-<li><strong>Diphthong Preservation:</strong> Unlike Inner Mongolian dialects which monophthongize sounds, Halh
-    preserves diphthongs (e.g., <code>ай</code> becomes <code>/ai/</code>, not <code>/ɛː/</code>).
-</li>
-<li><strong>Nasal Assimilation:</strong> The dental nasal <code>н</code> assimilates to the velar nasal <code>/ŋ/</code>
-    before velar consonants (<code>г, к, х</code>) and at the end of words.
-</li>
-<li><strong>Syllable Coda Glides:</strong> The letter <code>в</code> in a syllable coda (end of a syllable) is
-    realized as the glide <code>/w/</code> rather than a fricative.
-</li>
-<li><strong>Palatalization:</strong> Consonants are automatically palatalized in specific contexts, notably the
-    fricative <code>ш</code> becoming <code>/ɕ/</code> before <code>i</code>.
-</li>
-<li><strong>Absence of Stress:</strong> Following Svantesson (2005), word stress is considered non-phonemic in
-    Mongolian. Therefore, no stress marks (<code>ˈ</code>) are generated.

-    Mongolian pronunciation module</a>, but has been modified to adhere to the phonological analysis in <em>The
-    Phonology of Mongolian</em> (Svantesson et al., 2005). Key modifications include:</p>
-<ul>
-    <li><strong>Stress Removal:</strong> The logic for generating phonemic stress marks was removed, as stress is
-        non-contrastive in Mongolian.
-    </li>
-    <li><strong>Schwa Generation:</strong> A syllable-aware processing loop was added to correctly reduce
-        non-initial short vowels to <code>/ə/</code> while preserving full vowels in the initial syllable.
-    </li>
-    <li><strong>Dialect Correction:</strong> Vowel mappings were adjusted to reflect Standard Halh (Ulaanbaatar)
-        rather than Chahar/Inner Mongolian (e.g., restoring diphthongs and the initial <code>э/и</code> merger).
-    </li>
-</ul>
