攻击, 声母
the initial sound or sounds of a syllable that come before the vowel, forming the beginning part of a syllable and can consist of one or more consonant sounds
An onset is the initial part of a syllable that comes before the nucleus, typically consisting of one or more consonant sounds. It serves as the opening of the syllable and can vary in complexity depending on the language. For example, in the word "cat," the onset is the "c" sound, while in "spring," the onset consists of the "spr" cluster. The onset is important in phonetics because it contributes to the overall structure of syllables and affects the pronunciation and flow of speech, influencing how words are articulated in different languages.
