/l/
在元音後（在詞尾）有兩種發法，第一種是你在單詞中的讀法，舌尖不抵住上齒齦；第二種是：
- The tongue tip and a portion of the tongue blade contact the alveolar ridge in the midline
舌尖抵住上齒齦或上牙，兩門牙中間，（舌麵不要平鋪，要變成細舌）。
- Lip configuration may vary depending on phonetic context
嘴唇不要變化 （尤其不要前突）。
- The vocal folds are abducted and vibrating
- The velopharyngeal port is closed
- Acoustic energy radiates laterally, around midline closure
-
/r/
- The tongue is elevated towards the hard palate in a bunched configuration
- The front of the tongue is usually close to the alveolar ridge but may be retroflexed.
- The lips are slightly unrounded
- The vocal folds are abducted and vibrating
- The velopharyngeal port is closed
