The characteristics of vowels in Shandong Gaoqing dialect include, compared with Mandarin, the tongue tip vowel is biased towards the middle, and the central vowel is biased towards the lower back. The tongue positions of ɛ and ɔ are close to y and u, respectively. ɛ is already a monophthong, while ɔ still has the color of the compound sound αu. Although Iə, uə, and yə are all derived from increased or weakened sounds, there are gradient differences in the size, sliding coherence, and duration of the influence of finals. The compound vowels of “ei” and “zhongxiang” have weak vowel sounds. When u is used as the initial phoneme of a vowel, the trajectory of the movement often has corners. The internal synergistic pronunciation effect of iα and iɛ is significant. The nasalized monophthong often serves as the main component in nasalized vowels. The movement of the posterior nasal vowels is complex and often unstable.展开更多
