青春期孩子的嗓音由清脆、稚气的童声向成人嗓音转变,这个时期叫做“变声期”。一般来说,这时儿童嗓音变得怎样,决定着一生嗓音的好坏。要了解孩子是否进入变声期,一要看年龄,二要看性别(男孩子多在12～14岁,女孩子多在12岁开始),三要看声音,这是关键的一条。如果孩子处在变声期,说话嗓音发哑,唱歌时声音上不去,检查声带发现有充血,这说明孩子已进入了变声期。 The voice of adolescent children from crisp, childish voice to adult voice change, this period is called “changing voice period.” In general, when the child’s voice becomes what determines the voice of his life. To understand whether the child into the vocal period, one depends on the age, two depends on gender (boys are mostly in 12 to 14 years old, girls are mostly in 12 years old), three to see the sound, this is the key one. If the child is in a changing vocal phase, his voice is dumb, the voice does not go up while singing, and the vocal cord is found to have congestion. This shows that the child has entered the vocal period.
