He attached a telephone diaphragm to the needle in the telegraph repeater; in this way, he was able to reproduce a recording that could be played back. After he made some improvements to the machine, he tested it. He recited “Mary Had a Little Lamb” into the machine and played his voice back to a very surprised audience.
