5、guage came too late that there have hardly been any human organs evolving specifically for verbal articulation except the vocal cords thin bands of muscle in the larynx at the upper end of a persons windpipe that can be made to move rapidly by the passing of air and thus produce sound. Other organs

6、involved in the production of speech evolved originally for the basic biological needs of breathing and eating, though phoneticians also call them speech organs. Cavities and organs The principal cavities 1. the pharyngeal cavity （咽腔）（咽腔） 2. the oral cavity （口腔）（口腔） 3. the labial cavity （唇腔）（唇腔） 4.

7、the nasal cavity （鼻腔）（鼻腔） The vocal tract （聲道）（聲道） - the long tubular structure formed by the cavities， functioning as a resonance box. Changing the shape of the box gives different speech sounds.1.5 Diagram of the speech cavities1.6 Diagram of the speech organs氣管喉食道聲帶會厭咽舌根舌面軟腭小舌舌尖硬腭齒齦1.7 Consonants

13、y：The studies of the structure and systematic patterning of sounds in human language. The word phonology is used in two ways, either as the study of sound patterns in language or as the sound pattern of a language. Every consonant or vowel is the smallest unit of sound which can distinguish two word
