1. A compound vowel syllable refers to a vowel consisting of two or three vowels. For example, "ai" is a vowel, and its label is "a+i", where "A" is an initial and "I" is a vowel. There are two kinds of polyphony: binary polyphony and ternary polyphony. A disyllabic vowel consists of two vowels, such as ai, ei, ao, ou, ia, ie, ua, uo, üe, iao, iou, uai and uei.
2. Vowel pronunciation has two characteristics. First, there is no obvious boundary between vowels, and the whole pronunciation process is coherent and forms a whole. Second, polyphony has a beginning and an end. Take ai as an example. A is a vowel and I is a vowel. Pronunciation is coherent, not as obvious as single vowels.
3. The use of vowels can enrich language expression and make the language more vivid. For example, in poetry, lyrics, prose and other literary works, the author often uses vowels to enhance the expressive force and appeal of the language. In oral communication, proper use of vowels can also make the language more fluent and natural.
Information about syllables
1, syllable is the basic unit of Chinese phonetic structure and the smallest phonetic fragment that people can perceive naturally. A Chinese character usually corresponds to a syllable, and Chinese characters are also called "syllable words". When learning Chinese, we need to master the corresponding syllable rules according to the specific language environment.
2. Syllables are composed of initials, finals and tones. Initial is a consonant at the beginning of a syllable, vowel is a vowel in a syllable or a combination of vowels and consonants, and tone is a symbol indicating pitch change. For example, in the syllable "ma", "M" is the initial and "A" is the final, without tone.
3. Chinese has many syllables, * * * with 1300 different syllables. There are complex relationships between these syllables, including the same initial, the same vowel and the same tone. Mastering these relationships is very important for learning Chinese pronunciation and pinyin. There are also many different syllable systems in Chinese dialects. Cantonese has six tones and Shanghai dialect has eight tones.
