<h2>Pronunciation and Phonetics</h2>
<p><strong>Definition:</strong> Pronunciation is the way in which words and phrases are spoken, while phonetics is the study of speech sounds.</p>
<h3>Key Concepts:</h3>
<ul>
<li><strong>Vowels:</strong> Vowels are produced with an open vocal tract. They can be categorized based on their position in the mouth.</li>
<li><strong>Consonants:</strong> Consonants are produced by blocking or partially blocking the airflow in the vocal tract. They can be classified by place and manner of articulation.</li>
</ul>
<h4>Vowel Sounds</h4>
<p>Vowels can be divided into two main categories: monophthongs (single vowels) and diphthongs (two vowel sounds combined).</p>

<h4>Consonant Sounds</h4>
<p>Consonants can be classified by the place of articulation (where in the mouth the sound is made) and the manner of articulation (how the sound is produced).</p>

<tr>
<th>Place of Articulation</th>
<th>Manner of Articulation</th>
<th>Examples</th>

<tr>
<td>Bilabial</td>
<td>Plosive</td>
<td>/p/, /b/</td>
