日语基础语音（Basic Japanese pronunciation） vowel The definition of 1. vowels and the characteristics of Japanese vowels The general definition of vowels is that the vocal cords vibrate and the airflow is unimpeded by the passage of the mouth. Although the flow in the vowel unhindered in the oral pathway, but the mouth (including mandibular opening, lip and tongue Exhibition Park) (including tongue height, anteroposterior position) subtle changes will make the vowel sound change subtly. Unlike Chinese, which has many compound vowels, the 5 vowels in Japanese are all units. The characteristic of a unit tone is that the position of the vocal organ (including the mouth shape and tongue position) should be stabilized during the pronunciation, and the shape of the vocal tract can not be changed midway. In Japanese, even when the two vowels are connected, they are also distinct. For example, Chinese Grandpa in Ye, because of the mouth and tongue position from [i] to [e] so that the whole syllable tone sliding, gradual change, thus the boundary between [i] and [e] is vague; and the Japanese live in the opposite forms, from [i] to [e] but not sliding transients. In addition, the stability of the Japanese vowel is also manifested in: no matter how the phonetic environment changes (i.e., no matter what comes before or later), the vowel itself has no significant change in timbre. For example, the timbre of Chinese a is different in the phonetic environment of an, Yan and Yang. They are respectively the first low vowel, the first half low vowel and the latter low vowel. Japanese vowels maintain a relatively stable tone in any phonetic environment without any significant change in tone. Comparing the Japanese and Chinese vowel and tongue bitmap, we can see that the reason for the Japanese is that the mandibular opening is not big, and the range of tongue position is less than that of chinese. Therefore, when speaking Japanese, the opening and closing of the mouth and the movement of th
