这里用载波电路的术语来讨论语音合成。演讲者被描绘成一种无线电广播发射机，发出的信息起源于演讲者大脑的工作室，并在声道中的肌肉波动中表现出来。虽然这些动作包含了信息，但它们是听不见的，因为它们是以音节速率发生的。需要一种听得见的声音将信息传递到听者的耳朵里。这是由载体提供的，载体是一组在声带或声道中其他地方的振荡作用所建立的可听范围内的高频波。这些载波在其产生或其传输中被消息波调制以形成语音波。由于语音波包含可听载体上的消息信息，因此它们适于由收听者耳朵形式的接收机广播接收。然后，信息被听众的头脑恢复。
Speech synthesizing is here discussed in the terminology of carrier circuits. The speaker is pictured as a sort of radio broadcast transmitter with the message to be sent out originating in the studio of the talker's brain and manifesting itself in muscular wave motions in the vocal tract. Although these motions contain the message, they are inaudible because they occur at syllabic rates. An audible sound is needed to pass the message into the listener's ear. This is provided by the carrier in the form of a group of higher frequency waves in the audible range set up by oscillatory action at the vocal cords or elsewhere in the vocal tract. These carrier waves either in their generation or their transmission are modulated by the message waves to form the speech waves. As the speech waves contain the message information on an audible carrier they are adapted to broadcast reception by receiving sets in the form of listeners' ears. The message is then recovered by the listeners' minds.
