Classification of Rhymes

1. Nasal rhymes are rhymes that end with a nasal sound, consisting of a main nasal sound and a nasal ending sound. In Mandarin, there are only two nasal endings: -n and -ng. The nasal ending of the first nasal consonant is -n, and the nasal ending of the second nasal consonant is -ng. So can you tell the difference between the first and second nasal consonants?

Front nasal: an en in un un

Back nasal: ang eng ing ong

2, front nasal, back nasal rhymes, where n is pronounced with the tip of the tongue playing a major role, so the rhymes with n are called front nasal rhymes; ng is pronounced with the root of the tongue playing a major role, so the rhymes with n are called back nasal rhymes.

When pronouncing an anterior nasal consonant, the mouth is closed, i.e., the opening is small; the sound is dull, thin, and small. When pronouncing a postnasal consonant, the mouth is slightly open, i.e., the opening is larger; audibly, the sound is louder, louder, and the ****ing is stronger.

3, the pronunciation of nasal consonants is difficult to distinguish between the "-n" in the front nasal consonants and "-ng" in the back nasal consonants, which are only followed in the syllable in one or two vowels followed by a rhyming ending.

As the name suggests, the difference is that the tip of the tongue acts against the upper gums when pronouncing nasals, while the root of the tongue acts against the soft palate (the upper part of the mouth is the hard palate, the back is the soft palate, and the back is the uvula) when pronouncing velars. When pronouncing, if you place your thumb and index finger around the bridge of your nose, you will feel a vibration.
