所谓变声期是13——15岁时由于喉腔前后径变宽,声带增长、增厚和增宽,致使原来清脆、甜美、明亮的童声变为低沉深厚的成人声。变声期持续的时间大约半年,也有少数长达一年之久的。其间许多孩子往往会觉得失去控制和支配噪音的能力,发音时感到力不从心,不听使唤,发高音更觉困难。发音不稳定、沙哑,常常会出现一种难听的怪声。如果强唱势必损伤声带。 The so-called changing voice period is 13--15 years old as the throat before and after the widening path, vocal cords grow thickening and widening, resulting in the original crisp, sweet, bright children’s voice into a deep, deep adult voice. Variable voice period lasts about six months, but also a few as long as a year. In the meantime, many children often feel that they have lost the ability to control and dominate the noise. They feel powerless when they pronounce their words, and do not listen to them and make loud voices more difficult. Unstable pronunciation, hoarseness, often a strange noise. If the singing is bound to damage the vocal cords.
