Pronunciation law of nasal edge sounds n and l

1, the edge sound l, when pronounced, the tip of the tongue is close to the back of the upper gum, forming obstruction; The soft palate rises, blocking the nasal passage and vibrating the vocal cords; When the airflow reaches the mouth, it passes through the gap between the sides of the tongue and the inside of the cheek, forming sound.

To sum up: the tongue is flat, the tip of the tongue touches the gum, and the tongue is flat and contracted when pronounced. When spreading and contracting, the tongue surface should be as flat as possible, and the tongue should not protrude to block the mouth. All the air flows out from both sides of the tongue, and then the tip of the tongue bounces off gently, making a sound. The nose does not participate in pronunciation, so the timbre is crisp.

2, nasal N, when pronouncing, the tip of the tongue and the two sides of the front of the tongue are completely closed with the front upper part of the mouth, and then the tip of the tongue abuts against the upper gum to form an obstruction; The soft palate descends and the nasal passages are opened; The airflow reaches the oral cavity and nasal cavity at the same time, and is blocked in the oral cavity, and the airflow comes out of the nasal cavity and becomes sound.

When pronouncing N, the tip of the tongue should be pressed against the upper gum, and then the nose will vibrate when pronouncing. At this time, when the airflow pushes on the nose, N sounds will be made by nasal sounds.
