The discussion centers on the concept of transmitting carrier wave signals vocally. Participants explore the idea that vocal cords could be used for rudimentary modulation, such as amplitude or frequency modulation, to convey information, albeit at a low data rate compared to traditional communication methods. The conversation highlights that simple forms of data transmission, like Morse Code, can be achieved vocally. Additionally, references are made to monks chanting as an example of vocal modulation that aligns with the concept of transmitting emotive or thought-like data. The mention of the show "Dark Angel" introduces the idea of using sonic waves for communication, suggesting a connection to the original inquiry about vocal carrier waves.
