Verbal 自16世纪以来一直为优秀作家所使用，用来指与书面交流相对的口头交流， 而且不能认为这一用法是不正确的。但是批评家们却正确地评论说verbal 的这一用法有些时候可能会与意指“通过语言的方式”的用法相混淆。 由此modern technologies for verbal communication（用于语言交流的现代技术） 这一短语可能只用于指诸如无线电广播、电话以及扬声器之类的装置， 或者也有可能又指诸如电报机、电传打字机以及传真机之类的装置。在这种情况中，oral 一词总是用来表示用口头方式的狭义上的交流 〔armature〕The moving part of an electromagnetic device such as a relay, buzzer, or loudspeaker.电枢：电磁装置的移动部分，如继电器，蜂音器或扬声器〔multidirectional〕a multidirectional television antenna; multidirectional stereo speakers.多方向的电视天线；立体声扬声器〔monitor〕A receiver, such as a screen or speaker, that is used to check the quality or content of an electronic transmission:接受器，屏幕，扬声器：用来检查无线电广播的质量和内容的一种接收器，如屏幕或扬声器，：〔woofer〕A loudspeaker designed to reproduce bass frequencies.低频扬声器：设计用来再现低音频率的扬声器〔diffuser〕A device, such as a cone or baffle, placed in front of a loudspeaker diaphragm to diffuse the sound waves.扬声器纸盒：一种装置，例如锥形体或反射板，放在扬声器膜前面，用来散射声波 |
