 |

<h2>Task Description: Quranic Mispronunciation Detection System</h2>
|
| 46 |
|
| 47 |
+
<p>
|
| 48 |
+
The aim is to design a model to detect and provide detailed feedback on mispronunciations in Quranic recitations.
|
| 49 |
+
Users read aloud vowelized Quranic verses; This model predicts the phoneme sequence uttered by the speaker, which may contain mispronunciations.
|
| 50 |
+
Models are evaluated on the <strong>QuranMB.v2</strong> dataset, which contains human‐annotated mispronunciations.

<h3>1. Read the Verse</h3>
|
| 59 |
+
<p>
|
| 60 |
+
The user is shown a <strong>Reference Verse</strong> in Arabic script along with its corresponding <strong>Reference Phoneme Sequence</strong>.
|
| 61 |
+
</p>
|
| 62 |
+
<p><strong>Example:</strong></p>
|
| 63 |
+
<ul>
|
| 64 |
+
<li><strong>Arabic:</strong> إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ</li>
|
| 65 |
+
<li>
|
| 66 |
+
<strong>Phoneme:</strong>
|
| 67 |
+
<code>< i n n a SS A f aa w a l m a r w a t a m i n $ a E a a < i r i l l a h i</code>
|
| 68 |
+
</li>
|
| 69 |
+
</ul>
|
| 70 |
+
|
| 71 |
+
<h3>2. Save Recording</h3>
|
| 72 |
+
<p>
|
| 73 |
+
The user recites the verse aloud; the system captures and stores the audio waveform for subsequent analysis.
|
| 74 |
+
</p>
|
| 75 |
+
|
| 76 |
+
<h3>3. Mispronunciation Detection</h3>
|
| 77 |
+
<p>
|
| 78 |
+
The stored audio is fed into a <strong>Mispronunciation Detection Model</strong>.
|
| 79 |
+
This model predicts the phoneme sequence uttered by the speaker, which may contain mispronunciations.
|
| 80 |
+
</p>
|
| 81 |
+
<p><strong>Example of Mispronunciation:</strong></p>
|
| 82 |
+
<ul>
|
| 83 |
+
<li><strong>Reference Sequence:</strong> <code>... m i n $ a E a a < i r i l l a h i</code></li>
|
| 84 |
+
<li><strong>User’s Pronunciation:</strong> <code>... m i n s a E a a < i r u l l a h i</code></li>
|
| 85 |
+
<li>
|
| 86 |
+
<strong>Annotated Feedback:</strong>
|
| 87 |
+
<code>... m i n <span class="highlight">s</span> a E a a < i <span class="highlight">r u</span> l l a h i</code>
|
| 88 |
+
</li>
|
| 89 |
+
</ul>
|
| 90 |
+
<p>
|
| 91 |
+
In this case, the phoneme <code>$</code> was mispronounced as <code>s</code>, and <code>i</code> was mispronounced as <code>u</code>.
|
| 92 |
+
