<P> Thomas Edison tested the Reis equipment and found that "single words, uttered as in reading, speaking and the like, were perceptible indistinctly, notwithstanding here also the inflections of the voice, the modulations of interrogation, wonder, command, etc., attained distinct expression ." </P> <P> In 1947, the Reis device was tested by the British company Standard Telephones and Cables (STC). The results also confirmed it could transmit and receive speech with good quality (fidelity), but relatively low intensity . At the time STC was bidding for a contract with Alexander Graham Bell's American Telephone and Telegraph Company, and the results were covered up by STC's chairman Sir Frank Gill to maintain Bell's reputation . </P> <P> An early voice communicating device was invented around 1854 by Antonio Meucci, who called it a telettrofono . In 1871 Meucci filed a caveat at the US Patent Office . His caveat describes his invention, but does not mention a diaphragm, electromagnet, conversion of sound into electrical waves, conversion of electrical waves into sound, or other essential features of an electromagnetic telephone . </P> <P> The first American demonstration of Meucci's invention took place in Staten Island, New York in 1854 . In 1860, a description of it was reportedly published in an Italian - language New York newspaper, although no known copy of that newspaper issue or article has survived to the present day . Meucci claimed to have invented a paired electromagnetic transmitter and receiver, where the motion of a diaphragm modulated a signal in a coil by moving an electromagnet, although this was not mentioned in his 1871 U.S. patent caveat . A further discrepancy observed was that the device described in the 1871 caveat employed only a single conduction wire, with the telephone's transmitter - receivers being insulated from a' ground return' path . </P>
