telephony
n 1: transmitting speech at a distance [synonym: {telephone},
{telephony}]

Telephony \Te*leph"o*ny\, n.
The art or process of reproducing sounds at a distance, as
with the telephone.
[1913 Webster]

Communication, often two-way, of spoken
information, by means of electrical signals carried by wires
or radio waves. The term was used to indicate transmission of
the voice, as opposed to {telegraphy} (done in {Morse code}
and usually called "{continuous wave}" or CW transmission),
radio teletypewriter (RTTY) transmission (also called FSK for
"{Frequency Shift Keying}", the modulation scheme used by such
machines), and later, facimile.
