一、嗓音的生理 在教师的教学过程中,声音和语音至关重要。喉是发声的重要器官。在发声前,声带需格近中线。发声时,需要声带保持一定的张力,并在二者之间形成一裂隙。当空气从肺部呼出,通过声门裂冲击声带时,就发出声音,称为基音。再经过喉腔、咽腔和鼻腔的共鸣作用,经舌、腭、齿、唇及有关结构在神经系统协调下运动,才发出各种声音和语音。 鼻腔的功能主要为呼吸、嗅觉和共鸣作用。它对吸入的空气有过滤清洁、温度和湿度的调节作用。如 First, the voice of the physiology Teachers in the teaching process, voice and voice are crucial. Throat is a vital organ of vocalization. Before vocalization, the vocal cord needs to be nearly neutral. When vocalizing, the vocal cords are required to maintain a certain tension and form a gap between the two. When air exhales from the lungs and strikes the vocal cords through the glottis, it sounds, called the pitch. And then through the throat, pharynx and nasal resonance, through the tongue, palate, teeth, lips and related structures in the nervous system under the coordination of movement, before making a variety of sounds and voices. Nasal function is mainly respiratory, olfactory and resonance. It has filtered air inhaled clean, temperature and humidity regulation. Such as
