长度, 持续时间
the duration of a speech sound, whether it is a vowel or a consonant
Length, in the context of phonetics, refers to the duration or amount of time a sound is held during pronunciation. It can apply to both vowels and consonants, affecting the overall quality of speech. Long sounds are held for a greater duration than short sounds, which can change the meaning of words in some languages. For example, in Japanese, the difference between a short vowel sound and a long vowel sound can change a word's meaning, such as "biru" (beer) versus "biiru" (building). Understanding length is important for accurate pronunciation and comprehension in various languages.
