The difference between vowel o and uo.

First of all, the pronunciation is different

1, vowel o: when pronouncing, the mouth is half closed, the lips are round, the tongue is retracted, the back of the tongue is slightly warped, and the vocal cords vibrate after the gums are placed on the tip of the tongue. The soft palate rises, closing the nasal passages.

2. Vowel uo: When pronounced, the initial vowel o is slightly higher than the tongue position of the single vowel o [o], and the lip shape is slightly round. When pronouncing, the initial o [o] is clear and loud, the tongue slides in the direction of U, and the pronunciation of U [u] is vague, which only indicates the direction in which the tongue slides. Ou is the shortest compound vowel in Putonghua.

Second, different ownership.

1, vowel o: vowel, also known as vowel.

2. Vowel uo: A vowel composed of two or three vowels, belonging to a compound vowel.

Extended data

The parts of Chinese pronunciation except initials and tones. Formerly known as rhyme Vowels can be divided into three parts: the beginning (middle tone), the abdomen (main vowel) and the end. For example, the vowel of "Niang" niáng is iang, where I is rhyme, α is rhyme and ng is rhyme.

Every vowel must have a rhyme belly, and the beginning and end of the rhyme are dispensable. For example, the vowel of "da" Dà is α, α is a rhyme belly, and there is no rhyme ending; The vowel of "gua" gu ā is ua, where U is rhyme, α is rhyme and there is no rhyme. The vowel of "Dao" Dā o is ao, where α is the rhyme belly and O is the rhyme ending, and there is no rhyme.

Vowel = vowel (middle tone)+vowel (vowel, the most critical part of vowel)+vowel (vowel can be consonant, where consonant refers to nasal vowel).

Vowels in syllables can usually be divided into three parts: rhyme head, rhyme belly and rhyme end. For example, in the syllable "Guan", "G" is the initial and "uan" is the final. In vowel [[『uan』]], [a] is an abdominal sound, [u] is the beginning and [n] is the end.

The rhyme head, also called the middle tone, is the leading part before the rhyme belly, with vague pronunciation and often passing quickly;

Rhyme belly, also known as the main vowel, is the key to vowel pronunciation and the most tense and loudest part of oral muscles in the process of vowel pronunciation.

The ending can be vowels and consonants. One is called nasal rhyme, which has -n and -ng. The other is called rhyming ending. The rhyme ending is the ending part behind the rhyme belly, and the pronunciation is vague, but it should be pronounced in place.

As far as the word "card" is concerned, q is the initial letter and ia is the vowel. I rhymes; A rhymes.
